Thanks for the information! I will send it on to the server administrator.
Another note though, through testing time and time again, I set up an Exchange profile for another user on the exchange server on their laptop, and the security warning did not come up. The error also did not occur on their desktop. Both systems were
using Windows Vista Home. The user requested the laptop be upgraded to Windows Vista Ultimate. Since the new version of Windows Vista Ultimate that was purchased included service pack 1, I was required to upgrade the existing installation of Windows Vista
Home to Service Pack 1 as well. After Service Pack 1 was installed on the Vista Home laptop, the security warning appeared. The desktop which was still running the version of Vista without Service Pack 1 did not have the security warning.
Also, I had to download the Service Pack 1 file from the Microsoft download website because the option to install it through Windows update was not available. Microsoft often blocks updates on systems where there is a known conflict.
This lead me to 2 conclusions: Service Pack 1 causes the error on the client side, and Microsoft must be aware of the problem. Thankfully, the security warning is more of a nuisance than a performance problem. I would hope that there will be a fix in the
future.
In the meantime, we will apply your solution. Thanks again!
If I am understanding this correctly the people with the problems just want the security alert to go away so there is a much easier way.
Go to the client computer that has the issue and look in \windows\system32\drivers\etc and you will find a file named hosts.
1) Backup the file
2)Open with notepad
3) Add this entry at the bottom: 127.0.0.1 autodiscover.yourdomainnamehere.com - This way it will send the search right back to the client computer and no more error
4) Save the file and your done - Now if you have 50 client computers you need to fix then just copy the edited file to the other clients and your problems are all solved without any server modifications necessary

Heh awesome, that's all -I- wanted.
I wasn't willing to go out and get another certificate just to make autodiscover work without a cert warning, and we didn't have the forethought to get a multi-host cert.

That worked nicely.
I had the same problem with one of our machines and appended the host file as prescribed. It appears to have fixed the problem but I was wondering if there were any adverse side effects to that entry in the host file?

Can I ask why you are going through so much work?

GUYS
why not simply goto your IE proxy exceptions and add these 2 exceptions
*.internaldomain.local
*.externaldomain.com
MIGHT HELP
