I have noticed issues with the past several versions of Microsoft Windows servers with reconnecting a computer with the same name on to the domain.
We are currently running SBS 2011. This has happened twice this year. The first time a computer crashed and I had to rebuild it. I used the same computer name as before and it would connect to the domain but would not have a good consistent connection to the server. To resolve it I renamed the computer and connected it to the domain. The second time, the computer is a MacBook Pro running Lion with Parallel's version 9. When I first installed and setup windows7 through Parallels it worked great. We had hardware issues and in troubleshooting we uninstalled Parallels. When we re-installed Parallels the Windows 7 profile was still there but it removed it from the domain. When I reconnected to the domain it had the usual connection issue. As last time, I renamed the computer in Windows and reconnected it to the domain. This time it did not fix the problem.
Any ideas for suggestions?
