Windows 7: Win 7 / XP on Separate HDD... No LAN connectivity

Win 7 / XP on Separate HDD... No LAN connectivity

Here's the situation:

Computer --> Modem --> Wonderful Internet

I originally had Windows XP Home (x86) on one HDD. I installed Windows 7 (x64) onto a separate HDD so that they wouldn't share the same MBR. So, in order to switch between them, I have to go into my BIOS and manually switch which HDD the system will boot to first.

My XP HDD seems to have absolutely no problem connecting to the Internet. I never have a problem.

However, when I switch to run the Windows 7 HDD, I seem to be having a problem with my DHCP server. When i run ipconfig /all from the command line, it's showing an address of 169.254.xxx.xxx - which would be an APIPA address.

IP Address: 169.254.xxx.xxx
Subnet: 255.255.xxx.xxx
Default Gateway:

I can't even run the /renew command.
I can ping the IP, so I know that my NIC is working properly.
The drivers on my NIC are up to date.

If you need anymore info, please feel free to ask.

Does anyone have a clue as to what I might be able to do to resolve this situation? I would really appreciate some input on this one.

First, you should set up a proper dual boot. Boot into Win 7 and use bcdedit to add the XP home as a boot choice and save. You may have to first assign a drive letter to your XP partition from within 7 if you haven't done so already.

Now when you boot up, you will be presented a choice for which OS you want, provided you added the XP correctly. This is if you leave your bios boot to the 7 drive.

If after doing this, you boot to the XP drive, it will only load XP with no choices.

Now as far as your connection is concerned in Win 7. Disable IPv6 if you do not plan on using the Homegroup feature and do plan on sharing with the classic Windows' method. If you do disable IPv6, also disable the IP Helper service.

Set a manual ip for the nic.

IP = same as router config page, only changing the last part to any number between 1-255 that isn't being used by any devices.

Subnet mask = 255.255.255.0

Default gateway = router's config page ip address. Usually 192.168.0.1 or 192.168.1.1.

DNS Server = same as gateway

Scan your system with Malwarebytes to ensure it is clear of any funk. Also make sure the mdnsresponder.exe is not in task manager and the Bonjour service is not installed on your machine. You do not want Bonjour lol. Check in services and in program files.

You could either temporarily or permanently disable the DNS Client service.

Open you hosts file and make sure nothing weird is going on there.

C:\windows\system32\drivers\etc\hosts, <That's for x86. Not sure about x64.

Thank you for the reply.

Well, since I don't have a router, I'm not entirely sure what I would need to put as my IP address or the default gateway. Would I need to contact my ISP? I have scanned both my drives with Malwarebyte's and my current AV (NOD32). They both come up clean, so I'm sure it's not a malware issue.

If I remember correctly, the way you're telling me to set the OS's up is by putting them on the same MBR. I don't want that should one of them fail. Now, if that's my only option, well then I guess I have no choice.

I have disabled IPv6. Should I try renewing the ipconfig by 'running as administrator'? I've been doing some research, and I've noticed that in order to run things like that, you do have to run it as an admin. Windows won't set the main user as an admin.

Again, thanks for the help.

You're welcome.

No, having the dual boot will not harm the other OS should one of the disks fail. If 7 disk fails, you can boot to XP as always previously by changing bios first boot. If XP disk fails, choosing XP at the startup screen will fail. 7 will not. You could then choose to figure out how to fix your XP or remove it from the boot menu using EasyBCD, should that ever happen.

Basically means that a dual boot menu will not "tie" the OSes together where they're codependent.

To attempt to fix your network problem:

Boot into XP. From command prompt, do

ipconfig, then hit enter. Write down the info there and use it to create a static ip address under IPv4 for Win 7. Make the preferred dns the same as default gateway.

Running as admin or using an elevated command prompt is always a good idea when trying to tweak or adjust settings.

Hey torrent,

So I did what you said and set my static IP to what my XP settings were... still nothing. I even tried to set the preferred DNS the same as what it was in XP. I ran as both the system admin and under my user name.

I did notice that my DHCP services were turned off. Is there a way in 7 to turn them back on? Or is that overridden when you set up a static IP?

Thanks again. I guess if this doesn't work, I'll just get rid of my XP HDD. Time to move on anyways. My RTM version should be here within a week or so.

In start menu search box, type services.msc, hit enter. Go to DHCP client and make sure it is set to automatic. Also, start it up if it's stopped.

This setting is completely independent from setting a static (permanent) or dynamic (changing) ip.

So, I ran services.msc and this is what it said:
Both my DNS client and DHCP Client are running, but according to the ipconfig command, DHCP isn't... Well, atleast is says that DHCP is not enabled.

It sounds to me like you are having the same problem I am. There's alot of people having this issue. I hope this can be resolved.

I'm not completely sure, but I think DHCP enabled saying no means that your router (or since you don't have one, ISP or modem) does not have DHCP enabled. On my router, I specifically disable the DHCP server and I have that command saying no too.

Perhaps this is a driver issue. A driver found elsewhere like on your motherboard manufacturer's site or even from a different manufacturer that uses the same exact network device as yours, may work.

You can start with trying this if you'd like:

Considering the page has a flashing "compatible with Windows 7" advertisement on it, it really should be the fix I think. Good luck.

Well... my MB just died, so I guess I'll have to figure it out later. Thanks agaiun for all the help. I just got the EVGA 790i FTW MB... so I'll work on 7 later.
