Windows 7 - Sync Center Problem with Offline Files

I can't seem to figure out this issue. Hopefully someone can. My boss uses three computers, all running Windows 7 SP1 Professional. Her My Docs are redirected to a server share, and copied locally for offline use, via Offline Files. She often tells me that she thinks she is missing files and folders at any given point, using any one of the three computers (there's no pattern).

Now, when I check any of these computers, I see the little red X over the Sync Center icon. I'll manually run a sync, yet it fails each time on several old files. I can verify the files are present on each computer and the server, but yet it seems the Sync process doesn't agree. It also halts the sync, so no further files are sent.

How can I fix this? First, why doesn't the sync continue after an error and on a single file? Why would she be getting errors on a file that exists and is identical? The error is always "the specified network name is no longer available". I can restart the sync and it will fail on two more random older files.

The server is question is a plan fiel server running Windows 2008 R2. She is using the very same domain account on all three systems, and has local admin rights to all three system.

So far, I found a KB article that seems to describe my exact issue. I requested the hotfix and applied it to one of the systems for now.

Offline files synchronization may not finish on a computer that is running Windows 7 or Windows Server 2008 R2
