What changes are needed for Activesync via ISA 2006 when migrating from SBS 2003 to SBS 2011

I'm in the midst of migrating from SBS 2003 to SBS 2011 and am having a problem getting ActiveSync to work via ISA 2006.  I had this working with a public cert on SBS 2003, but can't seem to get it to work against the new 2011 server which, as you might imagine, is painful given we rely on iPhones for e-mail.  Some factoids:

- SBS 2011 is patched current
- ISA 2006 is not patched current
- Cert is from godaddy.  I moved the original key from SBS 2003 to SBS 2011 and bound to port 443 on the IIS/ActiveSync folder

I'm kind of at a loss and the natives are getting restless - please help.

I'd start with a simple test using a dummy (working) domain account and the https://www.testexchangeconnectivity.com/. Also use logging on ISA to see what happens. After the test is over, disable the used account.

Doesn't work. We spent weeks trying to get ISA 2006 working with SBS 2011. There are differences in the key protocols that ISA blocks.

We ended up replacing it with a Cisco.

Thanks to both for the quick response.  Do you know if SP1 fixes the issue?  Also, fair to assume TMG will work properly?
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

I'm not able to say if SP1 fixes or not. In any case SP1 should be applied. TMG should work properly since it is "new" and it is expected to work properly with SBS 2011. I always suppose you are talking of ISA 2006 or TMG installed on a dedicated server, not on the SBS server itself.

Current TMG will be fine.

ISA 2006 in any flavour is a no-go.
