JSI Tip 4700. Is your Windows XP Server service still self-tuning?

Just like in Windows NT and Windows 2000, if you ever run the net config server command, with the /autodisconnect, or /srvcomment, or /hidden switches, the then current values of the auto-tuned parameters are written to the registry, destroying the ability of the Server service to auto-tune itself.

To restore the Windows XP LAN Manager Server parameters to their auto-tuning state:

1. Use the Registry Editor to navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceslanmanserverparameters.

2. Delete all the Value Names (in the right-hand pane) except:

      EnableSharedNetDrives       Lmannounce       NullSessionPipes       NullSessionShares       ServiceDll      Size

3. Shutdown and restart your computer.

The only safe way to set the values that the /autodisconnect, or /srvcomment, or /hidden switches set is to use the following tips:
