WINS máy chủ Windows 2000 cũng tương thích với "downlevel" (NT), các máy chủ WINS, cho phép nó để cùng tồn tại một cách hòa bình trong lai Windows 2000/Windows NT mạng 4,0. Trong phần này, chúng tôi sẽ kiểm tra các loại trao đổi đã diễn ra giữa WINS client và máy chủ WINS, và nhìn vào các Agent Proxy WINS. | 270 Chapter 6 Troubleshooting Windows 2000 NetBIOS Name Resolution Problems Figure Configuring Advanced TCP IP Properties settings.

Troubleshooting Windows 2000 NetBIOS Name Resolution Problems Chapter 6 271 The Windows 2000 Windows Internet Name Service WINS The Windows 2000 WINS server is fully RFC-compliant and includes many extra features that optimize its use on Windows networks. The Windows 2000 WINS server is also interoperable with downlevel NT WINS servers which allows it to peacefully coexist in hybrid Windows 2000 Windows NT networks. In this section we ll examine the types of exchanges that take place between the WINS client and WINS server and look at the WINS Proxy Agent. NetBIOS Name Registration When a WINS client starts up it will register its NetBIOS name with a configured WINS server via a NetBIOS Name Registration Request. If the WINS client s name does not already exist in the WINS server s database the WINS server will send a Positive NetBIOS Name Registration Response to the WINS client. If the WINS client s name is already in the WINS database the WINS server returns a WACK wait for acknowledgement message to the WINS client. The WINS server then issues a challenge NetBIOS Node Adapter Status message to the IP address associated with that NetBIOS name in its database. If there is no response from the registered owner of the NetBIOS name the WINS server will return a Positive NetBIOS Name Registration Response to the WINS client and its name and IP address will be recorded in the WINS database. If the owner does respond to the challenge the WINS client that is attempting to register the name will receive a Negative NetBIOS Name Registration Response and will not be able to initialize its TCP IP stack. note_ If the computer that is registering its name and the IP address is the same as the one in the WINS
