I have about 25 workstations - all the same hardware .. all about 3 months old ... all Windows 7 SP1, 64 bit ... all part of a windows domain. Over the last couple of months I've had about 4 of them just simply lose their association with the domain.
Computer starts and the only login option is the local admin account. When I login and look at the users folders, I see two for each user ... where as prior there was one folder for each user. Now there is an additional folder for each user with the domain name tagged on as an extension.
(as a side note, I noticed the newly .domain folder has today's date but a time of 12:27pm (into the future 1/2 day) but the system clock looks right... not sure if this has any meaning)
What I've been doing to this point is logging in as the local admin, removing folder xxx and renaming xxx.domain back to xxx. After rebooting I get option to login as the domain user again and this seems to get almost everything back to normal. Windows and Office need to be reactivated after this.
Anyone have any ideas what could be causing this?
