Thx, I had time to recreate one more time, because it was bothering me that it didn't make sense that I only needed to Add Program to Firewall for one laptop. And, what I didn't notice, or what didn't register, was that when I undid Add a Program (java), when I started Minecraft, there was a prompt, asking if I wished to "Allow java thru firewall" or some such verbiage. So, I click Yes. I think I need to think more when I am using my laptop. Or maybe write things down. It gets confusing. Like, did I do this on that laptop or on this laptop? Be that as it may, Open to Lan is still working for us, and we are happy about that.

I concur.

Thank you Stirling. Here's what I forgot. My son's laptop is new. A couple days ago, I noticed that Windows Defender hadn't been activated. So, I activated it. I now believe that is what caused the problem in the first place. I just forgot I did it. So, I followed your instructions on his laptop. I also followed your instructions for my laptop.

Here's an interesting thing. My laptop is my "work" laptop. I.e., I really shouldn't be playing Minecraft on it - or changing the firewall settings. So, after I followed your instructions for my son's laptop and mine, I tested Open to Lan, and it worked!

Then, I went back to my laptop, and undid what I had done to it. I just wanted to see if it would work, since ostensibly, the only laptop that had a change since the last time it worked was my son's laptop. And, guess what? For some reason, I only needed to fix up the firewall problem on my son's laptop. I didn't need to do it on my laptop.

Someday when I have some time, I am going to look into this more. But for right now, I have some coal to mine!

Thanks again!

Forgot to mention, son has new Asus laptop with Windows 8 OS, 2 GB RAM, and I forgot what processor, video but they meet reqs, I checked. (Currently in use.)

My laptop is HP running Windows 7 Enterprise OS, 2 GB RAM

I don't run Hamachi.
Open to Lan working up until yesterday. (maybe 3 days, before, as we don't play every day).

On Laptop 1
I see the Lan World,the I select Join Server. Result: Connection Timed Out.
I try Direct Connect using the IPv4:##### shown for the LAN World. Result: Connection Timed Out.

On Laptop 2
I tried Open to LAN on my Laptop instead. (We usually Open to Lan on my son's laptop. I wanted to see what reverse result would be.)

When I Open to Lan, my son doesn't see it on his Laptop, and my World shows as 0.0.0:49387

I typed netstat -ab > %userprofile%\Documents\My Documents\netstat_results.txt at DOS prompt.
When I opened the NetStat_results.txt, I could not see anything related to java in the file. There was a lot in the file, scanned as best I could, then did ctrl f java.

Is there anyway I can get java to listen? : )

I can tell you that my laptop has 32 bit Windows OS, whereas my son's has 64 bit, based on what I saw under Control Panel/Performance Tools. Not sure that is issue, since it worked before.

We both have MC 1.4.7.
My son is finding a lot of coal and iron, and I am jealous because I can't get in. : ) MineCraft is the best, most unique game. Have really enjoyed playing.

I believe I have attached netstat_results.txt and netstat_results2.txt (Ran twice.)
Hope this helps.
Thank you for your time.
