User login delayed 1 hour

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.

Open a command prompt and type this command.

set log


This will give you the server your machine is authenticating against (like LOGONSERVER=\\ABC-NYC-DC04).

If this DC across a wan/slow link then some slowness is expected.

I've moved the PC to a workgroup setup and everything is working as expected.

The time to investigate this issue was well outside the time that I was willing to invest, as well as the money that would have been paid by the customer. So I cut my losses and punted. The other suggestions did help me make this decision as they pointed out that this is possibly a known issue and not something I would likely resolve any time soon.
