Change Computer Name/Domain Changes

[eiger3970]

Hi Windows SevenForums,
does someone NOT from Microsoft (useless, if not negligent support) know how to change the Computer Name?

My PC is connected to my Windows SBS 2008 R2 server with the wrong Computer Name.

1 year ago I tried to setup Windows SBS 2008 R2 server (pathetic lack of instructions make a simple job impossible) and setup my PC with the Computer Name NAME1.

I am now trying to get the Windows SBS 2008 R2 server to work after 1 year of trauma with Microsoft products, so I went to Windows SBS 2008 R2 server, Windows SBS Console, Network, Computers, and see my old connection to my PC named NAME1.

I can't connect my PC NAME1 to Windows SBS 2008 R2.

So...I simply selected from Windows SBS 2008 R2 server, Windows SBS Console, Network, Computers, Connect computers to your network. This wizard connected my PC NAME1, but only when I name my PC NAME1, as NAME2?

When I try to change my PC which is now NAME2 back to the correct and original NAME1 by going to Start, right click My Computer, Properties, Change settings, Change..., type in NAME1, OK, Windows Security asks for the name and password of an account with permission to rename this computer in the domain. I type in superadmin account name and correct password.
Click OK, and error comes up:
Computer Name/Domain Changes
The following error occurred attempting to rename the computer to "NAME1":
The specified computer account could not be found. Contact an administrator to verify the account is in the domain. If the account has been deleted unjoin, reboot, and rejoin the domain.

See attachment for pictures of what Windows 7 is messing up.

Remove the computer from the domain (change to workgroup) first. Then delete any machine accounts that are incorrect from the domain. Rename the machine and rejoin.

This method did put the PC onto domain NAME1, however Windows SBS 2008 R2 still showed Computer NAME1 in Status Offline.

Also, the user's profile settings are all gone.

I then switched the PC on domain NAME1 back to user NAME1 and all the user settings are gone.

I can't find all the user settings on the workgroup or domain, and the Windows SBS 2008 R2 still won't connect?
