Windows 2000 Professional Problems... Help needed.

[Sacred_Devil]

I have encountered quite a number of problems with this Operating System.

Sometime I will get this during the logon screen:

"Logon message
The system cannot log you on due to the following error:
The network request is not supported.
Please try again or consult your systme administrator."

I tried logging in using both the administrator and username account but failed(not due to wrong password).

I don't understand what it is implying. For you info, I have no problem booting in safe mode.

If I logon sucessfully, I will encounter another problems.

I will get this message pop up out of nowhere whenever I use the computer.

Then there's another problem, which is this:

My time setting and region setting is set according to my timezone and it's accurate as it is, but it still give me this error. I followed the instructions but it doesn't help.

How do I solve all of this problems?

Thank You.

You may be beyond patching this. Do you have a legal Windows CD to reinstall if needed?

[Sacred_Devil]

It will take  me a lot of time to post my reply. I don't have the CD. what should I do? Every now and then, there's virus popping. I deleted it, yet it still pop up.

You have to boot to safe mode and delete it. What are you using?

I switched back to windows 98 again. It's running fine now. I guess I am stuck with this for now. Thanks for the help too.
