  A $D$-like meson resonance with mass around 2.9 GeV has been found in the
$DK\bar K$ system using two independent and different model calculations based
on: (1) QCD sum rules and (2) solution of Fadeev equations with input
interactions obtained from effective field theories built by considering both
chiral and heavy quark symmetries. The QCD sum rules have been used to study
the $D_{s^*0}(2317) \bar{K}$ and $D f_0(980)$ molecular currents. A resonance
of mass 2.926 GeV is found with the $D f_0(980)$ current. Although a state in
the $D_{s^*0}(2317) \bar{K}$ current is also obtained, with mass around 2.9
GeV, the coupling of this state is found to be two times weaker than the one
formed in $D f_0(980)$. On the other hand, few-body equations are solved for
the $D K \bar{K}$ system and its coupled channels with the input $t$-matrices
obtained by solving Bethe-Salpeter equations for the $D K$, $D\bar{K}$ and $K
\bar{K}$ subsystems. In this study a $D$-like meson with mass 2.890 GeV and
full width $\sim$ 55 MeV is found to get dynamically generated when $D K
\bar{K}$ gets reorganized as $D f_0(980)$. However, no clear signal appears for
the $D_{s^*0}(2317) \bar{K}$ configuration. The striking similarity between the
results obtained in the two different models indicates strongly towards the
existence of a $D f_0 (980)$ molecule with mass nearly 2.9 GeV.
