We have a citrix server farm that I have updated 4 of the 5 servers to windows server 2003 standard. Now a few of the thin clients getting the error massage no citrix server configured at the specified address. On the connection configuration screen if we set it to “server” and hit refresh we get a list of servers, or set it to “applications” and hit refresh we get a list of applications. If we select a server or application and try to connect we get the error “no citrix server configured at the specified address”. This is happening in the same location where the same type of thin client is connecting with out a problem. This is in a wide area network and internet connection environment that we are seeing the problem, the local area network does not have this problem.
