Using IE 7 getting certificate errors.

Added trusted root certificate and corrected a couple of cert issues with two servers. IE was all happy.

Now, trying to do the same cert repair on the other servers, in the same tree, get an certificate warning. When accepting the cert and looking at the particulars of the error, tells me "this certificate cannot be verified up to a trusted certified authority"

Have created new certs for these servers. I even re exported the root cert and reimported that into IE. The servers I did yesterday still work, those I have tried since those, last evening and today, continue to thumb their nose(s) at me. Boy, I hate that.
