a box 2 2 2 is pretty small !! In anyways the simulation 
of
a box of water is pretty straighforward. If you get so 
much
troubles there is certainly a trivial problem that you
introduce. The cutoff of the vdw interactions at 0.8 nm
is one possibility. May be you get a standard file of
MD in gromacs and check the basic parameters for Temp, 
Pre,
cutoffs ... and it should work.
