Connecting across Subnets - Vista vs XP/2003

My WAN group recently made a change to our pivate WAN which removed the PIX
firewalls between sites. All traffic is now routed over layer three switches.

Since this change happened I can no longer connect to a SQL 2000 server
located in a remote office, BUT only from XP and Server 2003 clients.

I can still connect to the SQL 2000 instance from my Vista workstation.

Traffic is not being filtered and there is no SQL packet inspection going on.

Has anyone else run into a similar problem or can you give me any clues as
to why Vista continues to work but I can not establish connections via XP or
2003.

Thanks,
Jared
