why the machine does not get its IP address automatically from DHCP server instead it takes IP from the range 169.*.*.* and the user can not surf on internet neither he can access rest machines in the perticular domain? please give a permanant solution for this problem.

Hello, the 169.*.*.* IP address is what we call APIPA IP address. It is assigned is no DHCP server gave the computer an IP address or no static IP address is configured. Is the DHCP server in the same network of the computer? If yes, are you able to ping the server is you fix a static IP address? If it is in another network then you have to configure a DHCP relay agent. Please check event logs on the DHCP server for more information. For the client computer, please make sure that DHCP client service is running. This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hi, Some added to Mr X’s opinion: If you want to judge the problem is caused by client or sever, you may repro the issue and capture network package on client and DHCP sever. You may capture network package by following steps: 1) Download NetMon3.4 from the following website and install it on the computer http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=983b941d-06cb-4658-b7f6-3088333d062f 2) Launch NetMon3.4. 3) In the Microsoft Network Monitor 3.4 window, click Create a new capture tab … 4) In the new tab, select all the Network Adapters in the Select Networks window. 5) Then, switch to Network Monitor, press F5 to start NetMon. 6) Run CMD as administrator,ues “ipconfig -release” and “ipconfig -renew” to repro this issue. 7) Go back to the NetMon window and press F7 to stop the NetMon. 8) Press Ctrl+S to save the Netmon file named test. 9) Upload the file via SkyDrive ,and post a link here. Focus on the DHCP package: 1. If the client does send a DHCP discover package, you should check the DHCP client service. 2. If the client send a DHCP discover but the sever doesn’t receive the package, please check the network between the client and the sever. Since the client broadcasts messages on the physical subnet to discover available DHCP servers. I just wonder whether the client and the sever in the same subnet? 3. If the DHCP sever receive the package but didn’t sent the DHCP offer package, you should check the setting for DHCP sever. For example, if there is a MAC binding is set for this client, and the IP address is occupied.
