Accessing Load Balanced Farm through AAC , in the Advanced Access Control / Citrix Access Gateway forum on BrianMadden.com

Hi,

I've recently implemented a second Citrix server into my farm. It now consists of 2 PS 4.5 servers load balanced via default Load Balancer rule. Load balancing on the internal LAN works fine whereas accessing the farm through my CAG/AAC I receive an error stating "Protocol Driver Error" from time to time.

I added the corresponding Citrix PS named "citrix2" to the farm settings in my AAC configuration as well as in the WI configuration. What did I miss?

Supplement:

After adjusting the firewall settings the error still occurs. First it seemed to have been a firewall misconfiguration. But now I'm not so sure anymore. Now I've been digging deeper. The CAG log files states the following 3 entries as soon as the error "Cannot connect to the Citrix XenApp server. Protocol driver error" appears:

(09/24/08 15:20:58):L10:LOGSVRE:3041:98311:server:sta_proto: :sta.c:994:SESSINFO:33::validate_ticket_format failed for ticket ;40;STAB93D51106F3C;33BB736278788BFBF06185D4C4EB2A05:

As the log file states a problem including my STA I checked its functionality by using statest.exe on both citrix servers. Ticket issuing works fine as well as validating.

Any idea?
