Hi
Assuming you have a MS Windows machine.
Look for a file called hosts.sam (a sample hosts file). Open it with notepad.
Let's assume the pc with the s/w on is TCP/IP is 192.168.0.11 and the PC you are on is 192.168.0.12, save the hosts file (without a suffix, ie no .sam) from notepad.
The file should read:
192.168.0.11 localhost
which tells Windows to direct queries for localhost to the pc with the address 192.168.0.11, I think. This will also allow cookies to work properly when generated by locahost (as they are with phpmyadmin).
