NoteHKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 1 - 125 requests | 50 |
Specifies a suggested limit on the number of outstanding client requests that can be maintained for each client on this server. Because the limit on outstanding requests is negotiated between the client and server and enforced by the client, this value might not be the actual maximum used.
Increasing this value might improve server performance, but it requires more receive buffers (work items) on the server.
Note
For Windows NT 4.0 Service Pack 3 and later, the valid values for this entry range from 1 to 65535 requests, with a default value of 50 requests. For Windows 2000, the maximum value for this entry is limited to 125 requests to assure that Windows 95 and Windows 98 clients can connect to the server.
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
Tip
If you are running Windows 2000 Terminal Server with many clients and are experiencing communication delays, you might improve server performance by increasing the value of this entry.
