you don't really need to phone anyone.
On the gateway machine (the one that's directly connected to the internet) open up Command Prompt, and type
ipconfig /all
This will tell you how things are setup on that box. You'll see something like:
From this section note down IP Address (1). There will be another lot of similar information, this time with DNS Servers and Default Gateway. Note down DNS servers (2).Etherned adapter Local Are Connection:
Connection-specific DNS Suffix:
Description: 3Com..
Physical Address: 00-01-02-03-04-05
IP Address: 192.168.0.1
On the 2nd, 3rd, 4th... computer, right click on 'My Network Places', choose 'Properties'. Rightclick on 'Local Area Connection' choose 'Properties'. Find Internet Protocol (TCP/IP) in list of items that this connection uses, click on it, then click on 'Properties' button.
Tlick 'Use the following IP address'. IP Address, put the same as your gateway; but add one to the last number. (in my example this would make it 192.168.0.2). under Default Gateway, put IP Address of the first computer (ie 192.168.0.1).
Then tick 'Use the following DNS server addresses' and put in DNS servers you noted down in (2).
Click ok on all dialog boxes, reboot the 2nd computer. Move onto 3rd, and repeat the process (add two to the last number of gateway IP number -- each IP number must be unique).
Away you go.
Without this, some misty WinXP bugs cause Anarchy Launcher to time out / cant find dimension on 2nd, 3rd... etc computer, if gateway computer logs in first. However, problem doesn't exist if those 'other' computers login first.
G'luck,
