Change display style in enumerate

Question

I want to change the style of each element inside enumerate. It should be:

Ad (1)
Ad (2)

I have tried to do it by:

\begin{enumerate}[Ad. (1)]
  \item 
  \item
\end{enumerate}

But a result is not what I expected. I would like to change it only locally inside specific enumerate block. And I don't want to use any extra package.

You need to change the definition of the label for the first level enumerate environment.

\documentclass{article}
\begin{document}
\begin{enumerate}
\renewcommand\labelenumi{Ad (\theenumi)}
\item a
\item b
\end{enumerate}
\end{document}

Note that the effect is temporary; it only applies to this instance of enumerate. Also, if you embed enumerates within each other then inner instances will use enumii, enumiii and enumiv in place of enumi.
