Accessing VB Dot net exe acroos Win NT

i complied a exe in Vb not net Beta 2 version.
after i moved that exe to some other machine.
but when i tried to access that exe from a different machine..
i m not able to access Command() it's throwing some security exception..
same thing happens when i create a new instance of File System object..
i would b pleased if someone tells me how to overcome this
security exception..i wanna access this exe across neteorll.
reply back

In NT some programs wont run unless the user that is logged in has the right security privileges.

Does that computer have the beta 2 framework installed?
