Cant find SQL Server

I have the following in my web.config

<appSettings>
<add key="strConn" value="server=10.100.1.2;uid=sa;pwd=;database=MyDB/>
</appSettings
and I am getting the following error message --

"SQL Server cannot be found or access denied"

if I replace the server IP address with server name, it works fine.

Am I missing something here? Help!

Thanks
