MSD Chemstation won't open - message "in use by another session"

Cannot get MSD Chemstation to open - get a message "Mass Spec is already in use by another session".  Version G1701EA E.02.02.1431 / WIN 10 operating system.  System was shut down temporarily and on startup,  the software does not open.  It is an Agilent 5975MS with a 6890N GC.  Tried rebooting the controller on the MS itself, but that did not work.  Also looked at binding order, but possibly did not do that correctly.  Both MS and GC can be pinged successfully from the PC.  Does anyone know what might be wrong?  Thanks

  • a good question! ;-)


    if you now repeat the powershell command you will see that probably both NICs will now have a value of 25.

    I prefer to manually set the chemical NiCs to a value of (4-)5, because many IT guys do this with their house NiCs.


    NOTE: unfortunately these manual values can get lost:

    1. after a LAN card driver update, or
    2. after Win10 troubleshooting function: reset LAN card
