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

19 Jan 2011   #41

Windows 7 Ultimate x64

Another idea, from mikefapp, "go to the Networking Properties of the connection from Control Panel\All Control Panel Items\Network and Sharing Center and turn off AGN Filter Interface (64-bit)" seems to be beyond my capabilities, since there is no such option on my machine; at least none that I can find, and certainly not at that location. The relatively useless Help does not even find any entries for "AGN".

If you can see your XP machien from Windows 7 and no access it,
check your share settings to make sure you still sharing something..

hope that helps.

Windows 7 Ultimate x64

I think the rest of the problem must on the XP machine, which claims the W7 machine doesn't exist. Also, the XP machine cannot seem to hang onto its workgroup name; I set it to WORKGROUP, and next time I look, it has reverted to MSHOME. Anyway, I have spent far too much of my valuable time on this idiotic problem; I'm calling the Geek Squad.

IPSEC services show as Started, Automatic. I haven't messed with any services.

Windows XP

I have two Win 7 64bit machines, one with Win 7 Pro and one with Win 7 Home Premium. The Home Premium machine can see the XP machine with no problem, accesses all the files. The Pro machine can't seem to see the XP machine in the "Network" area of Windows Explorer but can ping it and will see it if I map it as a network drive. I have gone through every setting I can think of and every suggestion on this thread except deleting and reinstalling the Windows Firewall. Both Win7 machines appear to be set up identically (but have different hardware, one is an HTPC and the other is my desk workstation). I just installed SP1 but still no joy. I did a clean install of Win 7 on the desk workstation about a week ago to clean out all the crud that had accumulated over the past 18 months or so. Before that, I was able to access the XP machine with no problem. So much for improving things.

xp pc is host to internet connection sharing

I am a newbie, not technical, know just enough to be dangerous.

Small work group. we had 3 xp pro sp3 pcs (towers, no wireless) connected via wired LAN. We use Internet Connection Sharing. The host PC has a 3g usb modem and software from cellular provider to access Internet (we live in a rural community, cable is not available, and forget FIOS). one of the 3 xp pcs died, and was replaced with a windows7 laptop.

the windows7 laptop can ping the ip address of the ICS host XP PC, the client XP PC and the network printer.

I've printed and read microsoft's instructions on internet connection sharing, and run windows7 troubleshooting and diagnostics multiple times. I believe everything is set up correctly. But the two xp pcs do not show on the networkdiagram, and the windows7 pc cannot get to the internet.

Possibly a simple firewall issue, but now i'm not sure after reading this post.

I have done NOTHING to the host XP PC nor to the client XP PC (other than restart the host PC, thinking that might be necessary after I got the LAN configured on the windows7 laptop).

What seems to work best is to change the Advanced Sharing Settings in Network & Sharing Center to "Enable file sharing for devices that use 40- or 56-bit enryption."

The other commonality seems to be that users who disable Services in Win7 can lose networking functionality. Win7 already has all Services not needed at Startup set to Manual on fast triggers. Tweaking Win7 beyond normal System settings will almost always come back to bite you.

W7 Professional

Just in case anyone else is frustrated. Found this today.

Control Panel -> Network and Internet -> Network Connection -> Network Adapter Properties -> TCP/IPv4 Properties -> General -> Advanced -> WINS - NeyBIOS setting -> Default.

Quote: "Use NetBIOS setting from DHCP server. If static IP address is used or the DHCP server does not provide NetBIOS setting, enable NetBIOS over TCP/IP."

My XP machine was on static IP address. Once set to DHCP, W7 sees it immediately even if LLTD is not running. Alternatively do what the note above says: Check "Enable NetBIOS over TCP/IP". Make sure you use same workgroup name on both machines.

Hope it saves someone's time.

Windows 7 Professional x64

I had my network running just fine. Windows 7 PC and an XP Laptop. I hadn't used the laptop for 6 months or so.

I could ping its name and internal IP address from the Win7 machine. But no access to the XPs share folders or see it on the network map on my Win7 PC when I just tried.

To resolve this, from the XP, I did the following:

Control Panel > Right click on the adapter ("Local Area Connection") > Properties > "General" tab > "File and Printer Sharing for Microsoft Networks" was unticked.

I have no idea how that got unticked, but that resolved it for me.
