Microsoft have released a patch to fix a serious vulnerability within
Windows NT 4.0 and Terminal Server. Even though Microsoft should not be
releasing any security patches for Windows NT 4.0 and Terminal Servers, they
consider this serious enough to highlight it. The bulletin can be found here :

Microsoft consider this a critical vulnerability and I would advise
they you patch any NT4.0 or NT Terminal Servers that you
support.
