I have set up a site to site IPSec VPN and that is further locked down to allow TCP and UDP 139 and TCP 3389. yesterday it was working fine but now we are having "No network provider accepted the given network" error message but we can still telnet to the ports without any problem.
Any suggestion would be helpful.

Try running "sfc /scannow" from the cmd prompt. This sometimes fixes this problem.

it is asking for the windows CD and saying the file version is incorrect. it was working fine before ( on Friday) but it stopped from Saturday.

Possibly an automatic update has corrupted a system file - sfc is the system file checker;
try rolling back any updates after Friday to see if this solves the problem.
(sfc will want the OS disk to verify files)

there is no windows update was installed after we implemented the changes. it was working before and suddenly stopped working 3 hours after I applied the firewall restrictions.

What did you restrict on the firewall?
It seems that the changes you have made are preventing connection; this would suggest that once you had changed whatever, it replicated through NTFRS and then your connection stopped working, so look at the settings you changed to check that everything is correctly applied.

I allowed TCP 139 and UDP 139 that is file sharing port. after this everything was working fine. we are using IP address to access the remote server.

Thanks I will test this and will come back to you. since this is a prod firewall we are only allowed to touch it after office hours.
