So far, there are no published reports for MS05-051 which some security firms feel has the potential to be crafted into a possible Internet worm, that could especially impact Windows 2000 based PCs and Servers.  At least 3 proof-of-concept exploits were developed within a couple of days of the October 11th updates, so companies should carefully test their applications and patch expediently.  All users should stay as up-to-date as possible on any security patches that are released.
