Problem Definition:

While booting, a Citrix XenApp Server prompts for a chkdsk.  However, when Windows attempts to run the chkdks, the chkdsk fails with the following error:


"Cannot open volume for direct access.  Autochk cannot run due to an error caused by a recently installed software package."


Event ID 98 is also logged in the Windows System Event Viewer.


The Citrix virtual delivery agent disables chkdsk in the pre-boot environment by default.  When an chkdsk is required this registry setting RE-enables the chkdsk in the pre-boot environment for the next boot cycle.


On the affected Citrix Server, open the registry editor, and set the following:




Name: Start

Value: 4

Restart the Citrix Server, and the chkdsk will now run.
