Program Neighborhood Agent initial logon and repeated logoff issues.
Posted on 2008-06-23
I'm deploying Citrix Program Neighborhood Agent Application Access to ~200 user's across 27 locations. My project is currently on hold because 12 of our sites connect via 1.5Mbps up /1.5Mbps down VPN cable connections from which the first 2 sites have been having extensive server connection and access stability issues. Below is the to interrelated issues I face. I believe the connections to be as stable as physically possible do to the extensive connection testing I've done.
I suspect routing issues to be the root of the issue or maybe GPO or Citrix settings. Please review the user experience scanrios below and let me know where I should concentrate my efforts toward resolution.
From the remote locations when you boot up a machine then logon to Active Directory the user's shared drives will be assigned appropriately so I know AD is talking and the logon .bat file is working.
The Citrix Program Neighborhood Agent running in the lower right hand corner of the screen will report that it is "Reading Config from X.X.X.X (IP Address) or it will say from the name of the server X.X.X.org depending on how we have typed the server path in the PNA Server URL box.
The following error will then appear: "Program Neighborhood Agent could not contact the server. Please check your Network connection."
The user's then Right Click on the Program Neighborhood Agent and choose change server. They Leave the info as it appears in the Server Address field then they click the Update button.
The Citrix Program Neighborhood Agent active directory domain logon screen then appears. They enter their AD user name and password then the user's applications will populate on the destop and will start if clicked on.
If you reboot the machine shortly after doing this process you do not have to perform the change server process in Citrix.
Periodically the Citrix PNA will logoff and thier application icons will disappear from off the desktop. The user's only notice this when they minimize whatever they are currently in and attempt to load another application. The user's may have 2 or more Citrix application sessions running and be actively using these applications with no interuptions when the PNA logs off.
In order to get access to thier other Citrix application icons the user's then perform the same change server process using the PNA interface running in the lower right hand corner of the screen. Alternatively if the Logon option is available they are able to click on it and the icons will reappear.
The entire Citrix farm is located within the same IP network in our data center and goes through the same switch that the AD and File servers are connected to. Although the AD and File server's are on a different IP network.
In the initial logon scenario above it appears that the breakdown is in client's initial communication with the Web Interface Server and or the WI server to its "XML Broker" and I'll begin looking into that with our Network Administrator.
For the periodic logoff's I'm not sure why this is occuring other then if for some reason the communications are being interupted with the Presentation servers but the question of why the sessions that are started are not being interupted. It is only the PNA's status that is changing.
The VPN is being established between the remote office and the Data Center through Cisco gear. I can give further details on the connections once I meet with my Network Administrator.
Any insights will be greatly appreciated!
