is it possible to play with friends over tcp/ip on windows 7 64 bit? I have friends that live too far away for a local LAN party that may enjoy this game. Was wondering what he word up on multiplayer capability is.
Thanks!no one has any input?

Yes it's possible, I've played it 1v1 on 2 WIn7 x64 computers. I had to completely remove all the ipv6 stuff, though I did that ages ago on my machine since it causes problems with old games.

If they're not local as you say, then hamachi will do the rest for you.

Remove all ipv6, got it. That's what I did and I still cannot connect. I'm thinking it's the method I used to remove IPv6. I followed this guide: http://www.home-network-help.com/disable-ipv6.html

Can you please clarify what you did so my hair can grow back?

All those steps seem correct, you did do a restart?

Whats the output of ipconfig in a command prompt. It should only list physical connections and no tunnel services or anything. (Others might show up like Hamachi/VirtualBox etc)

If theres a tunneling device listed, check your device manager, right click on 'Computer' on the start menu and select 'Manage' click 'Device Manager' on the left.

Under network adapters disable 'Teredo Tunneling Pseudo-Interface' if you have one, or something similar. I have no idea about any long term effects of doing that, but I have no need of ipv6 ATM and havn't had any issues.

Let me know how it goes.

Thank you for replying. I rebooted after the regedit. I even checked my ipconfig output. I looked just like your example in the Windows 7 Multiplayer topic (http://www.gog.com/en/forum/total_anihilation/windows_7_multiplayer)

I didn't have a tunnel device listed.

I did even more troubleshooting. Here is a link to the forum where I posted my mess on: http://www.tauniverse.com/forum/showthread.php?t=41582

Take a look at that thread and see if I missed anything. This will also give you a better idea of what I am dealing with. I was even tempted to completely re-format and start from there.
Thanks again for replying. I look forward to your next reply.
EDIT: To be clear, the "fix" that I listed in the forum isn't really a Fix. I would like to figure out how I can run this game on Win 7 and actually join a multiplayer game.

The only other thing I can think of ATM is if TA is binding itself to the wrong interface, I've seen games do this sometimes when they only expect a computer to have one IP it binds to the first it finds.

Try disabling all but the connection with the other computer on it.

What about firewalls on the machines, are they disabled?

I'll see if I can think of anything else.

Edit: Just noticed you said the firewalls were disabled in the other thread...

Would it be binding to another interface even though I can see the hosted game? I have VMWare interfaces and a Hamachi interface but my LAN is first in the priority list.
I see traffic going between them but something isn't right because that connection never really get's established.
I'm really curious what the differences between your PC and my PC could be that breaks multiplayer and apparently many other player's multiplayer.

I think the XP VM is really the only option/workaround here. I'm willing to test your ideas if you have more.

Can't think of anything else right now.. My friend is on Win7Ultimate with his desktop, and Im on a Win7HomePre laptop.. both 64bit, both with 4gig ram.

You haven't mentioned anything about anti-virus software, have you checked that?

Wow... you really know how to do things the hard way. You're in for a world of pain trying to connect TA manually thanks to its use of DirectPlay for networking.

Just use GameRanger, and the rest won't be necessary.

I completely uninstalled my AV software to double check it wasn't an issue.
It's really weird that you can connect and I cannot. I'm going to do a fresh install of Win 7 X64 on a box I have laying around and see if it will work.

EDIT: A fresh install of Win 7 X64 is not the answer. Multiplayer does not work on a fresh copy of Windows 7 x64. I updated this copy of Win 7 with all Microsoft updates.

I have no other suggestions, I wish I could help more but I haven't had any problems with older games since disabling ipv6.. even SystemShock 2 works fantastically in MP.

Thank you for your time!

I seem to be in exactly the same situation - no matter what I do, I can't get my Win 7 machine to play nice with this game. I am trying to play a network game between XP and Win 7, but they won't talk to each other. This is despite the machines being able to share files, ping each other, etc.

At best I can host a game on the Win 7 machine which is visible on the XP machine. However, when I try to join, it simply freezes until I quit out of the hosted game menu on the other machine.

Has anyone got any other bright ideas about how to get this running? I have seen references to running it under a WinXP virtual PC in Windows 7, does that actually work?

Incidentally I can play Quake III networked on these same machines without a hitch.

I can confirm that the problem is due to the No-CD part of the GOG version. it works fine on windows 7 (even 64bit) when at least 1 player has an old version from the CD installed.

Then can we get some kind of fix? This is highly annoying. It lists win 7 64bit supported. Either change the page or change the exe.
