[THIN] After PSE400W2K3R06 : MPSError type="IMA"0x80000032

Hi,

Tested last week PSE400W2K3R06 on a test server and everything went ok so
rolled out yesterday PSE400W2K3R06 in production (Windows 2003 SP2 , PS 4.0
farm), but now a lot of people only see a few of all published applications
they are granted for (via Program Neighborhood client). WebInterface 4.5
even does not show any application. Looking at the WI servers I found
following error messages:

"The XML document sent by the Citrix servers could not be processed because
it contains invalid XML. This message was reported from the XML Service at
address "http://<server ip>:80/scripts/wpnbr.dll
http://com.citrix.xml.NFuseProtocol.RequestAppData". This XML Service could
not be contacted and will be temporarily removed from the list of active
services. Log ID: 2578550e"

And detail from networksnif on WI server:

Recreating the local host cache is not working. A restore of the data store
before the PSE400W2K3R06 did not work either.
Any ideas what is the culprit?
