Fix for the issues faced while trying to mount VHD Files using VHDMount.exe, after applying the update 948515 on Virtual Server 2005 R2 SP1.
This update includes the fix for the issue described in article 953482: http://support.microsoft.com/kb/953482 .
The issue is seen after installing the update 948515 on a computer that is running Microsoft Virtual Server 2005 R2 Service Pack 1 (SP1). The user might experience problems while trying to mount Virtual Hard Disk (VHD) files by using the Vhdmount.exe tool. For example, on running the vhdmount /m vhd file command or the vhdmount /p vhd file command, the following error message may come:
The specified operation could not be completed as an unexpected error has occurred.
This issue occurs because the Vhdstor.sys driver is not successfully upgraded to version 1.1.623.0 after installing update 948515.
After installing this update, user will not encounter the aforementioned issue.
