The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine the value of the serialNumber attribute for each Exchange Server object in the directory. If the string value for the serialNumber attribute of an Exchange Server 2003 server object contains Service Pack 2, it indicates that the Exchange server is running a pre-release version of Exchange Server 2003 Service Pack 2.
The Exchange Server Analyzer also reads the following registry entry to determine whether the RestrictionMethod registry value is present:
The Exchange Server Analyzer displays a non-default configuration message if the following conditions are true:
- The Exchange Server 2003 Service Pack 2 is installed.
- The RestrictionMethod registry value present and
configured to have a value of 2.
This configuration indicates that the transport components on this Exchange server will not expand membership of distribution groups when the server checks restrictions. This configuration provides the best performance for restriction checks.
If you believe the presence of and setting for the RestrictionMethod registry value is in error, you can use the following procedure to revert to the default configuration. However, because the presence of this key in combination with Exchange Server 2003 Service Pack 2 provides the best performance for checking restrictions, it is recommended that you leave the RestrictionMethod registry value at its current setting.
