Workstations cannot see workgroup afetr installing Windows Server 2003 R2

We just installed a new server at a site and set up an active directory
domain for the users. They can log on to the domain fine, but they
cannot browse their previous workgroup. The only thing that shows up in
"entire network" is the new domain. I am thinking this is due to some
new security policy in R2, but I can't seem to find it. Any help would
be GREATLY appreciated!
