Juniper SA publish custom ICA
I have deployed more Juniper SA 2000 appliance and in overall I am pleased with the working of the appliance. Sometimes we have minor problems when publishing ICA sessions through the appliance.
My colleagues have customers with connection problems, where suddenly the ICA sessions get disconnected and we cannot find the cause of these disconnects. Load balancing through the SA is also “hard” to configure. You have to define a custom ICA file and add the correct parameters for load balancing the sessions. In our opinion the Juniper SA appliance is a decent SSL VPN appliance, but not suitable for native Citrix environments. In native Citrix environments we prefer Citrix Secure Gateway or Citrix Access Gateway.
Now I recently noticed something strange with the Juniper SA. I am publishing a ICA session with a custom ICA file. The firmware of the Juniper is 5.5R2.1. Now I noticed that it isn’t possible to connect from a Windows 2003 server. When trying to connect you will receive the following error message:
I checked the compatible platforms for Secure Terminal Access and Terminal Services for the 5.5 firmware and yes……Windows 2003 server isn’t supported!!!
Looking at the compatible platform for the latest firmware (6.2) Windows 2003 is supported for Secure Terminal Access and Terminal Services. So I hear you think: JUST UPGRADE THE DAM THING, but I don’t know the impact on the current configuration and published services.
I guess it would be great to check if it is possible to “hack” a Windows 2003 server and adjust the security features of the server. Because I guess that the security policies, introduced in Windows 2003 server, are the cause of not connecting the ICA session.
I hope: TO BE CONTINUED…..
