I am running XP pro on a desktop connected to a wireless router via
ethernet cable, my laptop is connected to the same router wirelessly.
Both computers are set to MSHOME and I have disconnected all firewalls
except for microsoft windows firewall. I can see and access all shared
documents from the desktop but the laptop can not see any of the
shared documents on the desktop.

Here is a network troubleshooter by MVP Hans-Georg Michna. If you are
still having problems after you try the above suggestions, take the
time to go through Mr. Michna's troubleshooter. It normally pinpoints
the problem area(s).
