Web Server certificates are checked against the root certificate list on the local machine. If a root certificate is not present, the client tries to use the information inside the certificate to check the cert against a public root certificate. The local root certificate list acts as something like a cache, so that the client don not need to check it all the time against the public root cert authorit.

The error message usually should show, what is the problem with the side. I.e. in Internet Eplorer is a red alert symbol, wher eyou can fetch the certificate information and possibly reason, why it is not accepted.

Reasons may be:
The root certificate is not present and the client can not check the cert over its own internet connection.
The certificate is in the list of "not trusted" certificates (in the local cert store). Use mmc and and the certificate snap in to check).

The root cert issuer is USERTrust Legacy Secure Server CA, I don't have it in my root cert list, but my clients can resolve the root cert via internet.

I see....
I guess if you compare the IE Settings wih a workign system, you may find out, what is the difference. At the end you brwoser settings doesn't allow you to access the site because of the certificate issue. Second, your computer seems not to be able to check the root certificate and/or to reach the certificate revocation list, if configured int he browser,.

First have a look in which security zone the site resides (File - Properties).
Then compare the setting of this security zone with a working system.
Also check the settings Tools - Options - Tab Enhanced
