This article describes procedures for manually configuring the server service.
There may be times when it is necessary to configure the server service during a scripted, or unattended install.
To configure the Server service, follow these steps:
When you configure one of the four options for the Server service, the information is saved to the following two registry keys:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters\sizeYour choices for this registry key are 1,2 and 3.
1 = Minimize Memory Used
2 = Balance
3 = Maximize Throughput for File Sharing and Maximize Throughput for Network Applications
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache
Your choices for this registry key are 0 and 1.
1 = Maximize Throughput for File SharingSome programs, such as SQL and Exchange, set this value during an installation. For these programs, the optimal setting is 0.
0 = Maximize Throughput for Network Applications
0 = Indicates that the computer does not go outside its cache pool and use program memory to perform I/O functions.
1 = Indicates that the computer looks outside of its cache pool and uses program memory to perform I/O functions. This occurs if the cache is full.
The Windows NT 4.0 Resource Kit contains a tool called Regini.exe, which can be used to script changes to the registry. For information about this tool, please refer to the Regini.doc file or type regini /? at the command prompt.
