Toolbox questions

Hello all-

     I have a question regarding the toolbox items and fasteners.  When inserting toolbox fasteners into an assy the bill of material descriptions are lost when the drawing is saved and then reopened on another computer after saving to the network.  We are NOT using a vault.  The tooboxes we are using are not configured heavily and standard fasteners are being used.  We only have about 6 SW users here in the office.  Are toolbox links broken when pack and going a drawing and assy and then saving to another location and then trying to open it from another computer? Please advise- I appreciate the time.
