Inheriting a domain controller from another company

Backstory. Our company acquired another company and when we took over their servers another tech P2V their entire setup from citrix Xen to VMWare. After they were powered on to my knowledge nothing has changed on them for a couple of years. I have somewhat limited knowledge since I didn't build these systems or p2v. Last Friday symantec endpoint was removed off of all the servers because it was outdated. Now the terminal servers can't communicate with their primary controller by \\server\share without it asking for logon credentials. If I try to browse to shares \\server\listofshares by server name or by IP address it locks up.

I have looked at windows firewall and F & P sharing is enabled, route print looks fine as well no static routes or irregular network routes. I can access the terminal servers C$ share if I browse to it from the domain controller, but not the other way around.

All of these are Windows 2003 SBS SP2

Check that the time isn't too far out of sync between the terminal server and domain controller - this could potentially prevent logins

Your last statement is a bit confusing "All of these are Windows 2003 SBS SP2"
There can be only ONE SBS server in a domain.    I should also point out that SBS 2003 was end of life a couple of months ago.

have you run DCDIAG on what you consider to be the domain controller?

Sorry the DC is sbs, the rest is 03 standard.

I went to open active directory and it gave me an error "naming information cannot be found."

This registry fixed allowed me to open AD http://support.microsoft.com/kb/947022/en-us so when I run dcdiag now I see more errors than before.. FSMOCheck, unable to connect to netlogon share, sysvol replication, systemlog, all of these failed

When did the issue start? over the weekend?  Do you have Friday backups

stlhostAuthor Commented:
Yesterday after I removed symantec endpoint protection. They are on backups yes but trying to avoid it. Was able to repair all of those errors using https://support.microsoft.com/en-us/kb/315457 but still unable to access the shares so I dont know if it just needs time to rebuild or what.

I would restore to get everyone working again and verify the DC is in good shape as is FSMO.  Make sure you are not in journal wrap and start the migration.  SBS 2003 is dead and was also never supported in a Virtual environment.
