Webclient does not support concurrent I/O operations


Got this error on a Windows Server 2008 R2 with all updates.

I first downloaded some service packs for the SharePoint Foundation version. This was completed successfully. When those where done I selected the "Service pack 1 for SharePoint foundation..." option and started those downloads. After a few seconds the attached error occurred.

It continued downloading while the error was on the screen. The only SP1 language pack that failed was the dutch version. (see attached screenshot)

Starting the download again with only the "SP foundation SP1 - Dutch" selected does work.
