Windows 7: No IP Address when rebooting

Windows 7 Enterprise Edition 32-bit
No IP Address when rebooting

I just did a fresh install of Windows 7 Enterprise on a new 1Tb HD. I also have a 500Gb HD with my old XP system on it, and I use the F12 boot menu to choose which system to boot up while I'm "building" up the Windows 7 system.

Whenever I reboot into Windows 7 after having run WinXP, I am unable to connect to the internet. The Windows 7 troubleshooting always fixes the problem by renewing the IP address.

If I reboot the system from being in Windows 7 back to Windows 7, no connectivity problem.

Is there some setting that I can tweak so this doesn't happen? Or should I just live with it until I'm fully up and running on the new Windows 7 system, which will probably be within a week or so.

Thanks for any help.

Try setting a static IP address for both XP and 7. For example, set XP to use, and 7 to have

Thanks for your speedy response to my query, Jonathan.

I was able to apply your suggestions and they appear to have resolved the problem.

I tried to do the same in my XP system, but I was unable to connect to the internet when I applied the same information to the adapter properties. When I switched back to DHCP, I was again able to connect.

Thanks again.

Great, thanks for reporting back.

One thing you can do is look in your router for the DHCP settings. I have mine set to assign IP addresses in the range 100-125.

If you tell XP to get an IP address automatically, but tell 7 to take an IP address outside that range (say 35), they will never conflict.
