Sounds like clients are reverting to the default of TCP/IP + HTTP. ICA clients browse the network for ICA services such published applications, Metaframe servers and server farms over TCP port 80 if using TCP/IP + HTTP. If using TCP/IP then clients are bowsing using UDP port 1604. The newer method is to use TCP/IP + HTTP since UDP is less secure then TCP. -Mike -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On Behalf Of Steve Parr Sent: Wednesday, August 24, 2005 9:24 AM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] Application Set details on some Citrix ICA clients getting lost Citrix ICA Client version 7.1 - some remote sites may have clients running 7.0. MF XP FR3 At one remote site in particular seems like Citrix clients are losing Application set details such as 'server ip address' and default protocol of TCP/ip seems to fall back to TCP/IP + HTTP. Is there are a known issue or perhaps the IT folk who are setting up the clients are missing something. I don't believe it is an issue of some users logging in under diff. Windows users profiles on pc or laptop and losing client settings so something else most likely and have not seen this happening at any of the other sites.
