Windows XP on SBS 2003 domain...pc reverts to "working offline" at random...
Posted on 2009-05-12
This has been an issue for quite some time, but finally i have to resolve it. Working remotely on a customer network, I'm logged in to the server via VPN (PPTP to the server directly). My connection to that server is stable. I use VNC from my PC to the server and user's workstation. Those VNC sessions are stable and do not drop.
The user is a local admin on their machine. the machine is a member of the domain. the user is a domain user. The machine is setup to redirect the users My Documents to a share on the server called "Users" (the UNC is actually \\server1\users). This is significant in that there are at least 15 other shares visible at \\server1 when browsing the network from any domain computer in the network.
While watching the user's desktop session, I observed that the offline files status indicates "Offline Files - Working Offline". During this condition, shares on the server are unreachable (appear to not exist at all). Navigating to \\server1 while this condition exists reveals that only "Users" is visible. Attempting to map a drive letter (or otherwise access any server1\share) fails. Pinging the server by name or IP works as normal during this "offline" event. My VNC session and VPN connection to the server are not interrupted during this event.
After what appears to be a random time, I can right-click on the offline files icon and choose synchronize and all server connections are restored (that is, browsing to \\server1 now shows all the shares available again.
Again, after what appears to be a random time, the "offline files - working offline" event reoccurs and the cycle repeats. (NOTE: I'm not asking about Offline Files...that is just a "landmark" to illustrate the larger problem and is symptomatic of the underyling problem, imo.)
There are no log entries that I can find either on the domain controller (server1) or the user's workstation that relate to this event.
Based on the above descripton, and answers to any clarifing questions experts may choose to ask, what's possibly going on here? Is it the computer account in the domain that's spontaneously losing/regaining trust? I'm open to any ideas that help me solve this issue!
