As mentioned above, all workstations are WinNT4 running on an NT4 domain (pdc, bdc).
The server the the workstations need to point to are license servers for the application.

DNS won't work because each license server is limited to 64 clients, that's the limit of the license file. Don't ask me why, but I have to work with it. This means that I have to manually allocate 64 machines to each License server via the the following hosts file entry:

mshost xxx.xxx.xxx.xxx

The kicker is that the name "mshost" is hard coded into the application and must be the same in each hosts file with a differenct IP address for each group of 64 workstations in order to manually point them to one of three license servers.

I haven't tried to code anything because I don't really have a clue where to start.

I hope this fills in the gaps, thanks.
