I have been diggind around for a solution to this but have not found one that sticks as of yet.
I have recently changed laptops to a machine running Vista Ultimate. I am attempting to connect to a Citrix server running Presentation Server 4.0 with the latest hotfix rollup package on a Server 2003. Currently, we conect via straight custom ICA connection without using the web interface. I know I need to upgrade both the version and the connection method, but for a small firm with proprietary software I have to move somewhat slowly with upgrades and everyone but me is having no issues.
With both laptops side by side on my home network, the XP machine connects fine and the Vista machine gives me the errror that there is no Citrix server at the specified address. I have listed both the IP address of the virtual IP on the firewall and the FQDN address in my trusted sites in IE7 and given booth ICA.32 and pn.exe full access on my Mcafee firewall. This made it work for a couple of days but now I am getting the error again.
