Strange Internet Connection ISsue

My setup is as follows:
2 pcs running XP Pro SP 2 connected to wireless router.

Before the weekend both PCs where running on the internet without hassles.  Yesterday I re-installed XP Pro and SP 2 on the one PC (PC A).  PC B is still running fine connecting to the internet without hassles.

PC A experiences the following.  If I reboot it and stop at the login screen I can ping PC "A" from PC "B".  As soon as I log in on "A" I can not ping "A" from "B" any more.  I also can't ping the router from "A" (let alone PC "B").

The network connection status on "A" says everything is fine and connected to the network at almost full signal strength.

Both PCs sits on the same workgroup, and subnet and both have static IPs:

I've noticed at one stage there are 3 network connections in the connections list:
1.  The ethernet connection (which I have disabled and re-enabled as various options of testing)
2.  The wireless connection (which it says is connected).
3.  An "Internet Connection" which says it is connected through the internet gateway (?)..  I've tried to disable this but it says it can't disconnecte because it is in the process of connecting or disconnecting and I can't change this.  I've made sure on all the connections Internet connection sharing is disabled, and then I also Un-Installed the ICS option via the control panel's Add/Remove Components dialog.  

Since uninstalling the ICS option the last connection item is not shown any more, but I still can not connect to the router.

Any ideas or suggestions ???

disable the windows firewall, then try again

Sorry - forgot to mention that:

on PC "A" where the problem is there is no firewall or antivirus running.

I have zonealarm running on PC "B".

Are you sure that Windows Firewall is not running on computer A, it is enabled by default when you install XP SP2.

Check the config of zonealarm on B and make sure it is not blocking A
ebenvAuthor Commented:
Firewall on A is disabled and even after disabeling ZoneAlarm on B it still does not work.
