I am running Citrix Presentation Server 4.0 on a Windows 2003 server. All of my user's profiles are stored on this server as well. If I remote desktop into the actual server and set IE 7 as my default browser (on the Programs tab after selecting Tools - Internet Options in the browser) while I have an ICA session open, then HTML help works in a published application. But once I close the ICA session and then reopen it, IE 7 is no longer the default browser for my profile on the server. In other words, launching an ICA session removes the default browser for my profile. This is not just a problem for my profile. This affects all users on the server. I can also reproduce this issue on a Metaframe Presentation 4.5 server using different profiles and IE6. As a side note, there is not another browser installed on the server.
Can someone tell me how to keep the ICA session from wiping out my profile's default browser (other than forcing a registry setting through Group Policy)?
