Explorer.exe/ThunkConnect32 problems

Getting an error message every time my Win NT4.0 workstation boots up to windows that says in the header “Explorer.exe – Entry Point Not Found” the body of the error says “The procedure entry point ThunkConnect32 could not be located in the dynamic link library Kernel32.dll”
I have tried using “regsvr32 /u thunkconnect32” to unregister the dll and then register it again, but i get the same error whether i try to register or unregister it “LoadLibrary(“ThunkConnect32″) failed. GetLastError returns 0x0000007e.”
I’m at a loss as to how to fix this error. Another thing to note is that everything works fine when you click “ok” on the initial error, but I’d reall like to resolve this anyway.
Thanks,
David Trocki
