By default, the following Windows 2000 services begin automatically on startup:
IIS Admin
World Wide Web Publishing
Simple Mail Transport Protocol (SMTP)
Collaboration Server requires only the World Wide Web Publishing and IIS Admin services. If you do not need IIS to provide SMTP service, disable the SMTP service or set the service to Manual on startup.
On the Windows Desktop, right click on My Computer and select Manage from the menu.
In the Microsoft Management Console window titled Computer Management, expand Services and Applications and click on Services.
In the right pane, right click on the Simple Mail Transfer Protocol (SMTP) service and select Properties.
In the Simple Mail Transport Protocol (SMTP) Properties dialog box, click on the down arrow next to the Startup type field and select Disabled. Click OK.
In the Management Console, right click on Simple Mail Transfer Protocol (SMTP) and select Stop from the menu (it may already be stopped).
In the Management Console, verify that the IIS Admin and World Wide Web Publishing services have started.
If both services are started, close the Management Console.
If one or both services are stopped, right click on the World Wide Web Publishing service and select Start from the menu. This starts both services. Close the Management Console.
