also, to install the client, you need to do it from the winxp cd. I forgot the where in the menu it is but the client is on the winxp cd. Also, you can use the older terminal services client to connect to winxp but you won't get sound and you're limited to 256 color.
not important but ff you connect to a win2k terminal server using the winxp terminal services client, I think it sends sound to the local computer which the older version can't do. Also, the new client is better than the old one.
