Guys, this is a very specific issue that many of you aren't having. This is directly related to Windows 7 and Atheros network adapters. If you don't have both of those, you do not have this exact problem. Sorry, but you'll have to go elsewhere.
As for the solution, the only fix so far seems to be simply to buy a new network card. It's not the best solution, but I can confirm it works.
MikaV84, I like how the first comment there is "Have you port forwarded?" Hahaha. I'm so angry.
By the way, in your bug report, you blame it on the motherboard. That's not it. It's the Atheros network adapter they use. I have a different motherboard with the same network adapter.
I might try another PCI network card if I can find a cheap one that isn't an Atheros.
The thing that really confuses me about this is that this only happens with SMP. I've hosted other games including MC classic with no problems. Is it just that the SMP server sends so much outbound data?
This could also be an x84 vs x64 issue (32-bit and 64-bit drivers or OS causes issues with the server).
No, it happens on both 32-bit and 64-bit versions of 7. I know this because I'm on 32-bit as I mentioned earlier.
I have an ECS motherboard with the Atheros L1 onboard. I have Ubuntu also installed on this computer, and I just tried running the server from that, and it worked fine. Like I said earlier, I had no problems with my Vista computer on the same network. We can definitely narrow it down to Windows 7 and the Atheros L1 then. Now it's time to find a fix that doesn't involve buying a new network card. :| Any ideas?
And I've been saying it has nothing to do with the router. It's a bit counter-productive when you try to help by saying things that aren't even relevant to the problem. Tried running with or without administrative permission. No difference at all. :\

Yes, Froggeh. Look at the ****ing screenshot. I specifically pointed it out there! I have been setting up and maintaining home networks for nearly a decade. I know what I'm doing.
Anyway, I ran the server on my Vista 64-bit laptop, changed the port forwarding to that IP, and someone was able to connect. This proves beyond a shadow of a doubt that the problem is local to my desktop PC. No more ****ing IP related or port forwarding posts about this are required. Seriously. Please. This is not a port forwarding or IP related problem, for the millionth ****ing time. Stop. The problem is local to the machine running the server.
kert06, welcome to the party. Is that Windows 7 you're using? We all seem to be Win7 users...
EDIT: Changed the post title to more accurately reflect the problem.
Also, what ethernet controller do you guys have in the device manager? Mine's:
Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller
Ok, this is a major question I must ask ALL of you as it seemed to be a HUGE problem with my friend... Yes, you forwarded the ports, HOWEVER... Did you forward the ports through the CORRECT IP... If you have multiple computers connected (like mine) your IP for the specific computer you are on could be (example) 192.168.0.3 or 192.168.0.70 or anything in between and more. I will post a quick guide showing you how to check if someone says they do NOT know how to check.
Have you not even been reading the replies in this thread? I even posted a picture to show that my port forwarding was correct.
deadly4u, I just ran a speed test:
Download Speed: 14730 kbps (1841.3 KB/sec transfer rate)
Upload Speed: 491 kbps (61.4 KB/sec transfer rate)
Are you really so ignorant as to think that you have tried -every- last possible option and exausted -every- last resource at your disposal because you are so damn perfect. Thus leaving the ONLY plausible reason as to WHY your server doesnt work, despite the THOUSANDS OF PEOPLES WHO GOT THEIRS TO WORK, is due to a fault in minecraft itself?
You misunderstood what I was saying. I was asking what possible factors it could be and what factors we could rule out based on our previous experimentation. Notice the question marks. Instead of calling me ignorant, maybe you could try to answer my questions.

ALWAYS turn off DMZ, DMZ is crap for people who don't know what they're doing.
Can you connect to your own server VIA localhost, or your internal IP?
Are the people connecting able to connect to other servers?
Are IP addresses correct? Often people don't know what an internal/external IP address is.
Nat on your router open?
UPnP on?
Ports open for both UDP/TCP?
Lastly, have you and they tried to reinstall server/clients and make sure the same version is being used?
1) DMZ is off, and like MikaV84, I have tried to run the server by removing the router from the equation completely.
2) Yes, both.
3) Yes
4) Obviously the IP addresses are correct, considering we see the users connecting in the server log
5) Again, see #1
6) Yes, again see #1
7) Yes, see my previous posts in this thread.
8) Yes.
Again, both MikaV84 and I have the same problem when we completely circumvent the router and plug in directly to our modems. I think we can safely rule out anything router-related. For the love of god, port forwarding is not the problem.
What I'm asking for here is really ideas of where to start looking. I realize you guys don't know what the problem is because there's not enough information to diagnose it. Tell me what information you would need. I know my way around a computer, but I don't have a lot of familiarity with low-level networking and Java.
Like I said in the first post, I can see people connecting, and they kind of appear in game. That indicates to me that there is some kind of communication going on (and obviously that they have the right IP). The problem seems to be after logging in, so maybe during map downloading? Any idea where to start looking?

"but after a few minutes they get disconnected with an error message
Not to mention, you're identifying three discrete points where theres 'one' problem. Unable to connect? Getting errors during login? Kicked off a few minutes in? Which is it--all of them?
I guess I could have been more precise with my wording...
What I mean is the players themselves are able to connect, but they never make it in-game. The disconnect happens somewhere after I get the "[INFO] Username [ip] logged in with entity id X" message in my server console and before they are able to actually get in-game. I'm not sure what the user actually sees when connecting. I think all they ever see is "Logging in..." When I said they get disconnected after a few minutes, I meant after a few minutes of that screen, not of being in-game. They never actually get in. I can see their floating body if I'm connected locally.
I linked to those other posts to show that other people are having similar problems and to try to bring some attention to the issue. I linked to your post because it claims to be the definitive guide on the issue, when it's not.
Thanks for the backup MikaV84. Let me know if you figure anything out. It seems like firewalls, antivirus, routers, and UAC are pretty much out of the question. I'm also fairly confident it's not ISP or conflicting software related, considering we have no problems running other servers on the same port. What does that leave that could be at fault? Minecraft itself, Java, and the NIC?
The problem is that this can't be replicated, because nobody has any idea what causes it. Nobody even believes it exists outside of those who get it. Now instead of ****ing telling me to make sure my port is forwarded correctly (because it ****ing is), does anybody have any idea how to narrow this problem down? Sorry for getting impatient, but I'm tired of the ****ing canned responses. I know how to read all the 50 billion posts detailing how to forward ports and I have done it a million times, plus Minecraft Classic works fine on the same port (but not at the same time).
Useful answers now please...

1) I assumed it was pretty obvious that I am not trying to run anything else on the same port
2) Of course
I've tried different ports. Same deal.

UPDATE:
The problem here is that even with correct port forwarding/firewall settings users are able to connect to a server hosted on Windows 7 with an Atheros L1 network adapter, but they are stuck on the Logging in... screen before getting disconnected. The problem has been confirmed by several users in this thread. Multiple people have been able to get the server working on the exact same hardware using a different OS (Ubuntu and XP have both been tested this way). They can also host servers on different computers on the same local networks. Please do not post anything about port forwarding or firewalls. We have already found the cause of the problem and are now looking for a solution.
This problem is related to a combination of Windows 7 and Atheros network adapters. Any information on the subject would be appreciated!
Please go there if you're having this problem. Please note, if you are having a similar problem and are not on Windows 7 or with an Atheros network adapter, you probably don't have the same problem. We've narrowed it down with a good degree of certainty to this specific combination.
Old post:
There is a serious problem with the SMP server that seems to be completely ignored by the community even though people continuously ask for help about it. Their problems seem to just be passed off as "Oh, another noob who doesn't know how to forward ports..." While that may be the case some of the time, there is undoubtedly a more serious underlying problem. The simple fact is that even with correct port forwarding and disabled firewalls, a number of users are unable to host a server that anybody can connect to. Many of us who experience this problem are competent computer users.
So I'm starting this thread in hopes that people will realize that this is not a ****ing port forwarding problem and that there really is a problem here. Maybe someone can offer a helpful solution instead of "Run PFPortChecker...", "Make sure you're giving them the right IP", and all that ********.
The problem is that nobody can connect to our servers. We'll see a notification in the server window of someone trying to connect and their body appears hovering in the world, but after a few minutes they get disconnected with an error message. The message they receive varies, and the same person attempting to connect to the same server consecutively can get a different message. Last time I tried hosting, I saw overflow and genericReason. I'm 100% certain my port is forwarded correctly (classic server on same port works, PFPortChecker says it is, I'm not a retard, etc), and I have disabled Windows Firewall. I'm using a D-link WBR-2310 router and I'm running Windows 7 Ultimate 32-bit.
For my mining, I just designate a large area I'm going to mine and start digging it out, 2 layers of block at a time, building spiraling stairs around the side as I go. It ends up with a really awesome strip mining look and gives TONS of stone, which is what I build everything with.
Here are two examples. The larger one on the right goes all the way to the bottom.
I prefer to avoid exploring caves as much as possible, because it's really dangerous and easy to get lost in.
ZarroTsu's idea is a sound one though. It provides adequate lighting and looks pretty nice.
I think this argument goes deeper than just whether or not hacks are acceptable. It's a matter of personal philosophy when it comes to games. Many people get more enjoyment modifying a game to make it what they want it to be. Then there are those who prefer to play games the way they were intended to be played. I'm in this second group, and I see Minecraft's player physics as an important gameplay mechanic rather than a limitation to creativity.
