I was wondering if anyone can point me in the right direction of where to look for a solution to a problem we are currently having. We are upgrading one of our servers from 2003 to 2008 R2. Previously we were able to dial Windows XP client machines from the 2003 server and ping and SQL Server replicate between the two but with Server 2008 R2, the 2008 R2 server can ping and connect the XP machine, but the XP machine cannot ping or replicate back the other way. We've heard that 2008 R2 have disabled this feature, but I would like a 3rd opinion.
