At our large FITES events, we disable NetBIOS to prevent leechfests and bogging down the network. In some instances, this setting does not reset to the default enabled setting, which can cause some problems accessing shared resources on your home network when the LAN is over.
To reset your TCP/IP settings, click on Start, then Run, and enter the following text in the run box or copy/paste it:
netsh int ip reset c:\tcpipreset.log
Hit enter to execute this command. You should see a DOS window flash on your screen briefly and then go away. A log of the command's results can be found in c:\tcpipreset.log.
