Hello r/MDT,

i'm currently planning an SSD upgrade and OS upgrade from 7 to 10. My first idea was to add a suspend step after the user state scan allowing for the PC to be powered down and disk to be swapped. Unfortunately i can't seem to find a way to make that work in a PXE. My next thought was to run scanstate via PDQ and automate the loadstate path but i can't seem to get loadstate to run if scanstate is not run. at this point it's looking like i might need to just run a powershell script after the install to run the loadstate automatically but i was thinking one of you geniuses may have another idea or solution to my first two thoughts.

Depending on the amount of user data, your network, and available storage space, the MDT replace task sequence would help automate the process.

https://docs.microsoft.com/en-us/windows/deployment/deploy-windows-mdt/replace-a-windows-7-computer-with-a-windows-10-computer

Setup the shares, MDT rules and replace task sequence. Run the capture/USMT on the workstation, swap the drives, then the deploy/restore.

sorry if i'm just not seeing it but how does the example in that link specify where the MIG file is located? is it assumed you are manually entering the path during the deployment? i already have the files saved in \\server\share\%serialnumber% so i'm trying to automate the restore from that path so my guys don't have to type it out on each machine.

I've recently setup a new printer VLAN at each of our sites and was able to migrate the wireless printers over fairly easily with a bit of cheap labor to connect to the new SSID. I'm now looking at tackling our existing wired printers and i'm wondering what would be the most efficient method of doing so? My current idea is to get a list of MAC addresses and find the ports via ARP. While this is still a fairly big task i can't think of any other way to go about it.

Also on a related note, do any of you groups physical VLAN interfaces together or is it just as effective to configure the VLAN on whatever port the device happens to be plugged into?

802.1x and DHCP is the correct answer here.

Original Poster1 point · 4 months ago

DHCP is definitely going to be utilized. I'm just not quite sure how to leverage 802.1X to assign VLANS.

802.1x is a method of authenticating a device before giving it access to the network. Part of this authentication can be an authorization. As such, your policy server can instruct the switch as to which VLAN the device is authorized to connect to.

Basically, the switch says "hey this guy wants to connect to the network" and your policy server responds by saying "yep, allowed, put him on VLAN X".

For printers, you can use MAC-address-Bypass to classify based on the MAC address. Then you just need a list of MAC addresses on your policy server. Or you could use EAP-TLS.

Packetfence is a popular free policy server.

After a bit of research I think I got the gist of it. I already stood up a Windows NPS for the Wireless RADIUS authentication. I'm going to try and setup EAP-TLS and authenticate with a generic service account since all of our printers are 802.1X capable. I've already configured the policy just need to configure a switch port and test.

Thanks for the info!

Ahhh figured it out. I had to enable "DHCP Profiling" and "DHCP Addr. Assignment" in my WLAN to get the hostnames to show up. Not sure about the usernames, but this will do for now. Thanks for the help

Where did you find this information? I'm trying to view client hostnames as well but only getting a username column. I've already enabled both of those settings on the WLAN.

Original Poster2 points · 4 months ago

Display the clients in the "clients" section of the Network Summary tab. From there click on the arrow next to Name and select columns. you will be able to add in HostName from there.

Hello r/plumbing! I was hoping someone more knowledgeable than myself could provide me with some advice. Today I've noticed that next to the main drain access in the back yard of the house I am renting there is a fairly deep hole that is apparently filled with water. Originally I thought "crap, there's a sink hole in the yard". Upon further inspection I believe it is the septic tank as it has a pretty nasty smell coming from it and I can hear water draining to it whenever the water is on in the house.

Currently the hole opening is about a foot and a half or so under the surrounding dirt. Originally I thought I had a gopher that really liked to dig there and would just fill it in every now and then. I'm assuming the recent rain we had washed that dirt into the tank and now there is an open cavity. I'm assuming there should be a lid covering the opening right? The hole is definitely big enough for my cat to fall in and I haven't verified the actual diameter of the opening so it could even possibly be a hazard for my dogs as well if they decided to dig there. Not to mention any small family I have over.

Obviously I'll be calling my landlord about the issue and he is going to give me grief because he's had a few plumbing related issues the year that I have been here. I guess I'm just wondering what I should be expecting. Does the dirt just need to be dug up and the lid replaced? Or am I completely off the mark?

Tldr: got a deep hole in the back yard with water in it. Thinking it's the septic tank with a missing or broken lid. Looking for input.

If your lid is gone, your tank is so much more fucked, it's only funny because it's not mine.
If you have a water softener and it discharges into tank, the brine will destroy concrete. If it's a steel tank, it's the same thing.

Would you mind elaborating on this? I'm assuming it's a steel tank since a quick look with a flashlight revealed a metal container.

Steel and moisture don't last.
Have you ever had your "septic" tank pumped before

Our district is finally pulling the trigger on replacing our old SB600s. After having a bid war between Viewsonic and Smart we have decided to go with Smart as they only came in a few hundred dollars higher and out teachers have so much time invested into the notebook software. My boss came to me asking what my thoughts were on how to drive the device.

The board we have been demoing currently has a HP Prodesk mini sitting behind it that has fared pretty well, however it is not the most elegant of solutions plus we'd have to tag on the price of a mini PC for every install. All of our teachers are currently running Thinkpad E5X0s so the cheaper option would be to just run an HDMI from those. Then there is the less friendly option of just running the native smart apps on the board with no PC connection. I'm not sure how fully featured the Notebook software on the 7000 is and out teachers still have tons of PDF/JPEG files they use in their lessons. Although i suppose those can be easily converted to notebook files.

So basically i was just wondering what the rest of you folks use for your interactive displays and how you are liking the solution thus far?

Are you factoring in the price of the Smart Notebook subscriptions as well?

Original Poster1 point · 7 months ago

The consensus was that we would continue to pay for the smart notebook subscription no matter what platform we went with. Apparently the price of the subscription increases substantially if not used with a smart device so it was actually a cost savings in a sense.

Honestly that looks like a calyx that has been fertilized by pollen in my opinion. That back cross section appears to even have a little seed shell

Yesterday I purchased my first big boy light. It was a Hydroplanet 1000w de setup, supposedly brand new, still in the box. I brought it home, hooked it up and it worked fine. Later that night I got my grow area all setup, light mounted and timer set up.

This morning when I woke up the light was off but the timer was on. I realized the ballast wasn't working, no fan or anything. After a bit of troubleshooting (cables, outlets) I decided to pop in the spare fuse. I'm pretty sure the fuse popped as soon as I plugged it in. It was a small popping noise almost like the sound of arcing. I haven't been able to test the fuses yet.

What do you guys think is the issue? Bad ballast? Bad power? I popped the top off the ballast and nothing is noticably wrong. In the mean time I've ordered some fuses from Amazon and contacted Hydroplanet customer support via email. The light is supposedly only 6 months old but idk if they will honor the warranty without a receipt or order #. Sigh... I was so excited to grow with a big boy light.

I've had this happen but only when not plugging the ballast and timer directly into an outlet of their own, anytime I try doing timer/ballast + surge protector/extensions, etc, the timer fails to ever ignite the ballast.

The fact it's running fine minus the timer makes me think it's the timer/placement of it

see more
Original Poster1 point · 7 months ago

I probably could have worded it a bit better. Initially it worked for about 20 minutes while plugged into the timer before shutting off. After swapping fuses I plugged it directly into the wall bypassing the timer. That's when it immediately blew. At that time I did not have the bulb plugged into the ballast. Could that have caused it to blow? I didn't think the bulb needed to be plugged in to fire up the ballast.

1 point · 7 months ago · edited 7 months ago

I believe so unfortunately, every digital HID ballast I've owned had warnings on not to attempt powering it on without a reflector/bulb.

Looking through a few DE ballast manuals, they say to power off between relamping or when doing any maintenance/adjustments :\

Hopefully you don't have any issues getting it replaced dude

Original Poster1 point · 7 months ago

Hmm that could be good or bad. Maybe I just blew the spare fuse due to not having the lamp plugged in and the first was a fluke. Guess I'll have to wait until the fuses get in to find out.

So this has been an issue with our environment since i started working here. Originally folder redirection was only enabled for District office staff (15 or so people) so i just disabled it on my PC and left it be. It has come to a point where we want to start pushing folder redirection for all staff so i need to figure this out. Basically, instead of just syncing the users directory it attempts to sync from the root of the share. for example the users share is \server\teachers\user. Offline files attempts to sync \server\teachers. I thought maybe it was any issue with the original configuration in group policy but i have started from scratch and still getting the same issues. Any input is appreciated.

This is more of a Thickheaded Thursday post but i'm a bit late to that party... Anyway I'm attempting to setup Folder Redirection in our environment and was going to start with a couple of newer users that are getting new PCs here in the next few weeks. I got the policy setup and originally planned to ad the users to a security group and add that group to the GPO security filtering. When i do that the GPO does not apply. I tried setting the filter to the specific users and still no dice. however when i change it back to authenticated users it applies. I have no clue what the heck is going on here.

FIXED Should have tried google first. Apparently a patch came out a while back that changed the way security filtering for users and groups works. In order to filter by users or groups you need to give authenticated users read rights in the delegation tab.

I remember when those patches hit, what a PITA. Microsoft says it's to help prevent man in the middle attacks. Here's a link about it: https://blogs.technet.microsoft.com/askpfeplat/2016/07/05/who-broke-my-user-gpos/

If possible, I'd recommend using auth users in the security filter as normal, and use item level targeting to get granular with the deployment. If you're not using ILT already, it's very easy and powerful.

I do use ILT for most deployments but was under the impression it only applies to GPP. Is that not true?

FWIW, as a band aid, with our ruckus gear we were able to create another open SSID and limit the OS/Type to chromebooks only. This should allow google to fix the policies and the Chromebooks should reconnect to your preferred SSIDs if needed.

We just stopped all of our chromebooks from updated pinned them at the version they are at, going to see if this bandaids the problem.

We are using Aruba AP so it’s not just restricted to A single AP at this point based on the comments.

it's unlikely as mine have been pinned at 59 for a while now.

I have been attempting to tack this issue for a while now with no luck. Every so often we get a ticket about a user having network related issues. Get to the users PC and notice there is an APIPA address assigned. 9 times out of 10 a quick ipconfig /renew fixes the issue immediately. I have no clue why they are not picking up an IP in the first place. We don't seem to be having this issue with any Chromebooks or non-windows devices so I'm tempted to assume it's a software issue on the OS end. Driver/bios updates don't seem to have any effect either.

FWIW we're running a Cisco 5508 as the WLC and all traffic is on the default vlan. 5508 is set to DHCP proxy mode. DHCP server is on the local subnet as well.

I had this issue on dell laptops it ended up being a setting on the NIC. Every time the device went to sleep the NIC for some reason grabbed an APIPA on wake. I believe it was a power management setting.

Maybe set the NIC to never sleep? I've had this happen in dells as well as thinkpads.

why they are not picking up an IP in the first place

Troubleshoot your DHCP:

  • Broadcast not reaching DHCP server

  • DHCP server too slow to respond

  • Use Wireshark

Hint - are those 'randoms' clustered by time, or location?

Original Poster1 point · 8 months ago

The instances are few and far between. I'd have to have Wireshark up and running for days in hopes of catching it.

Can't seem to find any pattern at all. 3 different sites all experience the same issue. I want to say their all windows 10 machines but I can't say for sure.

Has anybody had any luck with this? i used the guide here and it does say that the system is applying updates for a split second before rebooting. When i check the BIOS it still reports the old FW version.

I need to update the firmware before it will allow me to PXE boot using the newer M$ USB to Ethernet adapters.

Did you push the network via GPO? Once I did this any domain device logged in as a domain user was automatically signed in with their credentials.

I had the same issue after initially rolling out windows 10. Ended up just pushing out the latest cumulative update to clients via PDQ and that seemed to fix the issue.

I recently stood up our first ever NPS server to test and eventually deploy radius authentication on our internal WLAN. Everything seems to work fine for the most part but something i've noticed is that, although i have Computer & User authentication enabled, the local admin account does not connect to the WLAN. Prior to logging in the computer account is granted access to the network but as soon as i log in as local admin it disconnected and prompts for credentials when attempting to reconnect. I'm aware i shouldn't really be using the local admin account anyway and will be working on moving away from it going forward. I'm really just curious on why this is happening. Does RADIUS prefer user over computer authentication?

Machine based auth is the way to go here. Typically with windows if you're setting wi-fi to auth before the user sign in it will use the user credentials provided in the login prompt to auth against the wireless. If you use the local admin account that doesn't have an AD account connected to it which means it can't auth against AD which means no wi-fi.

That being said, machine based auth is a whole other kettle of fish. I don't know of a situation where you'd use both at the same time but I'm also PFY as fuck.

I have it set to compute and user auth. The computer account is not having any issues authenticating. I can see in the logs as well as the sign in screen that it is connecting with the computer account credentials. The issue does not occur until after logging into the local admin account. I was hoping if the user credentials failed it would fall over to computer credentials.

So about a month ago I decided to start getting serious about learning Powershell. I had stumbled upon Jon Walz Powershell podcast and managed to find a webpage that listed all the podcasts from episode zero onward. The sweet thing about it was the podcasts would play through, episode by episode, automatically. The player even have a 15 second rewind button in case I missed what was being said. I cannot seem to find that page for the life of me. I checked through my history, seen the Google searches I did but I can't get back to that page. I'm not sure if they decided to update their website layout the day after I discovered it or if I'm just crazy. I thought maybe one of you guys might know what I'm talking about. It's driving me nuts!

On PCs running windows 7 i generally would set sleep to never and turn of display after 20 minutes to conserve monitor life. This way Monitors would shut off but teachers would not be forced to log in again. Now on windows 10 it seems like the session is locked when the display turns off even if sleep is disabled. Am i missing something or is it no longer possible to accomplish what i was doing before? I'd prefer to set this up via group policy if possible.

Thanks in advance!

Windows Key->Settings->type "lock screen" in search bar, click "Screen saver settings". Uncheck "On resume, display logon screen".

This is how to do it locally. You’ll want to do it in group policy because it may keep over writing your changes if there is already a policy

Found this on google already unfortunately it doesn't seem to work. i have that box unchecked but i still get the lockscreen after the display turns off.

I use RSAT tools on my laptop in two different domains. You just have to make sure you run the tools with admin rights for the respective domain and select the correct remote server.

I haven't been able to find much on this subject besides this post here: https://productforums.google.com/forum/#!topic/chrome-admins/v1MzYsEB2sU

We recently had two of these installed in our district and they are showing up on every chrome device and browser. apparently kids haven't noticed yet but when they do i can only imagine the outcome. Anybody dealt with this and know how i can disable this printer side? I don't want to have to disable printing in chromebooks and roll out GPOs for this if i can avoid it.

Edit: it was Bonjour. For this specific printer it's under network settings>TCP/IP. I was looking in protocols hence why I didn't find anything.

Just bought a cheap Chinese bike and it has a few issues that I'm working through. I'm very new to bikes in general so please bear with me.

The front left fork seems to be leaking. I'm going to try and clean it out before taking it in to have the seals replaced as dirt in the seal seems to be a common cause for this. However, the wiper seal on that same side does not stay in place at all. One pump on the forks and it comes right out. I can also pull it out with just my fingernails. I'm thinking it's just an old seal that has shrunk slightly due to drying out. Is there anything I can use to try and plump it back up or should I just bite the bullet and get all the seals replaced?
