  We present an alternative interpretation for the putative symbiotic star DT
Serpentis, and its proposed planetary nebula (PN), recently announced by Munari
et al. Our analysis is based on their data combined with additional archival
data trawled from Virtual Observatory databases. We show that the star known as
DT Ser is not a symbiotic star, and is merely superposed on the newly
discovered but unrelated background PN. There is no evidence for any periodic
variability for DT Ser as expected for a symbiotic star. We further establish
that there is no physical association between DT Ser and the PN, which has a
considerably higher extinction, befitting the larger distance we estimate. The
significantly different radial velocities of the star and nebula also likely
preclude any association. Finally, we show that the mid-infrared source
detected by the IRAS and WISE surveys is actually coincident with the PN so
there is no evidence for DT Ser being a dusty post-AGB star.
