This module exploits a stack overflow in the NetApi32 NetpIsRemote() function using the NetpwPathCanonicalize RPC call in the Server Service. It is likely that other RPC calls could be used to exploit this service. This exploit will result in a denial of service on on Windows XP SP2 or Windows 2003 SP1. A failed exploit attempt will likely result in a complete reboot on Windows 2000 and the termination of all SMB-related services on Windows XP.

Don't be suprised if someone turns this into a worm. Patch early and often.
