On my home wireless network using Linksys WRT54G v5 router I have a desktop and a laptop. The laptop runs Win XP Professional Edition while the desktop runs home edition. Both are SP2. A printer is attached to the desktop.
While I can always connect from the laptop to the desktop, I am unable to do so the other way round. Even while pinging, I see I am able to ping from laptop to desktop but not from desktop to laptop. Interestingly I am unable to also ping from my desktop to itself though I can ping to the Linksys site properly.
Three important points:
1. The laptop is HP Compaq nc4200 with HP Credential Manager for Protect Tools installed that I am forbidden from removing by my company.
2. A few weeks ago based on a tip from the internet I configured the Windows Firewall to open ports through the Exceptions tab and it worked. After that I had a system reinstall on my laptop following which I tried recreating the settings but it did not help. It is no longer working now.
3. Windows Firewall is diabled on both computers.
