I downloaded minecraft_server.jar from here, and made run.bat which content is

java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui.

It runs well, I can connect with typing my IP, but my friend (Windows Vista - 32bit) couldn't connect to my server, even though he can connect to my Apache web server. (not the connection problem)

We had this problem months ago, and somebody told us the 32bit side (my friend) should open the server, and it worked.

However, my friends said to me that his computer is cr*p, so he can't run minecraft server well and asked me to find the way running minecraft server...

How to fix this problem - 32bit computer can't connect to 64bit minecraft server?

    Have you tried using 32 bit Java? I've done this (64bit server PC with 32 bit connecting people). – The Communist Duck May 17 '11 at 8:18
  • how did you configure the network settings for minecraft? is there a firewall? – user8949 May 17 '11 at 9:56
  • @bckbck : I didn't check... I'll do @The Communist Duck's method and check network settings if that method doesn't work.. – JiminP May 17 '11 at 10:31
  • whose method worked? so i/him can write our answers if it is correct, and you can mark the answer as correct – user8949 May 17 '11 at 11:19
  • @bckbck : Communist Duck's method. I downloaded 32 bit version and it worked. – JiminP May 17 '11 at 11:49

Download 32-bit Java and use that for the server.
