I'm trying to get some workgroup ISA firewall clients access to an Internet app using Citrix, and it fails. If I use the same workstations configured as members of the ISA server's domain, everything works fine when accessing the Internet application...but when configured as a workgroup machine...I get the following error in the client's application event log:

Event Type: Error
Event Source: WinSock Proxy Client
Event Category: None
Event ID: 1
Date: 7/11/2005
Time: 10:01:43 AM
User: N/A
Computer: BO00WCLIENT
Description:
Application [WFICA32.EXE]. Authentication was rejected by WinSock Proxy Server. Check the credentials for the account that is used for the process.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
Data:
0000: 05 00 00 00 ....

Can I build some sort of rule that will allow access through the ISA server for firewall client's to NOT USE the user/group/domain authentication that apparently is stopping this access? Again...things work fine when the client machine is a member of the same domain as the proxy server...but fails when in it's own workgroup. I've tried to build a client set for these machines...and allowed ALL IP and ALL Site and Content access for the client set...but that didn't help at all...

I'm considering configuring the client's as SNAT...but would like to see if there's a firewall client alternative for me. Thanks for your input.
