To configure the registry key on the file server (Windows Server 2003)

1. From the command prompt, run regedt32 to open the Registry Editor.

2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters.

3. If it does not exist, create a DWORD "MaxMpxCt" and set the value to 800 hexadecimal. This specifies a value of 2,048 decimal.

4. If it does not exist, create a DWORD "MaxWorkItems" and set the value to 2000 hexadecimal. This specifies a value of 8,192 decimal, or 4x the MaxMptCt.

5. Reboot the machine.
