One of the graduate students relocated his computer from one lab to another over this weekend and came across a new (new to me at least.. ) connectivity problem. The connection is enabled, but can't receive any packets. [As seen in the connectivity statistics]. More interestingly, the W2k Command line has gone nuts.. won't recognize commands like ping, ipconfig, traceroute.. not even 'help'. It just gives 'ping is not recognized as an internal or external command.. etc'..

Tried Disabling and enabling TCP/IP.. didn't work. I don't wanna ask him backup his data, and reformat unless thats absolutely necessary.

Any help in this regard would be really appreciated.
Thanks,
