Message 2

Your system has not been modified. To complete installation at another time, please run setup again.

CAUSE

This problem occurs when both of the following conditions are true:

The DefaultAccessPermissions binary value exists under the HKEY_LOCAL_MACHINE\Software\Microsoft\Ole registry key.
The user account that has logged on to the computer to install SQL Server 2000 Notification Services does not have default access permissions for Distributed Component Object Module (DCOM) applications.

Note By default, the DefaultAccessPermission binary value does not exist under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole registry key. The DefaultAccessPermission binary value is created when you run certain applications or when you configure the default access permissions of DCOM applications by using the Component Services tool.
