We are having trouble with a pair of sites which have two site to site VPN links between them. There are two 3845 routers at each site, A and B; The A router has a vpn link to the other site by the A router at that site, and the same for the Bs. On the LAN side, there are several subnets which use Gateway Load Balancing Protocol (GLBP) to share the load between the routers. On a windows 2003 server on one site if I try to do a remote file share on a server at the other site (\\server-othersite\d$ ) it will timeout after about 10 minutes with an error message "the specified network name is no longer available." If however either of the links is taken down, it works fine. If it was tried and then one link goes down it gets through after about 10 seconds.
My guess is that there is a hash used for the authentication of the remote file share which isn't getting calculated correctly. Anyone know how to get this working?
