We are having problems launching a Citrix application which has been provided to us by an external company.
We have a .ica which makes a direct connection to a server. However, the ISA server which acts as our Web Proxy is failing to forward the traffic and we are receiving Failed Connection Attempt - Status Code 59 - an unexpected network error occurred. The logs are only reporting HTTP traffic.
However, I have tried opening ports 1484 and 2598 on the ISA Firewall and we already have a rule in place to allow HTTP and HTTPS traffic.
This connects fine using an ADSL connection away from the ISA server.
Has anyone else come across similar problems or even better a solution which will allow us to get the traffic through the ISA Firewall?
