Although the Windows Server service is self-tuning, it can be also beconfigured manually through Control Panel Service. Normally, the serverconfiguration parameters are auto-configured (calculated and set) each timeyou boot Windows. However, if you run NET CONFIG SERVER in conjunctionwith the /AUTODISCONNECT, /SERVCOMMENT OR /HIDDEN switches the currentvalues for the automatically tuned parameters are displayed and written tothe registry. Once these parameters are written to the registry, you cannottune the Server service using Control Panel Networks.

If you add or remove system memory, or change the server size settingminimize/balance/maximize), Windows does not automatically tune theServer service for your new configuration. For example, if you run NETCONFIG SRV /SRVCOMMENT, and then add more memory to the computer, Windows does not increase the calculated value of autotuned entries.

Typing NET CONFIG SERVER at the cmd prompt without additional parametersleaves auto tuning intact while displaying useful configuration informationabout the server.
The Server service supports information levels that let you set eachparameter individually. For example, the command NET CONFIG SRV /HIDDENuses information level 1016 to set just the hidden parameter. However,NET.EXE queries and sets information levels 102 (hidden, comment, users,and disc parameters) and 502. As a result, all parameters in theinformation level get permanently set in the Registry. SRVMGR.EXE and theControl Panel Server query and set only level 102 (not level 502) when youchange the server comment.

Administrators wishing to hide Windows computers from the browse list or changethe autodisconnect value should make those specific changes usingREGEDT32.EXE instead of the command line equivalents discussed above. Theserver comment can be edited using the description field of the ControlPanel Server applet or Server Manager.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
