Suddenly my IBM T61 Windows XP Pro sp3 laptop will no longer connect to my Belkin router, either wired or wireless. This began after I allowed a series of Windows Updates to occur. Using ipconfig and other signs it appears that the DHCP process no longer
occurs. Looking in the Device Manager Non-Plug-and-Play I could see that there was a yellow flag next to 'netBT' which is a dependency for a number of services like DHCP. Windows suggested I uninstall then reinstall the 'driver' netBT.sys. Well, it uninstalled
OK but now it is off the list and without it loaded I am cut off from the network (I have a second Vista Home laptop that I am using to prowl for tech ideas). I moved a copy of netBT.sys from the Service pack 3 i386 folder into system32\drivers to replace
the old one, just in case.
How to I get netBT to load and function again? I have spent many hours rebooting, enabling and disabling, and anything else that I could think of or find on Tech Boards.

SOLVED. Corrupted NetBT registry entry. HKLM\system\currentcontrolset\services\NetBT
After many hours of detective work I found the clue in the Events log through MSCONFIG. Error type 7001 means service failed to start because of a dependency (I knew that), but it went on to say "dir name or path syntax not correct". I went into the registry
and used exactly the same path syntax as specified in NetBIOS "system32\DRIVERS\netBT.sys" and DHCP service started.
