In the runbox type ipconfig /all
Post the output.

i typed in ipconfig /all

and the black box opened and then closed. nothing else has happened.

 

[IronDuke]

Sorry. Try cmd /k ipconfig /all

 

[mattw]

"'ipconfig' is not recognised as an internal or external command. operable program or batch file"

thats what comes up, and i tried typing in ipconfig /all again in the box but same thing happened.

What OS are you using?

Hmmm you need to go to Control Panel -> Windows Setup. Check that you have TCP/IP installed.

 

[mattw]

Windows XP Home

i will give that a go.!

 

[mattw]

ive checked that, and yes it is installed.

What is the default gateway pointing to?

 

[mattw]

when i check out the properties of the connection it has all the ip address etc, but beside default gateway it is blank. it is sending data but not recieving.

Copy the address from the other computer. Go to the second tab to enter it.
