What firewall is it?

 

[karan_gr81]

Its Normal windows firewall on PC1 and 2...
PC1 have Norton antivirus installed as well but PC2 doesnt
I was able to connect earlier without problem.

I don't think that the Windows firewall would block a connection being made.

Yes, me too, so any solution??

Solution? I don't even understand the cause yet.

For the configuration that does not work please show for both PCs ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
