I have tried adding my machine to the domain but keep receiving the following error message
"The join operation was not successful.This could be because an existing computer account was previously created using a different set of credentials. Use a different computer name or contact your administrator to remove any stale conflicting account. The error was: Access is denied."

-After checking the Computers OU in AD I notice my computer account with a red cross through it.

-I have joined XP machines to the domain with no problem.

-I have disabled IPv6

Does anyone have any suggestions to get this working?

thanks
