I have 2 XP Home machines, one desktop, one laptop. Neither can see the shared resources of the other. They are connected via a Netgear 4 port/wireless router. Desktop is cabled to router, laptop accesses wirelessly.
Laptop is able to access Internet via the router but cannot access desktop's shares nor a new laser printer that is directly connected/cabled to router. When I set up the laser printer the other day using the printer's install program the laptop was able to locate the printer on the network and install drivers but when I tried to print test page it didn't work. Ran trouble shooter and it was unsuccessful at pinging the printer.

Desktop prints to the networked printer with not issues.
I am running Trend Micro PC-cillin Internet security on both machines and have tried to remedy situation by turning off firewall to no avail.

Have tested each machine's IP stack by successfully pinging the loopback address. Desktop is able to ping the router successfully. Laptop is not able to ping router however it is communicating with it in order to get Internet access. Workgroup name appears to be the same on both machines "Mshome".

Sharing did work at one time between machines. Changes since then that I can recall: I've had to replace the hard drive on the laptop and reinstall windows xp. Uninstalled Norton System works/anti-virus and replaced with aforementioned Trend Micro product.

Simple sharing shouldn't be so difficult. Any ideas?
