Weird! "2 Posts" but only one appears to exist (the one above).
I don't get it.
Scroll down to Post #7 and click on the ScreenShot Picture/Thumbnail.
That's what an F8 Screen should look like.
So you're saying in Safe Mode a user-id of "other user" (literally?) is coming up? You're saying that "If I put my info in it", how can you do that? There should (normally) still be a Welcome Screen to select for "Safe Mode" so WHAT "info" are you entering.
You also finally state "the specified domain either does not exist or could not be contacted" which means that this Computer has to be a member of a Domain in order to logon (the logon credentials are located on the Domain, not the Local Computer). Normally, this would only be done on a Business Vista (Vista Business, Enterprise, and Ultimate).
Who set this computer up, i.e. where did it come from? This sounds really odd to me.
Please provide more specific information.
