Win Server>>WinXP

Hi there, in my work place we have a small LAN, some PCs on the LAN are installed with Win2000 srever, and others with WinXP, the question is: why i cannot ping PCs with WinXP from PCs with Win2000 server, but i can ping from WinXP the PCs with Win2000 server...?

It's probably due to the firewall built into Windows SP SP2.

also i want to add, i can see shared files on Win server PC from WinXP PC.... may the reason is not the difference in OS for PC s, i tihnk may be there is some think else or firewall as you said...

Turn off the firewall on one of your XP PCs as a test. That will soon prove the point one way or another
