Written by I experienced a very strange issue on a Windows 2008 SP1 R2 Terminal Server. When a user attached an attachment from a network share in Outlook 2010, a dialog box came up stating the attachment was downloading. Outlook was slow, and both Outlook and Explorer.exe was getting “application errors”.
The server was slower and slower, and events like this showed up in the log:
EVENT ID:50 TermDD
The RDP protocol component X.224 detected an error in the protocol stream and has disconnected the client.
EVENT ID: 56 TermDD
The RDP protocol component X.224 detected an error in the protocol stream and has disconnected the client.
EVENT ID: 7011 Service Control Manager
A timeout (30000 milliseconds) was reached while waiting for a transaction response from the “servicename”
The only solution was to force “dirty shutdown”.
Things I tried:
- Installed http://support.microsoft.com/kb/2465772
- Latest patches/firmware was installed
- Antivirus – Disabled
- Many other thingsJ
Finally I checked TCP offloading, this was already turned off. Just in case I also did:
- netsh int tcp set global chimney=disabled
- netsh int tcp set global rss=disabled
- netsh int tcp set global autotuninglevel=disabled
And guess what. That did the trickJ I turned the settings on again, and once again the server crashed. Turned it off again, and attachments worked perfectly.
Other notes:
- Physical server (IBM System x3550 M3 7944 K3G
- Windows 2008 R2 SP1, Office 2010 SP1
- PDF attachment was the only attachment type I tried
