Domain Login Issues
Posted on 2011-04-27
I do IT support at a private school where we have a network of 25+ computers with the server running Windows Server Standard. We utilize a domain scenario whereby each computer uses a specific DNS server to point them to the domain. In my lab of 17 computers I had a computer that needed a new power supply the other day and I changed it out. Not sure if having the case open, etc contributed to the problem or not, but I realize it becomes part of the troubleshooting issue, so I mention it.
I run DeepFreeze on these computers, which is a program that reverts the HD back to it's original state each time it is rebooted. Because of this, it only keeps the generic domain user and mine in the user information. All others utilize the Default username to set up their desktop etc. Their username is stored on the computer until it is rebooted. All computers in the lab are Dell Vostro 200 running Windows Vista Business.
This computer that I'm having an issue with, will allow the generic and my login whereby these can access all the network resources, but if a "new" user attempts to log in, it gives the "username or password not recognized" error.
Other pertinent info:
When I look at the users in the computer/properties/adv sys settings, I see several "Unknown Accounts".
It's definitely not a user issue (i.e password, expired/locked account, etc).
It's definitely related to this system specifically (as opposed to its location)
DNS server is set correctly.
Help anyone? Thanks!
