It can get a lot more trusted than that. :-)
Your cert is probably issued off the Federal Bridge Certificate Authority,
and I would guess that the state one is issued off some internal CA for the
State of WV. Neither of those is in the trusted root store in Windows, and
that is what is causing the error that you see.
Since I doubt you can influence the DoD to get their certs installed in the
root store, you can do it yourself using this method:
1. Launch Internet Explorer as an administrator. To do that, right-click the
Internet Explorer icon and select "Run as administrator..."
2. Navigate to the site that is showing the error.
3. When you see the "There is a problem with this website's security
certificate" message, click the text that says "Continue to this website (not

of that is a little red shield with an X through it and the text "Certificate

5. Click the "Certification Path" tab
6. Select the top-most certificate you see there and click "View
Certificate" If there is only one certificate there (unlikely) then click the
General tab again.
7. In the General tab click the "Install Certificate..." button.
8. Click "Next >" twice and then Finish. Click OK.
9. Close Internet Explorer and reopen it normally. When you now navigate to
the site you will no longer get this warning.
