WinXP wireless connect to Win2K

I have WinXP Pro & XP Home Ed working with wireless USB Netgear h/w. I want to add 2 laptops (1 has Win2K Pro and 1 has Win2K Server) using same. Base is the WinXP Pro system.

I installed Netgear USB wireless adapter on each laptop and they do show connection to the XP PRO system is strong (11 mbps). However, even though I setup the workgroups to have the same names, laptops do not “see” the XP systems. Laptops are 2nd hand and no Win2k documentation.

WEP is enabled, associated keys are entered. No domain, this is “simple” peer-to-peer network.

I am missing something, but do not know what it is and would appreciate any help. I am self- taught, 3-4 (maybe 5) on scale of 10 (based on what I have read here).

thx!
