Unable to Connect to Exchange 2010 - Cert Error 80072F06

Hi,

Thanks for your reply. I ended up coming to the same conclusion about it being a problem with the CN in the cert. It's weird because if you viewed the cert, you would see that it did have a matching CN. However, browsers (Firefox, IE, and Chrome) pointed
to OWA all reported a problem with the cert -- both due to not trusting the CA (it was self-signed) and due to a name mismatch.

This cert did show the proper CN when you viewed the cert, so the browser error was odd, but the CN address was missing from the list of Alternate Names, which is apparently what the browser (and WP7) look at to determine whether or not a site is valid for
the cert. Anyway, the Exchange admin issued a new cert and included the CN in the AN list and all was good.

Since I had previously installed the root cert to my WP7, I was able to immediately set up my Exchange 2010 account on the phone.

Someone else in my office has an Android phone, and he had problems with the cert too. But for him, he just checked the "Accept all certs" box, and he was good to go. It would be great if MS offered that in cases like this, where I, the user, explicitly
trust the cert in question.

tl;dr +1 rep to Tobias D. It was a problem with the CN. Issued new cert to Exchange server and all is good.

 

Creating a self-signed cert and trusting it for windows RDP (no domain)

Selecting 'yes' and checking the box for 'Don't ask me again ...' will accept the self signed certificate and not prompt you to approve that certificate again.

So yes - a cert was generated for you, it's perfectly fine to continue using that in this usage scenario, and you don't need to do anything else.

For personal use like this there is no need to pursue a 'real' cert signed by a CA, but opinions (and paranoia levels) vary. It's getting cheaper and easier to get legitimate certs, (see let's encrypt), but it's a bit of a hurdle to use those for RDP still.

One note: If you are connecting to this computer over the same VPN link from the same remote computer, and you have selected to trust the cert and 'do not show me again', but at some time in the future you are prompted again, that is when you should be somewhat concerned. That is how a man in the middle attack would present itself.

You can view the certificates from remote machines that you've trusted, implicitly due to being issued by a CA windows trusts or explicitly like in the case of this rdp cert using the cert mmc plugin described here

 

Vpn ( trusted Vpn)

Hi everyone.
I am not an expert about Vpn and that's why I would like to know if someone could list me a few trusted Vpns, I would really appreciate any suggestion/ advice.

Thanks.
