Configure the memory usage of the Server service

The Server Service enables the the computer to act as a file and printer sharing server. Windows server edition will by default configure it self to maximize memory usage for the Server service to act like network file server. If server role is only to act as file server for 10 users or less, then one should consider trimming down the memory usage of the server service.

To change the configuration of the server service:

WinNT4 - Go to Control Panel -> Network -> Services, and choose “Properties” for “Server”.
Win2k/Win2k3:
1. Open Control Panel and double click Network and Dial-up Connections
2. Right-click the “Local Area Connection” and select properties
3. Select “File and Printer Sharing for Microsoft Networks” and press properties

The different configurations to choose between:

Minimize Memory Used
Balance
Maximize Throughput for File Sharing (Will also enable LargeSystemCache)
Maximize Throughput for Network Applications

The change of configuration will be reflected in this registry key:

[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \lanmanserver \parameters]
size = 1 (1 = Minimize, 2 = Balance, 3 = Maximize)
