Windows 7: VPN and connecting to exchange server with rpc over https issue

nworker · 29 Sep 2011

Sorry if this is in the wrong area but since its related to so many things (exchange, network, dns, windows 7) I thought I would start here.

We have an issue with all of our Windows 7 remote users where they cannot connect to our hosted exchange server while connected VPN (PPTP or SSTP).

Our email is hosted at Rackspace.com. Users connect to the exchange server using RPC over HTTPS. All of that works great over the Internet.

If the a Windows 7 user connects to our VPN (Windows routing and remote access server in our corp. office) first and then tries to get into Outlook, it continually prompts for the password and never connects.

If you disconnect from the VPN, email connects up and works great. If you get into email first and then connect to VPN, some users work fine. Others say it works for a while and then it prompts for password. Same results using the VPN property "use remote default gateway" or not. We usually uncheck for the user so they can use their own Internet.

We have no problems with Windows XP users. Email works fine with VPN in any order on XP. This is a new issue since we started issuing Windows 7 laptops.

Wondering if you have come across anything like this?

autodiscover resolves to Rackspace like it should.

Rackspace says they have not heard of this problem.

Thanks
