This is not really an ISA Server issue. But I have not been able to find an answer anywhere else so I thought I would try here.
I have an Enterprise CA setup that is handing out all my certificates for everything. Workstations, users, published web sites, etc.
I want to request certificates from my CA through ActiveSync for my smartphones. When I click on the "Get Certificates" option I can see my certificates in Active Directory. However when I click on the Enroll button and then click Continue on the smartphone it says "certificate enrollment could not be completed....".
I can get a certificate fine through the web enrollment but this does not work.
I'm having some odd problems with VPN using PPTP. The VPN will connect fine but if I try to browse a server it says that I am not authorized. I read somewhere on Microsofts technet website that using client certificates and L2TP for VPN gets rid of this problem. So I want to load a client certificate for VPN authentication.
I manually loaded a CA certificate and a certificate for my OWA website for use with Exchnange ActiveSync but those certificates aren't helping with the VPN problem.
The ISA server is a domain member. And I have the VPN setup using the dial-up setting and PPTP. There is no prompt when the VPN connects because the users credentials are entered in the VPN settings and the VPN connection itself connects fine. But when I connect to a server with the File Explorer to browse files I am prompted for user credentials again, which I don't really mind because you can save the user credentials the first time you connect. The problem is that when I get the prompt when connecting to the server I enter the user credentials and it tells me "Access Denied". So I have a VPN connection but I can't do anything with it.
