Hi John,
Had a simmilar problem and it turned out that the CSG box was not using DNS
and did not know where to find the FQDN, fixed that and got it to work once
the Firewall people added a few new rules.
Cheers,
Shane
> I'm having an issue with Citrix Secure gateway that is driving me bonkers. I
have CSG and the Web Interface on the same server in our DMZ. Clients can
connect via HTTPS to the CSG server and be proxied to the Web Interface where
they can log in without any problems. The problem occurs when the selects an
application and clicks the icon. The ICA client window pops up that is titled
'Connecting to [application name]' and then BAM - the error reads "Cannot load
the ICA client drivers [Error 1034: Communication I/O error]"

> I installed the new Verisign intermediate root certificate.
> I reissued our Verisign server cert.
> I have restarted the server more times than I can remember...

forums and have seen that this error has been happening for others, but none
of the proposed solutions there were applicable to my setup.
