PC works for a local user only -- why????

[bloomlight]

I have a PC in the office with weired situation. It only works with a local user log in.

Here is the situation:

* If I login as the local user, it is OK to connect to Internet and domain server. But it won’t allow to install any program because she does not have local admin permission.

* If I login as local admin, everything stopped. I cannot get on to Internet and the domain server.

* If I login as domain admin, I can ONLY access to domain server, but not the internet access.

Every time I try something. The computer stopped working. Then I have to restore it back to what was before. I never have this situation before. It is really weird.

I have tried several times to change that user to local admin right. But failed.

How to fix this? Any ideas?

Have you ran any hardware tests? Would recommend Ultimate Boot CD to test the HDD and RAM.

is the PC known to the DC?

Even if the trust relationship was hosed with the DC, the local admin account shouldn't be having issues. Sounds to be like a failing hard drive or infection. I'd start by testing the memory and HDD as DrBob suggests.

I'm with BadBigBen. Maybe remove workstation from domain, clean registry with CCleaner, scan for hardware problems and viruses and then rejoin domain.
