Win 7 Pro loosing IP address
Posted on 2012-08-16
I am running a three site Windows server 03 domain hosting mostly Windows XP, with a growing number of Windows 7 Pro Workstations. I only have one Server 08 machine, and it is a member server.
We have had several Win 7 machines running successfully for a couple months now, but over the last two weeks or so, I have noticed that from time to time, a machine will "Loose it IP", and automatically revert to the alternative IP scope built into the OS options. Once it does this, the user can't connect to the internet, or even any of the local server based resources.
Best case: I reset the IP config and it finds the correct IP and reconnects.
Worst case: Today, about half of my users, mostly Win 7 but also windows XP users could not connect to the network at all and reverted the the Alternative IP, a local profile, and no network drives.
This last issue was resolved only after I reset the network switch, router, and most of the users workstations. I was able to fix it, but I am still not sure what happened.
The only thing that has changed is I changed our DHCP scope to include more IP addresses (same IP scope, just more addresses included as available). Other than this, and some random Windows updates on the Win 7 machines, I can see nothing different.
Thanks in advance for your assistance.
