Can't see XP Machine in Windows 7

Good to Know :) Thanks.

let's hope the RTM address's this. The fix however is to type in the Computer name of the XP machine in the address bar of a local directory in Windows 7 and up pop the shared directories. This works if of course you can ping both the IP address or the Computer Name of the XP machine. I tried all the recommendations in this forum with no success. Hope this works for others.

Hi just wanted to share that I had a similar problem. Workgroup where Win 7 laptop could not see or access in any way Win XP Pro and Win98SE machines. Solution: Installed Link Layer Topology Discovery from microsoft.com on Win XP Pro machines allowing them to be visible in network map. Then in the Network adapter properties I unchecked Trend Micro NDIS 6.0 Filter Driver and that allowed access and visibility of all Win XP Pro and Win98SE machines.

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.

I've got the same e!@#%@#^% problem!!! Here's my config: 1. Wireless Router hooked to Internet (via ethernet cable to cable modem). 2. Windows 7 Desktop hooked to wireless router via ethernet cable. 3. XP Laptop connects to wireless router via wireless connection. Both can independantly access internet no problem. But of course, the Desktop and Laptopu can't see each other, nor share squat. The XP Laptop can ping the Win 7 Desktop and receives a reply. However, the Win7 Desktop cannot ping the XP Laptop (timeout after no reply). I've disabled all firewalls, anti virus software, and anti-malware software. P1's getting frustrated#$%@#$%

Ended up finding my problem.

In the XP wireless network connection Properties window, The "Client for Microsoft Networks" was unchecked. DOOH!

On my machine it was not a firewall issue. On the Windows 7 computer I had to 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).

I had the same problem, Win 7 64 would not see XP box. I went to "Network and Sharing Center" > "Advanced Sharing Settings" scrolled down to "File Sharing Connections" and changed the setting from 128 Bit encryption to "Enable File Sharing for devices that use 40 or 56 Bit Encryption". Then I could see my XP machine.

Disclaimer, this worked for me but I have not completely understood all the forgoing in this thread. With 4 pages of replies, I did not read all completely, and did not see this "possible solution" mentioned.

Put XP 32bit on a box instead of XP64bit because of a recording issue,
was unable to network them,
could ping thier names, thier ips, etc.

Until I tried JoeMaxx solution I was about to give up..
setting the encryption lower and they popped right up on both machines.

I wonder how many more hours I'll have to waste before I stumble on some way these two machines can access each other? It's taken me a lot of hours already, just to get to this suggestion: install LLTD on the XP machine.

So I downloaded the LLTD installer and ran it on my XP SP3. Result: one error message saying "Setup has detected that the Service Pack version of this system is newer than the update you are applying. There is no need to install this update." So much for that fix.

Next I tried the suggestion to drop the encryption to a lower level. Aha! Now W7 can see there is an XP machine on the network, and knows its name, but still cannot access it. Windows Network Diagnostics merely says "Windows can't find a computer or device named [XPNAME]". Knows its name, but can't "find" it? So, how did W7 discover its name?? This makes no sense at all to me.
