MSSQL 2000 running on my laptop

I am trying to set up everything to run on my laptop so that I can develop when away from desktop. I was trying to add cold fusion datasources throught the Cold Fusion Administrator and it was failing with some error which I have now forgotten.

The trick was to go the SQL Server Enterprise Manager, right click on the server, then select the Network configuration button at the bottom. Then I had to enable tcpip. This immediately fixed the datasource problem and everything is running good now. Don't know why that wasn't on by default. Maybe because it is an MSDE installation running locally.
