2003 Server would not see the rest of the network

I connnected 2 windows 2003 servers to a basic workgroup and both of those servers would not see the rest of the network. I did all the basic tests but nothing worked. Those 2 servers work on another workgroup with no problem. This network has a Birch router (T1 service), 24 port Linksys switch, and a netgear switch.

Any suggestions?

thanks
