Windows 7 won't recognize XP PC in network [Solved/Closed]

Barbara - Last answer on Jul 10, 2010 6:57am BST
Hello,
I had a Compaq computer running Windows XP - used a Linksys WRT54G, Version 2 to network with my laptop, also running XP - everything worked fine. 2 weeks ago I purchased a new HP P6230Y loaded with Windows 7. When I set up the computer I attached the router to the new computer. I can't get the new PC to recognize the old XP PC and can't even go online with the XP. Do I need to somehow uninstall the Linksys info from the old PC? If so, how do I do that? Any help you can give would be appreciated!

Did you set up Homegroup for networking in Windows 7?
Homegroup only works with Windows 7 computers and will not talk to your XP computer.
If so, you will need to change the networking system to one that XP can use.

On your Windows 7 computer, click the Start button at the bottom left of the screen, then go to the Control Panel and choose Network and Sharing Center. Click the link under "view your active networks" (if you've set up a Homegroup,the link should say "home network").
In the next window choose "Work network" that will switch you from a homegroup to a workgroup so your two computers can talk to each other. Before you can network the computers, you must assign the same workgroup name to both of them and SHARE folders in Explorer.

The XP computer's internet problem is not related the above. If your broadband modem is connected to the router and the router is connected to each computer your should not have any problems. If you are using a wireless connection you may have changed the ID or keyword when you installed the Win 7 computer.

Good Luck

I was able to bypass the issue of my Windows 7 pro machine not seeing my 3 xp machines. I 'shared' the folders on the xp machines, then added the sharesas network drives on the win 7 machine. The mapping network drive worked when the path of the \\other machines was used. My primary concern was to share files and this worked perfectly.

I had my win 7 wireless laptop seeing and sharing nicely with my 3 xp machines on my home network from November 2009 'til around June 16,2010. (Throughout this period all machines were protected by McAffee suite.) At which point win 7 quit working with the other machines, no see even though had drives mapped and printers shared. Tried everthing including removing McAffee firwall. Nsda! Finally restored win 7 back to June 16, 2010 restore point and Voila! Things worked again -- for a couple days until MS sent 4 critical updates. Tried everthing again. Finally back to the June 16, restore point and Voila! again win 7 played nicely with others on the lan. Disabled McAfee firewall downloaded and installed the 4 MS crit updates. System worked for a day or 2 so made a manual restore point. Day later Win 7 quit playing again. Restored to the manual restore point of about July 5 -- This time didn't work. Will try the June 16 restore point one more time. If it doesn't hold to *$&^%^# with it, I'll share files with a thumb drive 'til MS and/or McAffee get their act together.

DOH! i found the solution to my problem after hours of searching on forums and I felt like an idiot after discovering it. When I first installed Win7 I "tuned" it up to make it faster per some tips i found on another website. In msconfig i disabled several services, two of which were IP Helper and TCP/IP Netbios helper. I went back and reinstated those services and rebooted and VIOLA! I had XP networking. This was also on top of all the other settings I found too (work network, same homegroup, no 128 bit encryption). Hope that helps someone.

Thank you for the answer about changing the Win 7 Network settings to "Work" rather than "Home" group.

This worked perfectly. And was easy to change & test.

I had similar issue trying to get existng network talking to new Win 7 install & have been looking at lots of forums to find that answer.

I think lots of people elsewhere are making it harder than they need to.

Figured it should be easier than lots of people are making it.

Thanks again. Saved lots of wasted time.

I am experiencing the same difficulties as others. My network consists of a Laptop running XP and two Desktops, one running XP and the other running Win 7. Prior to installing Win 7 on one of the Desktops my network worked as one would expect.......NOW......I'm here looking for solutions.

I have ensured that
1) all three machines are connecting to the same network
2) the Win7 machine is using a work network

The result:
1) both machines running XP see each other and the shares; neither see the Win 7 machine
2) the Win 7 machine does not see either of the XP machines

I don't know if this will add anything to the solution but I'm unable to get the Peer Networking Grouping service to run on the Win 7 machine. This service has two dependencies; Peer Networking Identity Manager service and Peer Name Resolution Protocol service. I'm able to start the Peer Networking Identity Manager service but am not able to get the Peer Name Resolution Protocol service to Start.

Does this have any bearing on the problem with which we are all struggling?

I had this issue, the solution is easy (you may have found it already)

On the windows 7 machine, go to the network and sharing center. Click on the "Advanced sharing settings".

Almost towards the bottom, there should be a "File Sharing Connections" section, which is probably defaulted to the 128-bit encryption. Change it to the 40 or 56 bit encryption and your XP machine should show up.

Mark, thank you! This was the missing link!

To repeat this (hopefully so the search engines find it) for sharing between Windows 7 and Windows XP you have to set your Windows 7 computer to the lower encryption setting before it will see the Windows XP computers on your network.

Thanks so much for your speedy reply! The strange thing is that my XP laptop is connecting to the internet fine and is recognized in the new Windows 7 PC. The problem remains with the XP desktop PC that the router was originally hooked up to. I double-checked everything you suggested - still no Windows recognition of the XP desktop or wireless internet connection of the XP desktop. When you mention the router being connected to each computer, I'm puzzled. It is cable-connected to the new Windows 7 PC and the XP laptop is picking up the wireless signal. The XP desktop is not. How do I connect it to the XP desktop - is there a setting on the desktop I need to change since the router was originally connected to this machine? I keep getting the message on the local area connection icon that a cable is unplugged.

Make sure your ethernet cable is plugged in from the router to the desktop. I'm not sure if this the fix but I was having the same problem and the ethernet cable was loose on the router side.

chranging the work group names to match, ex. mshome, then making windows7 a work network instead of home network will make it work

WayneW, you are so right!!! I have about 20+ years computer IT service experience, finally trying to set up my first Windows 7 laptop and running into the exact same problems. After connecting my Windows 7 laptop to the network/internet which took me half a Saturday it still can't see other XP computers in my network. Very frustrating to say the least... If there wouldn't be so many programs I'm using for SEO that are not running on Mac I would have switched a long time ago.....

PS: Sorry that I can't contribute to the solution, it's a great forum.... but it was good to rant :o)

I had the same problem and tried everything and the solution I finally found att Microsoft as follow:

If you're using Windows Firewall, you can skip this section, because Windows Firewall automatically opens the correct ports for file and printer sharing when you turn on network discovery. If you're using another firewall, you must open these ports yourself so that your computer can find other computers and devices that have files or printers that you want to share.

To find other computers running Windows Vista, open these ports:

*UDP 3702

*TCP 5357

*TCP 5358

To find other computers running earlier versions of Windows, and to use file and printer sharing on any version of Windows, open these ports:

*UDP 137

*UDP 138

*TCP 139

To find network devices, open these ports:

*UDP 1900

*TCP 2869

FOR ALL OF THE ABOVE PEOPLE where it didn't work even though all suggestions were followed, here's why:

Your routers needs to be connected DIRECTLY to your main (desktop) computer, not through another device. I had mine going through a VOIP adapter. I removed this, and how it works.

My problem is the other way round! We have 3 computers in the house, a new one with Windows 7 (64 bit), a notebook with Vista & a notebook with XP (home prem). The PC with 7 finds the other 2 computers on the network, the computer with Vista finds the other 2 computers on the network, BUT the computer with XP only finds the computer with Vista on the network!! Why can't it find the PC with 7?? Can anyone help?
I've already tried the fix which entails making it a workgroup & not a homegroup, but that didn't make any difference!
Phil.

Hi all. I had the same problem and did everything suggested to no avail. I could get to the Windows XP Pro SP3 computer with my Windows 7 Pro laptop, but got the error message when trying to open the shared folder. Some of these guys are reporting the issue correctly and I believe they did everything right. My tip, which did solve the problem was to add a registry entry that will increase the IRPStackSize to 15. Turns out for me the issue had nothing to do with networking. You can look here to help you solve your issue and read about the solution:

Normally desktops do not have the hardware for a wireless connection. Do you have an add on card or a USB wireless connection on the XP desktop?

Hi, I have similar problems, and have tried some of the previous suggested approaches - but with no luck.
I'm using win-7 pro 32-bit on one machine and win-xp sp3 on another. I have no problems connecting from win-xp to win-7, and I can also see the win-xp machine in win 7's network. But when I try to connect it just says that I might not have permissions use the network resource. I have shared folders on the XP pc and set permissions to Everyone.
I'm using both pc's to connect to my workplace network, so the workgroup is not standard, however it’s the same on both machines.

Any suggestions?

Martin
