Recently, i had to re-do my entire domain when a migration between a windows 2000 server and windows 2008 R2 failed.
What i basically did was to remove the old domain controller and the old domain, and recreated another domain controller and domain. The thing i did was to have the new and old domain have the same name.
For the first few days, everything was fine, users could access shared folders, printers, etc with no issue at all. DNS was fine etc.. ( i am guessing this started when the PCs were renewing DNS entries from the new DC and hence a conflict)
That was the case until yesterday, when things started to act up, a few accounts and computers started having difficulties logging in with the error "login failure, the target account is incorrect. " . I tried removing the affected PCs and PC accounts from the domain and re joined them again but still no joy.
When i tried to rejoin them (the PCs) i too got the exact same error " login failure, the target account is incorrect"
I have verified that the network settings were correct.
I have tried to flushdns to clear dns cache but still no joy.
Trawling through the internet, i seen people resolving this with a simple re join to the domain, but however i am not even able to that as of now.
I think its only a matter of time before all PCs in my domain get affected.
What else can i do to resolve this? I am guessing is the new DNS server of the DC that is probably causing a confusion between the old and new domain.
I ran the command "Nbtstat" and found no conflicts in domain controller or computer name. So i am at a loss here.
Can someone please advise?
