A WINS server can typically service:
A conservative recommendation is that you plan to install one WINS server and a backup server for every 10,000 computers on the network, based on these numbers and the possibility for large-scale power outages that would cause many computers to re-start simultaneously.
Two factors enhance WINS server performance. WINS server performance can be increased almost 25 percent on a computer with two processors. WINS server name replication response time can be measurably improved by using a dedicated disk.
After you establish WINS servers on the intranet, you can adjust the time between a WINS client name registration and name renewal. This is referred to as the Renewal Interval. Setting this interval to reduce the numbers of registrations can help tune server response time. (The Renewal Interval is specified when configuring the WINS server.)
