Your user profile is being probably reset on each AutoCAD launch (using some custom mechanism) or you have no read/write access to your profile.

System variable setting is also one of big issue,well u all have discussed well about it and I really appreciate with that.Thanks for sharing itDisaster Recovery Plan
