I recently came across the following error message while updating the properties of a vDisk on Citrix Provisioning Services 6.1. I tried to update the version from Maintenance to Production.
“An unexpected MAPI error occurred.” “Failed to map vDisk. No Driver.”
I found a way to update the properties of the vDisk with the following procedure:
Open the Citrix Provisioning Services console and open the vDisk store
Right click on the vDisk and select Properties
Go to the Microsoft Volume Licensing tab and set the license management to None. Click OK.
Now, right-click on the vDisk again and select Versions.
Click Promote.
Select Production –> Imidiately or do as you see fit.
Now you can put back the properties of the vDisk to have KMS license management again:
