Push on exchange is not working - Seems to be IIS/Active Sync

We have a 2003 server running Exchange 2000 (6.5 SP2).
Push was enabled a few weeks ago and has been working ok since.
Today mobiles are not syncing mail.

We can connect to the server using : http://servername/oma - works ok

Create a test account with mailbox and run the activesync test in the Microsoft test site.
See what that flags and post the errors here for more help.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

We are not using SSL for this by the way

Run the test again but check the Ignore Trust for SSL checkbox

Checked this but get the same results with it checked and unchecked
See the site is in beta - maybe this flag does not work?

DCMBSCommented:
I have used this before and the flag works.  It normally progresses on to test the connection despite the certificate failure.

DCMBSCommented:
At this stage I would try a reboot of the exhcange server.  Have you tried this?

Do you have a cert for sonicwall?

DCMBSCommented:
Its a bit of of a puzzle as to why it isn't progressing beyond the certificate tests. I have used this before on sites that don't use certificates and it usually carries out a further set of connectivity tests that don't seem to be happening for you.  As I said previously, I would try a server reboot.  have you tried this yet?
