SBS2003 and Outlook Anywhere

I have many SBS 2003 installs and Outlook RPC over HTTPS has worked flawslessly for years on many different client systems (XP, Vista and Win 7).  Recently the Win 7 SP1 machines cannot connect with the credintals prompt.  I have the cert installed and do not get the SSL warning on OWA or RWW.  If I install XP Mode on the Windows 7 box, which I had to do to get it to work, it works OK.

I have 30 or machines (Windows 7 Home Premium, Vista and XP) all doing this only recently am I getting this problem.  I know full well that getting a public cert may help, but can anyone help me understand why this happening and how to fix it?

Thanks,

Joe

Are you using a different version of Outlook on the Win 7 machines?

Check to see if in the exchange proxy settings if you have autoconfig, basic, or NTLM authentication.  Make sure it is not set for autoconfig if you are using a self signed cert.  

Also is the cert one from your networks Cert authority or the one that was initialy installed with the server?  If is is, then try creating a cert from your DC.

I have been trying Outlook 2003, Outlook 2007 and Outlook 2010 and all of them fail.  To this server I have other xp machines doing Outlook Anywhere and this is happening on one other server.  

I have basic authentication.

The cert is the one that was initially installed and expires in two years.

Thanks,

Joe

It is a cert issue I am sure and Exchange Connectivity fails on the self signed cert with Win 7 sp1, but on same machine XP it works OK.

A 3rd party cert will solve the problem....but you may be able to get around it. Did you install the certificate from the RWW screen?

You can get inexpensive 3rd party certs for utilitarian purposes such as this from namecheap.com
