Installation and Upgrades / [Solved] Windows File Sharing over VPN unreliable
« on: November 09, 2012, 01:34:16 am »
I'm servicing a client who has their network arranged across three locations, with a Windows 2008 R2 Enterprise server acting as domain controller and file server at location 1, with client machines in all three locations. The remote locations are connected in to location 1 with Zentyal-to-Zentyal VPN boxes, and everything is working correctly as far as domain communications goes, except for file sharing.
The file sharing itself is working; network drives are being mapped, you can see, access, all the good stuff. But at seemingly random intermittent moments remote locations appear to lose the ability to see the Windows 2008 server, despite pings, etc. all going through correctly at the very same moment. The problem always resolves itself in a few seconds, but one of the remote locations has some network share files constantly open and being worked on, and this network disruption completely knocks them offline and can damage their working files. When this happens, the server usually gets Windows Error ID 2012, but I've exhausted all the options searching for that error gives me. I have narrowed the problem to the VPN link, as the client machines at location 1 have absolutely no problem with extended access to file shares. I'm just not sure where to go from here, as the VPN link seems to remain up when these outages happen.
Any ideas?
