Hi folks!
I've been quiet for a little while, but I'm coming back at you now with some posts that have been sitting with me for a long time.

Since I spoke with you last, Microsoft released Service Pack 3 for Windows XP.  This service pack contains version 2 of the Peer Name Resolution Protocol (PNRP) which is compatible with Windows Vista and Windows Server 2008.  PNRP v2.0 was available as a separate download for XP SP2, but now it comes directly with the service pack.  You can download XP SP3 from www.microsoft.com/downloads.

Have fun!
