I've looked at that post. When I set SSLEngine on I get a squid message saying (111) Connection refused. Also, just the website on the server without ssl (http port 80) will not work.
With SSLEngine off, I do get the IE certificate message, then after accepting, I get the Internal Server Error.
Here are the items you asked for:
/service/httpd-admin: run (pid 4663) 84092 seconds, normally down
/service/httpd-e-smith: run (pid 4791) 82926 seconds, normally down
[root@iserver ~]# cat /var/log/httpd/admin_error_log

The message log does not have any strange errors in it. It is very large, I can post if you think it will help. I did not change the domain name durning the switch. I have since tried changing it in hopes of fixing the problem, (changed name, reboot the server and tried with no luck). Then changed it back to the current (real) domain name.
