This article describes the following error that occurs during the NAC application server installation. "Error saving changes to COM+ Application ENDFORCE AuthGateway Server." This article also provides a workaround.

What to do

If the error "Error saving changes to COM+ Application ENDFORCE AuthGateway Server" occurs during the NAC application server installation, the default Access Control List permissions on the %windir%\registration directory may be experiencing problems after you install the Microsoft Security Bulletin MS05-051. For more information see, http://support.microsoft.com/kb/909444. The NAC application server requires Windows Server 2003. If you are installing the NAC application server on Windows Server 2003 and it is not running as a domain controller, use the following commands to set the correct directory permissions:

echo y| cacls %windir%\registration /G everyone:R system:F administrators:F
echo y| cacls %windir%\registration\*.clb /G everyone:R system:F administrators:F
