I've just been through this too. The trouble is probably common to anyone 
using Julia in a workplace with Windows and no administrator rights (so 
that network drive is always popping up). I wrote a julia.bat file:
set JULIA_PKGDIR=D:\Julia.0.3.2
set HOME=D:\Julia.0.3.2
D:\Julia-0.3.2\bin\julia.exe

which in my case points to D:\Julia0.3.2 where I have locally installed. 
Then use that julia.bat file to start it each time.
