After stopping the Citrix RSSH services the following error is received when viewing the Server Status > Server Script Host > Scripts
“Retrieving the COM class factory for component with CLSID x failed due to the following error: 800703fa”
Stop IIS AND Stop the Edgesight RSSH Services (both)
Start IIS; Start RSSH Services
I had all of this from http://support.citrix.com/article/CTX125410, I even restarted Citrix services. But the clincher that you gave me was restarting IIS.
