If you use Windows NT Workstation 4.0 in a non-networked environment, you can save memory and system resources by disabling the following services.
- Alerter. Sends alert messages to specified users when an event occurs.
- Computer Browser. Lets you view the shares of other computers on the LAN through the Network Neighborhood icon.
- DHCP client. Disabling this service won't prevent you from getting an IP address through DUN.
- Directory Replicator. Synchronizes the \%windir%\system32\replimport subfolders with the PDC.
- Messenger. Lets you send Net Send messages to other computers on the LAN.
- Net Logon. NT uses this service mainly in validation. If you don't use DUN to log on to your computer, you can disable Net Logon.
- Network Dynamic Data Exchange (DDE) DSDM. Maintains a database of all your computer's shared connections.
- Remote Access Autodial Manager. According to Microsoft, you should enable this service if you want to be able to autodial to your ISP. However, disabling this service on my computer didn't prevent me from using autodial.
- RAS. If you don't use your computer to accept dial-in connections, you can disable this service.
- Task Scheduler and Scheduler. As their names imply, these services are responsible for automatically running jobs, such as programs and batch files. By default, they don't contain any jobs. If you don't schedule jobs for automatic execution, you can turn these services off.
- TCP/IP NetBIOS Helper. This service helps IP-to-NetBIOS name resolution. If you're not networked, you can disable it.
- Telephony service. If you use your computer to dial out, set this service to automatic. Otherwise, you can safely disable it.
