we have a farm of Citrix server (5) publishing QlikView Applications to users.
For some reasons 2 of 5 Citrix Servers cannot open Apps thru plugin.
When the user select an application and open with internet explorer plugin then he receives the attachment error message.
When the user open with Ajax, everything is working fine.
Furthermore, if user connected thru other Citrix server the apps is opening normaly.
Application Server Farm Windows 2003 x64,
Plugin Version 11 build 154
Internet Expolrer 8 with sites in trusted zone.
