I have an interesting issue.  Users connect to Citrix Web Interface (CWI) in 
Australia and open Internet Explorer from Australian Citrix farm.  User then 
connects to another Citrix Web Interface in New Zealand (NZ) and tries to 
launch a Published App from NZ Citrix farm.   

Client - AU CWI - AU Internet Explorer - NZ CWI - NZ App 

When user clicks on any App, nothing happens.  If I change the Connection 
Preferences in the AU CWI to "Client for Java" the App launches.  The CWI in NZ 
is configured as a Trusted site.  What IE settings are required for ICA Web 
client to work?  Understand the configuration is not ideal as users are 
connecting to 2 CWI's but they don't have the ability to go straight to NZ CWI, 
connection must pass through Australian CWI. I have installed the latest ICA 
Web client on the XenApp 4.5 server in Australia that hosts Internet Explorer 

Any assistance appreciated

So basically any user on and internet connected device can type in user names 
and passwords?  So, a crafty person can launch a DOS attack and lock out

nope its configured as a session policy.i argued that its a bit silly as the 
user has already authenticated, but the client was advised (at some point) by 
citrix that pre auth is more difficult to troubleshoot when clients are logging 
in (the fun error codes the netscaler spits out) and they have many multiple 
people connecting from many different devices
so they were adament they wanted a scan / reg scan after the user name and

Correct me if I'm wrong, but wouldn't that be  a pre-auth policy?

Greetings thin list legends!long time no email!
Quick one.I have a single Netscaler Access Gateway with one post auth session 
policy which points them to storefront.

It runs an single EPA check for a registry key for the domain membership.If it 
fails the registry check however its 'defaulting' to a the client choices page 
and starts running an SSL VPN!?!

Ive checked all advanced settings and the global settings - and there is 
literally nothing set to create this?Any idea how to set a policy so that 'If 
your EPA scan fails' the system just denies access? or even another policy 
which would direct them to a web server that doesnt exist or really ANYTHING 
other than starting a FULL SSL VPN!! :)

I hope everyone is well and looking forward to the holidays!All the best for 
xmas and the new year.
