Nortel Networks NN46110-602 manual What can you try on the Wins server when it is not working?

Chapter 4 Troubleshooting 85

The renewal interval governs how often a client must reregister its name with the WINS server. It begins trying at one-half of the renewal interval. The extinction interval governs the length of time between when a client name is released and when it becomes extinct. These intervals are the most important to control when using dynamic addresses.

There is a trade-off in setting these intervals. If they are set too small, there is too much additional client registration network activity. If they are set too large, transient client entries do not time out soon enough. If you also have secondary WINS servers, make the renewal interval the same on the secondary servers as on the primary server.

For additional information on setting interval values for a WINS configuration, see the Microsoft Knowledge Base article Min. and Max. Interval Values for WINS Configuration available at www://support.microsoft.com/support. A WINS server that has a heavy CPU load or network load does not perform well. To help performance:

•Do not run other intensive tasks on the WINS server.

•In the WINS configuration, disable detailed logging.

•If you have primary and secondary WINS servers, assign them a balanced load.

For hosts that never change IP addresses, you can give static entries in the WINS database. For example, you can configure the address of the Primary Domain Controller as static. To do this, you also need a statically reserved DHCP address for the primary domain controller.

What can you try on the WINS server when it is not working?

You can request that the WINS server clean up its database by going into the Mappings menu and selecting Initiate Scavenging.

If the database becomes very large, you can compact it by using the jetpack.exe program in \winnt\system32. Consult the WINS Help before doing this because the server must be shut down.
