Every version of Windows NT (and later derivations) has had separate server and desktop-targeted releases going back to "Windows NT 3.1" and "Windows NT 3.1 Advanced Server".
One could change an NT4 workstation install into a server install with one or two registry changes and a reboot.
There may have been a few binaries on the AS install media that were harder to come by, but in general the editions were licensing segments and not really different products.
Ahh. I wasn't sure about NT 3.1 as it's the only version of NT I've not had to manage. In fact quite possibly the only version of Windows I've never used even once.
