Windows 7: How do i know why Static IP address dropped and getting into DHCP

15 Sep 2014   #11

Windows 7 Professional 32bit

Hi 2xg,

It is very random and it is not specific to one computer. So it is hard for me to check each computer in production. Would you be able to tell me any other possiblity so that i can run all test all in one time in production.

To consolidate all my details about scenario. we have 1 serve and 40 computer connected to server in workgroup.
Every time when rebuild image of each computer we will run script to setup ip address and other application which are required by orgnization. At that time when setting ip static address it drops static ip address and gets into DHCP. I observed that it creates "Local area connection 2" instead of "Local area connection"

Sounds to me like it is creating a second local area connection when it reboots which is set to DHCP and not assigned a Static IP like you want. Why it creates a second one I'm not sure, but it sounds like it is disabling or uninstalling the first connection and when it reboots it reinstalls it again, hence it has a 2 on the end of it.

I'm not an expert on this so as has already been said try disabling the DHCP client on the affected machine, and I would personally try and set up the router to give a static IP to that PC's Hardware MAC address.

Thanks for your reply Steve..!!
It was designed to set Static IP as per our organization and what ever you said is true. I too dont know the reason of uninstalling first Lan connection.
Disabling the DHCP client, need to do on all computer because it is random and when i re-image same computer it gets static IP. From my observation some times it couldn't able to set the static IP that's why it is going to DHCP.

From your DHCP Server or Router (whatever is assigning Auto IPs), please check the setting on how the IP Addresses are excluded from the distribution outside the DHCP Scope, make sure that you have 40 Static IPs excluded (including the Router's IP) - i.e., and your DHCP Scope perhaps should be something like -
