Cannot connect to sql server using IP Address
===

I'm setup MSSQL Server for my company and I have got a problem, I use both MSSQL 2000 and MSSQL 2008. When I use Query Analyzer or SQL Server Management to connect to my server, I can't not use IP Adress to connect to my server.For example if I use ComputerName\InstanceName it will work, but if I use IpAddress\InstanceName it will not work and show an error message "Specified SQL Server not found".How can I fix this error.
