How to reinstall NetBT in Windows XP SP3
Reinstal NetBT


Obtain and place a copy of "C:Windowssystem32driversnetbt.sys" in that path. If its missing and no local backup exists you can download the correct service pack the machine is running and extract the service pack and then from the i386 folder. It will be named netbt.sy_ so copy it and then rename it to netbt.sys.
I exported the Registry service for NetBT from another machine running Windows XP Service Pack 3 and imported into the machine to replace the missing NetBT service.
◦HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesNetBT

Reboot the machine.
Open Start, Run, then cmd to launch a command window and enter the following as a single command line.
◦Reset WinSock entries to Defaults: netsh winsock reset catalog
◦Reset TCP/IP Stack entries to Defaults: netsh int ip reset c:reset.log

After the first reboot after adding the NetBT Service Registry keys the DHCP service will most likely work but you're not done yet as no interfaces are associated with NetBT. So you'll be able to connect to websites but not access network shares and other odd behavior, Be sure to run the Netsh commands. You can test if they're working by the following.

Running "nbtstat -R" returned.
◦NetBT is not bound to any devices

If you do not have a windows XP Machine copy this to Notepad and save it as NetBT.reg... Then import that reg file....
