Hi,

I am trying to network 3 computers together for LAN parties at my house (mostly RTS games like Command & Conquer, Age of Empires, etc.). I have been having some issues. Right now I am using a simple switch with each computer connected to by a cat6 ethernet cable. I tried numerous tests by creating network games on age of empires to see if they could recognize each other.

For ease of explanation, we'll call them computer A, computer B, and computer C. Here is what I determined by creating a network game on each computer:


Computer A
Will not recognize computer B
Will recognize computer C

Computer B
Will recognize computer A
Will not recognize computer C

Computer C
Will recognize computer A
Will not recognize computer B


So, computer B is not recognizable, but computer C is not recognizable only by computer B, and computer A is fully recognizable. This is very strange to me. I have tried this with firewalls off and that didn't matter.

Also, the IP addresses on each computer (for TCP/IP v4) are 192.168.1.102, 192.168.1.103, and 192.168.1.104 The computers all have different names and belong to the same workgroup. I have administrator privileges on all of them. All computers are running windows 7 ultimate x86. Computer A is a desktop with up-to-date hardware, Computer B is a 1 year old laptop, and computer C is a ~6 year old desktop.

Any help would be appreciated...thanks

I just go to dos command window and type ping 192.168.1.xxx Right?

If the following is what you are looking for, then I'll go ahead and do it for all connections. Here's what I got from computer A:

C:\USER\RYANP~1>ping 192.169.1.103

When I do the same thing on computer A for IP 192.168.1.104 I get the same thing.

However, I tried on computer B and things got weird. This is computer B pinging computer A.

C:\USER\RYAN>ping 192.168.1.102

Pinging 192.168.1.102 with 32 bytes of data:
Request timed out.

Ping statistics for 192.168.1.102:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

and again on computer B, pinging computer C

C:\USERS\RYAN>ping 192.168.1.104

Yes that's not a typo. I typed in 192.168.1.104, and it said reply from 192.168.1.103. I'm not quite sure what that means.
