A really strange error with Active Directory Domain.
My customer has a small business with 2 x HP Proliant ML110 G6 servers installed ith VMware ESX 4.1.
He has 7 Windows 7 64-bit workstations in a domain. He has a Windows 2003, 32-bit Domain Controller and 5 of the machines are in the domain. The other two are in a Workgroup and have DNS and DHCP on Windows 2003 Servers also 32-bit. All of these run as VMware Virtual Servers on the Proliants.
The workstations in the Domain are all Windows 7 Ultimate 64-bit. Everything has been working well for almost 3 years. A few weeks ago, they setup an extra server but decided that the VMware Server that the DC was on, was running low on memory, so they Cloned the Windows 2003 DC to the other VMware server. They say that everything was fine until they discovered that the shared printers no longer worked and various other problems.
That was when I got involved. When I checked Control Panel --> System --> Advanced System Settings --> Computer Name, it shows the Full Computer name (plus domain), the Domain BUT...
The Network ID is greyed out but the Change Button is OK. If I click the Change Button, Member of Domain shows the domain name, but it's greyed out.
I shut down the cloned Domain Controller and started up the original one, but this didn't make any difference.
I tried taking one of the workstations out of the domain, but when I tried to put it back, the Domain stayed greyed out, so no way to put it back in. Netdom is also missing from all the workstations.
They had a backup of this workstation, so I restored the backup and Voila! the computer was back in the Domain.
Unfortunately all the backups of the other win7 Workstations are WAY out of date.
Does anyone have any idea as to how to fix this problem?
