On a system running Nt 4.0 workstation with service pack 6A installed I had to install a new network card. Of course it wanted the NT CD to get the required network files. Now i need to re install the service packs ??? If so how do I get service pack 4 to install ? It tells me 6A is already installed and won't install. I can reinstall 6A but it does not update the Network files that 4 does ???
