we are having problem in accessing two server with VPN. we have 5 remote office and 1 main office and they all are connected with VPN. from yesterday i am seeing one problem between two offices. here is the problem:
Server1 from Office1 can see Server2 at Office2. and also Server2 can see Server1 without any problem.
if i do this:  from server1 \\ ip) than i can see all the shares on server2 at office2. but when i try to access any of the share on server2 i can not access it. and same thing happand from server2 to server1. can not access any share.
Error messeges are different all the time...
sometime error is :  "the semaphore timeout period has expired"
sometime error is :  "The Specified network name is no longer available."
sometime error is : " The list of servers for this workgroup is not currently available."
sometime error is : " The specified network name is no longer available."

this both server can ping each other without any problem. both can browse share with out any problem but just can not access anything.
from this two offices other servers (without this two) can access all shares without any problem. just this two can not talk to each other.
even other server from office1 can access everything on server2 at office2 without any problem. same from both side.

If i create any new share on server2 than i can access that from server1 without any problem and same from server1 to server2. but can not access any old shares.
i check the permissions on all shares it is not change from long time. these both servers didnt have any problem before couple of days. they were working fine without any problem.

No permission change, No new nic card installed, no tcp/ip change, no VPN change..nothing change.
but still cant access anything.

i check the event log there is not log for this errors.
they both are windows server 2003. using static IP address.

let me know if you need more information for this problem.

Thank you.

    Did you reboot all servers involved? Usually when something like this happens and there have been no configuration changes, rebooting is a good first step and many times the resolving step.

    I have the same issue.  Did you ever get it fixed.  What kind of VPN appliances do you have?
