Dear fount of all knowledge, After installing PSE400W2K3R04, PSE400R04W2K3001, 002, 007, 011 and 039 - it seems that Citrix Administrators from other domain must be specified explicitly by name, and not by group membership. For example - the servers in the farm belong to DOMAIN2. Metaframe Administrators shows: DOMAIN1\joe.bloggs DOMAIN1\Domain Admins Only joe.bloggs will be able to use the Presentation Server Console, or run qfarm.exe If jane.doe (a member of Domain Admins) tries to run, say qfarm /zone, she will see "You must be a Citrix administrator to run this application." DOMAIN2 trusts DOMAIN1 (external, non-transitive). This only seems to be affecting the server which is the Data Collectory / Primary Farm Metric server. Any ideas? I've been trying to troubleshoot from an AD perspective, but can't see anything wrong with the data collector's configuration or ability to communicate with the domain. -- AdamT "A casual stroll through the lunatic asylum shows that faith does not prove anything." - Nietzsche ************************************************ For Archives, RSS, to Unsubscribe, Subscribe or set Digest or Vacation mode use the below link: //www.freelists.org/list/thin ************************************************
