says (On Comp2)
C:\Documents and Settings\Administrator>ping 192.168.100.2 -t

Pinging 192.168.100.2 with 32 bytes of data:

( I have to NIC cards i verified with both unable to ping.)
But i noticed one thing. when i reboot Comp1 and ping is on from Comp2 to Comp1.

It will ping when the Comp1 is just logging. aftetwards it stops ping

Have you disabled any firewalls ?
