I am having a problem at the moment where by I am unable to start the Listserv primary server. I am running a Windows NT 4.0. Originally I thought the problem was the fact that I had run out for license points, but after adding another 5 points I was still unable to start the service. I am now getting an error message that one of my lists is running with over 5000 subscribers, and that the High Performance version of Listserv would be recommended. Would it be possible that this is the reason why the service is unable to start.
