Some people are getting '0x80040258/0x80004005' when PAU tries to find the first application in the farm.

--------------------------------------error code:

--------------------------------------error code:

In the log file you see that PAU succesfully connected to the farm and enumerated the servers.

There are two things that causing this:

-the datastore contains a partial/corrupted application

-mfcom doesn't handle this correctly and throws a exception.

Other Citrix management tools can operate normally, but they don't 'see' the corrupted application.

We have adressed this problem at Citrix, and awaiting a answer...
