That's actually incorrect that MS has not released a patch for 4.0. (Updated a couple PDCs with that a week ago ) If you go to the technet link they have a patch for both 4.0 and 4.0 Terminal Services. The regular 4.0 version SHOULD work on 3.51 as well. HOWEVER, it should be tested pretty good in a test lab first.

The patch is for Windows NT 4.0 Server and Windows NT 4.0 Terminal Services.

There is not an explicitly issued patch for Windows NT 4.0 Workstation or for Small Business Server, both of which are vulnerable but not listed as being so. They haven't been listed because they are no longer supported. One must be very careful about reading Microsoft's tech bulletins.

It is my understanding that the NT 4.0 Server patch will work on 4.0 Workstation. I have heard this from people whom I believe to be competant, but I haven't seen it with my own eyes. I haven't heard anything at all about SBS.
