We have a satellite office connected via a VPN (setup on a Juniper firewall). While most users have no trouble, some users will randomly loose the ability to access shares at the primary location.
Other VPN resources (including access to the Exchange server that is on the same physical machine as some of the shares) remain intact. Rebooting always fixes the problem. I've tried mapping the shares via IP address rather than server name and this seems to work better, but is still not reliable for all users.
The clients experiencing the issue are XP the server with the shares is Winodws 2003. Any ideas?
