Question:
I migrated from 14.0 to 17.0. If I select now in the Administration Tab >xFlow Analyst Interface>General, the content will not be loaded and I get an "AHD04400:Argument error". How can this be solved?
Environment:
CA Service Desk Manager 14.1
CA Service Desk Manager 17.0
Answer:
You need to edit all web.cfg files in the samples\pdmconf directory, and in the bopcfg\www directory on ALL servers (Primary and Secondaries or for an AA environment the Background, Standby and all Application servers) to update the following:

Find:
Windows_SecureValidator.FactoryString ^[A-Za-z_:]*$

Change to:
Windows_SecureValidator.FactoryString ^[A-Za-z0-9_:]*$

You have to restart the services on all boxes afterwards.
