The client licenses are not additive. That is, you have 5 NT licenses and 5 "upgrade" licenses giving you just 5 licenses. All this at first may sound confusing but you may need to put aside your goal of avoiding license costs if you want this to work properly.
But one wonders if you could have used a Linux server in this case.
i needed to buy a new server, in order to replace the one is failing (running winnt 4.0 spk6), so i got a new one and i also have a brand new never open Win NT 4.0 server with 5 CLIENT ACCESS LICS. AND a new ugrade Windows 2000 Server with 5 client access licenses both of them new never used before so they are still legal, what i did was install win nt 4.0 and then upgrade it with the windows 2000 server upgrade version since this is just 5 client Lics so the only problem i have is that i need more than 5 to be able to connect to this new server, i need to know what do i have to do to increase the client access to allow more than 5 users to access the server and a multiuser application on this server do i need to buy some kind of cd to install more clients ? , by the way this server is acting as a storage server, i have not setup the server as a file server using the wizard i just simple shared a folder where the multiuser aplication is located and mapped the workstation to that \\server\sharename and also added users on this server thr the Manage and under local users i added 5 users with password but since i know this is only for 5 clients i need to know what else do i need to buy to install more client access and be able to add more users thr the Manage and local users, i need 23 users capables to access this application on this server simultanously(sorry i don't know how to spell it), can you please give me suggestions of what else i need to buy and install to increase the lics, so 23 users can access the server and the application ?
ps: maybe this was not the right way to install the os windows 2000 server upgrade but it is working and i just need 23 users to access this server and the application resinding into the shared folder.
Excuse my ignorance
