Windows 7: Can't see XP Machine in Windows 7

26 Feb 2012   #51

Windows 7 Professional 64 bit

I am experiencing a similar problem, but not the same as all responders. I recently upgraded my desktop to Windows 7 Professional with a separate partition, so I can still use it in XP Professional. Now I can not see my Windows XP Laptop when I boot up in Windows 7, nor can my XP laptop see my desktop when it is in Windows 7 mode. A friend has a Windows 7 Home Premium laptop, and I have no problem networking my XP laptop or desktop in XP mode with that W7HP laptop, and vice-versa.

Another interesting fact is that my W7Pro desktop sees all my other wifi devices (TV, Blu-ray, receiver, printer, roku) but not the XP computer. Not only that, but my XP laptop sees everything I just mentioned Except the W7Pro desktop.

I checked and double checked all the settings mentioned previously, including firewall settings, but no success.

Is there a simple solution? What is going on here? Is Windows 7 Pro just too complex to work for the average person?

Have you run the Sharing Wizard in XP Control Panel or from the Network Connections page?

In WIn7 have you enabled Network Discovery and File and Printer SHaring in Advanced Options of the Network and Sharing Center?

Can you ping the other PC (PC name or IP address)? Try this from each PC.

Windows 7 Ultimate x64

Up untill a few weeks ago, (running an XP and Win7 network) I had no problems with networking. Even using a USB printer installed on XP machine for printing from Win7 machine.
I have tried and tried to get the networking function back. (makes you want to tear your hair out, doesn't it)

Tonight I was looking (for the fifth time) at the properties of "Local Network Connection" on the Win7 computer and finally noticed this;

Sunbelt software firewall NDIS IM filter

mixed in with my ver 4 and 6 tcp/ip, Client for Microsoft Networks, etc.

I disabled the NDIS IM filter, and had my network working fine.
I think this thing was installed when I installed Spybot S&D or AdAware.

I had uninstalled them after I used them, maybe the uninstalls left the NDIS IM filter.

Windows 7 Ultimate x64
!!!Problem Solved!!!

I have been having this exact same issue for about six months now with no solution but to use the FQDN of my XP machine.

This is useless when my routed dumps all leases upon restart and i have a few wireless devices attached to the router, one being my xp laptop with the printer im trying to access. Thus having to fix the FQDN share name every time i restart my router is an absolute pain, not to mention very slow due to the inherent lag of a fully qualified name.

So I spent a few hours researching the problem and have found the solution to mine.

1. Disable the IPv6 protocol on your 7 machine (if you don't need it, this speeds up LLTD responder requests)

2. Open the network interface properties on the XP computer that is connected to the network. (mine is wireless so i select the wireless adapter properties)

3. Click the Advanced Tab

4. In the Windows Firewall Box, Click the Settings button.

5. On the first page, make sure the firewall is On, then uncheck the "Don't allow exceptions" checkbox.

6. Click on the "Exceptions" Tab, make sure the "File and Printer Sharing" checkbox in the list is checked.

Then click ok on this window and the adapter properties window, restart the computer and once the machine has rebooted back into windows, it should work fine.

I hope this helps anyone else that has been hiving this problem for as long as I have
