this
is a known issue due to change of functionality with SP2. It has to do
with how IE now handles MIME types from the server. Citrix has stated
that they will come up with a fix for this (no time frame given).
Try this workaround:
When you are selecting an app to launch, right click and 'save target
as'. This will download the 'launch.ica' file for the application
you want to launch. Then after it downloads, click on 'open' and the
application will launch.
Another workaround is to disable this new MIME-handling logic, more
about this below.
In Windows XP Service Pack 2, Internet Explorer follows stricter
rules that are designed to reduce the attack surface for spoofing
the Internet Explorer MIME-handling logic.
Web servers that do not include the correct Content-Type header with
their files and that use non-standard file name extensions for HTML
pages now have their pages rendered as plain text rather than HTML.
Web servers needs to be configured to use the correct Content-Type
headers. Web developers must change their Web servers to host files,
using consistent headers and file name extensions.
You can disable this new behavior on your local computer with some
registry settings.
