I go into the Internet Services Manager and select the Default Web Site. I then select the Exchange folder. Select properties. Directory security tab and the Anonymous Access and Authentication Control. I select edit and then change the access method. This works fine until I reboot the server. Then all access methods are back to the default. Please HELP!!! This is also the same for the other folders. Is there a template being applied or WHAT! I am at a total loss. Thanks for any help.
