No registry permission

[Atrye]

I've recently reinstalled Windows XP Professional on a machine at work, and set the machine up with a single administrator user. For some reason, this user doesn't seem to be able to edit the registry, and it's causing problems with some software.

Can anyone tell me what could have gone wrong and how to fix it?

Hmmm WELL let me ask you this, have you changed this PC's name recently? Added to a Domain? Something like that? Can this "Local administrator" do any other admin functions? Like add other users to the local admin group?

I ask because we had a desktop that had a name change, but I don't think was removed from the domain when it did so. Then the local admin was no longer an admin on the box.

I wasn't invovled with it until after whatever it was happened to see that the local admin didn't have rights.

This machine is part of a workgroup on a small LAN but there is no domain in place.

I can't seem to resolve this problem. I've tried renaming the computer, removing from and then replacing it on the network, removing and reapplying each user's admin rights. Nothing seems to fix it.

Does anyone know what I need to do to re-enable registry admin?

What about what I said here? Can the local admin do any other "admin" tasks? How are you trying to edit the registry? Does the Registry editor come up and you make changes but when you close out it's not applying?

Sorry for the super-long delay. Life is hectic.

Except for this problem, the admin seems to function perfectly. I access the registry by Run > regedit and then I manually create a key where it needs to be and enter the data. Everything seems fine and the permissions within the registry seem fine.

However, when I exit regedit and then reopen it, my data is gone.
