Windows Workgroup question

Hello,

I’ve got two server2003 machines networked together. Server A is a member of workgroup “One” Server B is a member of workgroup “Two”

On both servers when I am logged in as Administrator, when I browse the Windows network I see BOTH workgroups and am able to access resouces on the other server. I thought that you could only see other computers in you own workgroup. Is this a special feature on Server 2003 that isn’t on XP?

Any info is appreciated!
