TFS 2010 Get operation fails periodically on large files (> 1MB)

Question

Occasionally I get an error from my builds with the following error message:

[Large File Name]: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

One or more errors occurred while performing a Get operation.

Everytime this happens, the file is always over 1MB in size.

The setup is TFS 2010 with a Build Agent that is a VMWare Virtual Machine running Windows Server 2003 R2.

As I mentioned earlier this does not happen all the time (maybe one out of ten times) so I hoping that there is a configuration setting I can alter to fix this.

Answer 1

From you description above, I assume it is Windows Server 2008 R2, and not 2003. If so, this is a known issue with large files and you can find a blog entry describing the issue:

Microsoft has released a QFE that you would need to apply to your App Server running TFS 2010. A link to request this QFE is in the blog entry, about in the middle.
