Hi Aleks, A custom connection, if you use the application server's IP adress, ony requires access to the server via port 1494. User authentication is done during the logon process. An application set also requires the client to be able to enumerate published applications. This means the client will have to be able to "talk" to the XML service (port 80) on one of the application servers, and, depending on farm configuration, also the XML service on the data collector. The default discovery mechanism for app servers is a DNS lookup on the hostname "ica". Otherwise a browser list of app servers will have to be defined for the ICA client and this still might still not work if the data collector isn't one of the servers visible. Data collector access aside, it's easy to embed a default browse list into a preconfigured client. PN enumeration should then work. An application set also requires authentication, so in your scenario passthrough authentication would have to be disabled. regards, Rick Ulrich Mack Volante Systems ________________________________ From: thin-bounce@xxxxxxxxxxxxx on behalf of Nikolic, Aleks Sent: Mon 11/10/2004 11:30 PM To: 'thin@xxxxxxxxxxxxx' Subject: [THIN] Authentication Custom ICA Connection/Application Set Hi, Our setup: NT 4 domain (WINS no DNS) W2K Servers Metaframe Xpa FR3 We have some users from another company who are resident in the same building as we are. They are on a different VLAN. The networkguru's created a switch accesslist which allows them to access 2 of our terminal servers. These TS host an application which they need. We used the Program Neighborhood to create the application set to our farm (we tried all types of connection settings: TCP/IP, TCP+HTTP etc). When we opened the application set, it tries to connect, nothing happens for a while, followed by a "1030 protocol error" or a "The Citrix server is not accepting connections" error. The next thing we tried was a to create a Custom ICA Connection directly to the application. Starting this connection directly gave a logon screen and worked immediately !!! That made me wonder why an applicationset to our farm doesn't work and a custom does! It seems that that the application set needs some kind of "broadcast" to connect? Any ideas on why the applicationset won't work and the custom does.?
