How can you enable remote connections using TSQL?

I know how to enable remote connections using the Surface Area Configuration tool.
Seems there would also be a way to configure it using a TSQL command/procedure call.
thanks,

You can use sp_configure to enable the features exposed by Surface Area Configuration tool. To see the options, run following first:
exec sp_configure 'show advanced options', 1;
reconfigure with override;
Please take a look at topic below in Books Online for more details.

For remote connections, you have to use SMO to do it. Doing it from TSQL directly is not possible since it requires manipulation of registry values and please don't use the undocumented XPs for registry manipulation.
