I made a console for admins to use instead of the entier SMS adminisrator. When they open the .msc file on their PC running NT4, they get the message "Snap-in failed to initialize". If they log on at another PC they can open it. I have been checking Technet, and network properties in NT4.0 with no resolution yet. We are only using TCP/IP protocol. The snap-in is version 1.1, and we have at least verion 4.01 SP2 of Internet Explorer. Anyone have an idea what to look for next?<br>Thanks.
