www.BlackViper.com: Windows XP Service Pack 2 Services 411 - Secondary Logon

Secondary Logon

Default Description:

Enables starting processes under alternate credentials. If this service is stopped, this type of logon access will be unavailable. If this service is disabled, any services that explicitly depend on it will fail to start.

Additional Information:

I have never found a reason to keep this service running. I have always considered "Alternate Credentials" someone other than me. Not my idea of fun... Really, though, it allows a "limited user" account to start an application or process with higher privileges, such as the Administrator account or another user. You can also have a privileged user start an application or process with limited privileged account. If you right-click a file, the menu will display "Run As" option. If you disable this service, that function will no longer be available.
