Let $G=D_p$ be the dihedral group of order $2p$ , where $p$ is an odd prime. Let $k$ be an algebraically closed field of characteristic $p$ . We show that any action of $G$ on the ring $k[[y]]$ can be lifted to an action on $R[[y]]$ , where $R$ is some complete discrete valuation ring with residue field $k$ and fraction field of characteristic $0$
