"No adapters bound to TCP/IP are enabled for DHCP"....whatever that means.
TCP/IP is a protocol for networking. It's to do with IP addresses and how things communicate.
IP addresses to computers are like phone numbers to houses. Each one needs a different number. They're broken down into 4 sections, and look like this: 198.162.0.1
Now what DHCP is, is a way for the network to automatically configure all the computers that are connected to it, so they all have unique IP addresses.
So, with that said, it appears your Network Interface Card (NIC for short) (or USB Dongle, or how ever you connect to the network) isn't configured to allow the DHCP to assign the computers address.
Now I've not really dealt with Win2000, but in XP it's controlled under Network Connections, in the Control Panel, and you right click the desired network and select properties. Then in the scroll down box you scroll to "TCP/IP" and click the Properties button...and the options are there to set it up for auto-config.
Like I said, I don't know too much about Win2000, but someone will do if you can wait.
In the mean time, try using another method, or a similar device to try and connect...I was t/s'ing at a friends house, and swapped the device over and it worked first time.
