Whenever I try to connect to the CRM server using http://crm/ from a
workstation I get the error (after 3 attempts):

HTTP Error 401.1 - Unauthorized: Access is denied

Oddly enough, when I enter in the internal IP address of the server,
i.e. http://192.168.16.100, then it loads from the workstations fine. (I
provide my Active Directory username and password).

But when I enter the machine name, dynamics, it prompts for a log-in
three times and then refuses access to the server. Also, when I
connect to http://crm from the server itself, it works fine.

How can I solve this problem?

Thank you.

Hi

I had the same problem. It can be that you did not use Windows
Authentication in Internet Explorer. Try add to Secure Sites the
domain http://crm and also verifiy Secure Sites Security Zone has
enabled Windows Authentication.

Greetings,

Thomas

You may want to look it the correct SPN's have been set

download it here:
http://technet2.microsoft.com/WindowsServer/en/library/b3a029a1-7ff0-4f6f-87d2-f2e70294a5761033.mspx

use "setspn -l <servername>" to list all the spn's. There should be an entry
"http/crm". if this isn't there use "setspn -a http/crm <servername>" to add
it.
Note that the above applies if you use a system account (Local system,
network service, local service) to run the crm apppool. If you use a user
account you must use the useraccount in the commands instead of the
servername.
