Let's hope your IT and network guys understand the links from http://www.google.com/search?q="No+network+provider+accepted+the+given+network+path".
It's a slightly different error message ("accepted" in stead of "can accept"), but that might not be a problem.
I facing an irritating problem for the last few days.... I m using my office network, the printer is installed on a desktop, all my colleagues can acces it, but when I try I can't. I can even ping the computer but can not access the shared resources on it.... a message appears when i try to access the IP " No network provider can accept the given path"
I m unable to access even my own PC and the above mentioned message appears. My firewall is off.
