SYMPTOMS
When you use Windows Internet Naming Service (WINS) for name resolution, name resolution may not work as expected.



CAUSE
This problem may occur if both of the following conditions are true:
 * The primary WINS server is unavailable on the network.

-and-
 * Client records are not refreshed to the secondary WINS server.

If the primary WINS server is unavailable for a significant period of time, client records may expire and be removed from the WINS database. In this scenario, name resolution does not work correctly.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Microsoft Windows 2000 Service Pack 4.



MORE INFORMATION
Starting with Windows 2000 SP4 and later, if the primary WINS server is started, the secondary WINS server is stopped. If the client registers with a primary WINS server that has a Time-to-Live (TTL) value of less than two hours, at approximately half of the TTL value, the client tries to refresh with the secondary WINS Server, but it cannot because the secondary WINS server is stopped. The client continues to send refresh packets to the secondary WINS server until the time the TTL value expires. At that time, it refreshes with the primary WINS server.

Note This scenario was tested when the WINS server TTL value was set to both 40 minutes (the minimum setting) and to two hours.

When you run the nbtstat –rr command, the command releases with both WINS servers, but it refreshes with secondary WINS servers only, and then it repeats this behavior. If both the primary WINS server and the secondary WINS server are started, at about half of the TTL value, the client refreshes with the secondary WINS server, and it is registered with the secondary WINS server with a new TTL. value. The nbtstat –rr command releases with both WINS servers, and refreshes with the secondary WINS server only.
