I've got an issue where 1 of 5 clients at a location turn on their PC and it takes about 1 hour for her network drives to allow her access. All other accounts are working, though this did happen one day to another user. When they try to connect to the server share, it says the servername.domain cannot be found. But I can ping servername.domain.
If I //ipaddress I get a login prompt but when entering credentials, I get account unknown or login unknown.
After about an hour, everything works as expected.
My suspicion is it has some unhealthy AD issues and I need to fix all of them, but want to double check we all agree and this isn't something I can fix in the mean time. Their PDC was a 2003 box but we migrated to server 2012 about 4 months ago. I had no issues on the transfer and powered up the old unit just to make sure it wasn't looking back for something and that did not solve the issue.
Any tips are welcome. We are currently leaving the PC on overnight and everything remains ok. But if a restart happens... gotta wait about an hour.
Workstations are Win7 Pro.
