I have 3- 4.10 servers (one tree), 1- 3.12 and 1- 3.11 Novell server at one site. There are about 350 users whose workstations are dropping mapping and capture commands several times throughout the day. Workstations are either NT 4.0 or Win 3.1 with the latest Intranetware clients installed. We've checked for viruses (Mcafee) and only select groups (containers) are losing connectivity. These users are connecting to the 4.10 servers. No major changes have been made other than upgrading the virus s/w version and client s/w. Problems appear to be intermittent between containers and users. Servers are not maxed out with utilization nor are there are errors with the packets being received.
