There are known problems with SL & Citrix
As I know next to nothing about Citrix I'll have to leave you with the Snow Leopard compatibility site, hope you get some ideas from there.
I have a similar problem though I am a new macbook (and snow leopard) user. I previously used PC and windows with no problem to connecting citrix. Since I bought the new macbook and snow leopard, I am unable to connect to citrix. I need to get onto citrix for work purposes. This is really frustrating and if I had known that this is such a problem I would not have bought the mac.
Anyway, every time I try to connect to citrix using my new macbook, an error message comes up which states:
The security certificate "OU=www.verisign com/CPS Incorp.by Ref. LIABILITY LTD. (c)97 Verisign, OU=Verisign International Server CA - Class 3, OU=Verisign\, Inc.,O=Verisign Trust Network" is not suitable for use in SSL connections. Reason: Unsuitable Netscape Usage Extension field.
Can anyone help?
I use Citrix daily for work, and haven't experienced any problems since upgrading to Snow Leopard.
I googled your error and found a similar message mentioned on the Citrix Knowledge Centre (CTX113002). Its only real recommendation was to install the latest client.
Are you using v11 Citrix Online Plug-in? (seems to be their new name for the client)
A similar post on this Citrix error when upgrading to Leopard:
Are you connecting via Java Client using Citrix web access? Have you tried Firefox if currently using Safari? Or do you have the option of using Native/Local Client instead of the Java Client?
I'm having the same error: "please make sure the destination server is listening on port  and try again" with lots of letters and number in between. This happens when I try to access my hospital database via Citrix.
Oddly when I first upgraded to Snow leopard, it didn't occur till I installed Adobe CS4 Master collection. I restored the system (using time machine) to a previous time and error resolved. So it had to do something with my photoshop installation. I have two computers with snow leopard and both had the same error after Adobe Master collection install.
I tried Adobe photoshop elements and it again caused the same error. I don't understand at all. It takes a while to restore the system back so I'm really getting tired of it. I will not install any Adobe product till there is a fix to this.
If you have a solution, let me know.
I called my hospital's tech support and the following solution worked for me.
Close Safari and other browsers.
Go to Applications > Utilities > Java Preferences
Under 'General' Tab hit 'Restore Defaults' for both Java applications and Java Applet plugin.
Then click 'Network' Tab and hit 'Delete Files' button at the bottom.
Wait for it to finish. Then open your Citrix or Safari and error would not happen.
Hope it helps.
