Compromised Windows Server Jun 05 2006 07:27PM

Came in this morning to find a windows 2003 server I manage scanning the
Internet for machines listening on tcp 139 and 445. While looking at the
machine I noticed the following processes running.

Mwvsta.exe found in c:\windows\system32

rundll16.exe c:\windows\system23

Ponoas.exe c:\windows\system32

I believe that the ponoas.exe is some sort of rootkit although searching on
google for this file name returns nothing. Also searching
mwvsta.exereturns nothing. At this point I have removed these files
from the system
and registry but am weary that the server will get hit again. Has anyone
had an experience with the following file or have any idea what rookkit of
virus they are associated with?
