Thank you everyone for your help.
How did I end up with a Korean version of W2K when I don't understand the language? Serves me right for buying anything from ebay!
I have been able to set English through Control Panel, but want to remove Korean entirely, which by the looks of it is not possible. I guess I will just have to bite the bullet and buy another copy of W2K, or put up with the control panels being in Korean.
Yes it is the same machine without the installation disc for W2k.
