Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve network problems, click Diagnose.

Hide Details Diagnose Cancel

Error code 0x800704b3
The network path was either typed incorrectly, does not exist, or the network provider is not currently available. Please try retyping the path or contact your network administrator."

And when I click "Diagnose" I get the following message

Can some one pleas help me

PPS. Can't access My c: drive now, not even when I boot from XP
XP is on d: og Win7 is on C:

It sounds like it is trying to look for a network drive of some sort for your system - try running a Startup Repair from the DVD

This is what MS has to say about your error:
You may experience various problems after you install the Microsoft Security Bulletin MS05-051 for COM+ and MS DTC

You may also need ro re-activate your product key

no security updates were installed. and, even if i wanted to follow the steps in the advisory, i cant, since i cant access %windir% to check the security settings of CLB files. i get access denied when trying to access anything outside C:\Users\<currentuser>

EDiT: after hours of reading forums, advisories, IRC channels and skype-conferencing with IT guys, i resorted to the ugly solution: fresh install.

without a solution, or any idea what might have caused this issue, i just hope it will not happen again.
