what kind of certificate is it? A thrid party one?

When you go to mmc certificates / computer/local store and check the certificate you have imported does it have a private key?

If you go to the last tab can u go back to the root certifictae?
i just noticed u specified digicert certificate. are you sure you imported it in the computer certificate store? not the user?

3rd party cert from digicert

the digi cert certificates dont have private keys key has private keys on both the exchange and the TMG

i have installed them on the local computer yes not the user

I went to exchange opend mmc and exported the certificate including all certificates in the path
then i imported and now on the TMG server see screen 1 then screen 2 says i dont have the private keys for the digicert stuff, do i need them, is that why its untrusted?

ok i looked on the exchange server and looked at where all the certs where, i then did a export of my cert with .pfx included private keys and extended properties and included all certs with it

then imported it on the firewall and let wizard choose where to place the certificates
i then compared the exchange mmc to the tmg mmc and there was still some differences, on the tmg there wasnt a certificate in the third party trusted root and there was only 1 cert in the intermidiate as opposed to 2 on the exchange

so i exported them and imported them into the tmg went to the login page appears saying its secure but when i put in credentials and log in i get

page cannot be displayed
Error Code: 500 Internal Server Error. The certificate chain was issued by an authority that is not trusted. (-2146893019)

what else could i have done wrong?
