SBS2003 - Can not OWA remote access get IIS error

We think this might have something to do with a certificate a 3rd party tech created on the server.

Here is a screen shot of what we now get when we try to remote in.

What type of certificate did you have on the system before the tech struck?   I would reboot the server just to make sure you are dealing with a stable system.   Then if I had an SSL on the server originally, I'd reinstall it.   If not, I'd go to GoDaddy and get one of their introductory discounted SSLs (take it out to the maximum number of years they'd sell it to me at a discount price) and install a new certificate.

Based on the error screenshot you have provided; it seems on the default web site where Exchange specific virtual directories are created; there is IP restriction is configured either on the website or virtual directory within website. You can get it checked with below steps;

Open IIS Manager -> Expand Web Sites -> open properties of Default Web Site -> Security ->  Edit IP Address and domain name restriction

I have no idea how those restrictions got there. I suspect whatever the third party tech did (I was not involved).   I removed the restrictions and all is well.
