HELP with SP_configure

I am running the following command:

exec sp_configure 'allow updates', '0'

I get:

Server: Msg 15247, Level 16, State 1, Procedure sp_configure, Line 169
User does not have permission to perform this action.

What's causeing this?

Thanks!

Kenyou need to be associated (at least) with serveradmin role to be able to perform this operation. check with your sql server dba on that.
