system error 85 "local device name in use" when using net use to map printer to lpt1/lpt2/lpt3


  • When I execute "net use lpt2 \\machine\printer"  I receive

    System error 85

    The local device name is already in use

    "Net use" shows that nothing is currently mapped to lpt2.

    New connections will be remembered.
    Status       Local     Remote                    Network

    OK           V:        \\xxxxx          Microsoft Windows Network
    OK           W:        \\xxxxx          Microsoft Windows Network
    The command completed successfully

    Device manager only shows a physical lpt1 which I have disabled.

    Local machine is win7 sp1 - remote machine is winxp sp3 Has not solved the issue.

    I get this error on lp1 and lpt2 and lpt3 as a standard network user with administrative privilages on both the local machine and the remote machine.
