Since there's no device actively manipulating the stream between the users and the XenApp server, can the oversees users telnet to the server on TCP 1494 (or 2598 if you're using Session Reliability)? By the way, are the servers that work and the one that doesn't both on the same XenApp version? We have trouble with the newer XenApp clients (receivers) connecting to PS v4 and older servers.

(2) Do you initiate the connection through Web Interface, StoreFront, just an ICA file, etc.?

There is no Citrix XenApp server configured on the specified address. Hi Have a strange issue where overseas users are getting the following error when trying to connect to 1 Citrix XenApp 4.5 server: Unable to launch your Application. Contact your help desk with the following information: Cannot connect to the Citrix XenApp Server. There is no Citrix XenApp server configured on the specified address. Strange thing is I can connect to the server without any issues. I'm testing internally. The overseas team are also testing on the internal network (no DMZ's in the picture). They can connect to other Citrix Servers, just one server is causing the above issue. Any ideas on how to troubleshoot? Works for me internally so not sure whats happening. Only difference is IP range.. Should I reinstall Citrix on the one server thats playing up? Thanks Ang This message and any attachments are solely for the use of intended recipients.
