Granting stored procedure execute permissions from ASP.NET?

Bit of an emergency!
I do not have direct access to our SQL Server but I have full FTP access to the web server and have the db Username/passwords.
I need to grant execute permissions on a stored procedure, can I do this from an asp/ASP.NET page?
The DB guys take 24 hours to run a script against the database!
Any help would be greatfully recieved.

You can use a SqlCommand object, and set the command text to something like this:
Grant Execute Onsp_name To ASPNET
Then use .ExecuteNonQuery()
