If you have no problems saving to your PC, there is no problem with
AutoCAD/LT. Try it.
Most likely you either don't have write access to the folder in question, or
you have exceeded your 'quota-limit' assigned to you by your network
administrator.
Turn on BAK file creation, turn on AutoSAVE, set ISAVEPERCENT to zero in LT,
and ask your network admin to open up all folders for AutoCAD usage, no
limits.
