SYMPTOMS
Consider the following scenario:
- You have a computer that is running Microsoft Windows XP Service Pack 2 (SP2). Alternately, you have a computer that is running Windows XP Service Pack 1 (SP1)and that has hotfix 811513 installed.
- The computer has a primary Windows Internet Name Service (WINS) server assigned to it that resides in the local subnet and a secondary WINS server that is located in a hub site.
- The computer switches the primary and secondary WINS server settings after one of the following conditions occurs:
- Fifty percent of the Dynamic Host Configuration Protocol (DHCP) lease time has passed.
- You run the nbtstat -RR command to update the NetBIOS names.
- You run the ipconfig /renew command to reestablish TCP/IP connections.
In this scenario, the computer registers with the secondary WINS server and sends name update requests to the secondary WINS server, even though the primary WINS server is fully operational and the primary WINS server destination is reachable.
Additionally, when the computer switches the primary and secondary WINS server settings, the wide area network (WAN) traffic may increase because the secondary WINS server is located in a hub site.
