Hi Siddharth-
This could indicate quite a range of causes. An unfortunate one is that
this can be caused by a virus inefection. That may not be the case with
yours though.
You can temporarily try re-adding your adminsitrative shares by the command
"net share ipc$" at a prompt.
In the meantime, I would check for virii on that machine with the latest
anti-virus and definition files. Some trojans are not easily detectable
though, so it would be a good idea to scrutinize your running processes in
Task Manager for any suspicious entries. Firedaemon is a commonly used
application on a machine compromised by a virus.
Please repost to let us know what you find.
