PVS: An unexpected MAPI error occurred

A lovely error Citrix Provisioning Services (PVS)  "An unexpected MAPI error occurred" error. Fortunately, Jeff found the fix and shared it here.  This is a bug in PVS 5.6.

Solution: In short, when you edit the properties of the PVS vDisk, set the disk status to Standard and select “MAK” on the Licensing TAB and press OK. Now you will not receive the error. Then set it back to KMS and click Ok.

ExecuteNonQuery Failed for database

This error happened to us today as we were updating our XenDesktop 5.5 environment to 5.6.  I swear the DBAs changed the perms on us but found out the SQL database failed to the mirrored site.  Anyway it was an easy fix and Citrix even had an article...just fail them back. 

Lesson learned:  If you are usign SQL mirroring, make sure the SQL databases are on the primary node PLUS get some scripts in place to auto-fail back.
