SYMPTOMS
When a DHCP-enabled WINS client performs a name registration with WINS, it gets a Time To Live (TTL) value. In certain conditions, after the first refresh cycle occurs (at TTL/2) or when a nbtstat -RR command is issued, clients may refresh the name cache very frequently.



CAUSE
After the first refresh cycle occurs or when the nbtstat -RR command is issued, the WINS client starts to refresh every 10 minutes. This causes the load on the WINS server to increase and causes the WINS server to enter &quot;burst&quot; mode and give lower TTL values to all the clients, even for new name registrations.
