Before you edit the registry, make sure you understand how to restore it if

topic in Regedt32.exe.
SYMPTOMS
When the Small Business Server (SBS) computer connects to the Internet Service Provider (ISP) through a dial-up connection, the following event is generated in event log:
Event ID: 4319
Source: NetBT
A duplicate name has been detected on the TCP network. The IP address of the node that sent the message is in the data. Use nbtstat -n in a command window to see which name is in the Conflict state.
After the duplicate name is detected, all NetBT operations on the server fail. These operations include network browsing and the Manage Server Console.
CAUSE
This problem is caused by the SBS server registering the computer name or domain name with the WINS server at the ISP. The name will attempt to register with the WINS server until the WINS server responds with the duplicate name error. The SBS server will not function using NetBT.
RESOLUTION
This problem should be corrected by removing the WINS server entries on the RAS phonebook entry that is used to dial the ISP.
Follow these steps to remove these settings:
- Go to Dial-Up Networking.
- Select the Phonebook entry used to connect to the ISP.
- Click More, and then edit the entry and modem properties.
- On the Server tab, select TCP/IP Settings.
- Change the primary and secondary WINS addresses to all zeros.
MORE INFORMATION
Some ISPs are automatically creating these entries for SBS customers and entering the WINS addresses. These should be in the registry key listed below, and not on the phonebook entry.
Most ISPs do not use WINS. The ISPs that support the online signup servers for SBS do use WINS to allow the SBS customers to have dynamic IP addresses for their dial-up connections. WINS is used by SBSETRN to register a secret name with the ISP for mail retrieval. The dial-up connection should not register the local computer name. SBSETRN does not need these addresses configured on the phonebook entry. It uses the WINS servers configured in the following registry location:
