Troublesome windows explorer running under Microsoft Server 2008 R2 X64 SP1 (Terminal Server)


I recently had an intermittent problem which was driving me nuts. A customer would scan to a central location (Another Server running Microsoft Server 2008 R2 X64 SP1) the file was delivered via a scanner which had SMB compatibility. This worked great however we had an intermittent problem where scanned files would take from 30seconds to 30 minutes to appear in the shared folder. I tried SMB tuning via all the documents I had, playing with network drivers etc. I finally gave up and posted on TechNet and found there where others with the same problem but no one seemed to know the answer!

Finally we agreed to log a call with Microsoft and of course as is with an intermittent problem it never happened when Microsoft was logged on. Typical.

We worked through several things with Microsoft, tuning of SMB, network card settings even went to different end user machines XP etc.

Finally after trying to install around 30 different hot fixes and tweaking left right and center we finally had an answer.


The patch that fixed the problem did not have our symptoms listed and seemed to be for a completely different issue altogether however it did update the shell32.dll

The Microsoft KB that fixes this issue is KB2525332 http://support.microsoft.com/kb/2525332

The TechNet forum thread is here where at the time of writing at least one other user has had success running by installing this KB

Hopefully this helps someone else as this is a total bitch of a problem!
