Can't join machine to domain after upgrading to Windows 7

[pingmasta]

Hello, I recently upgraded my machine from windows XP to Windows 7. Ever since I have not been able to logon to the domain. The system always logs me on to a Temporary Profile; thus I'm not able to access domain resources.
I resetted the computer account and rejoined the machine back to the domain..but its still not being successful; the error message tells me another system has the same credentials as mine and thus cannot join the domain.
I also tried renaming the computer and pre-staging the computer account but its still not successful.
How do I go about this?

Talk to the domain administrator. It appears your old XP machines credentials (i assume you named both machines the same) are preventing you

Have you attempted to manually enter the Domain DNS servers in the network connection settings of the problem machine?

Doing that has fixed this same problem a few times in the past.

Sometimes the auto DNS settings don't work properly when connecting to a Domain network for some reason, I believe the Domains router firewall blocks the DNS info from being picked up.

Your best bet is narrow down the reasons for the error. Fire up Event Viewer and it should show you some detailed error messages. Post them here.
