It is really important that the 2 NMR computers were built the same way so we could swap the racks without glitch. So far we, the HDice group, could never successfully have computer center to build any computer (for experimental or office use) without a lot of connection constrains and biannual password changing. It would be really hard keep track the login password of a spare rack if it's not on the network for a while. It took many months (and a few meetings with IT and their chain of command) to re-config the IBC computer connecting to the BlueJeans conferencing, after moving back to HDice Lab from Hall-B. </div><br><div>Could you please help us to rebuild the Rack 1 computer just like the the one on Rack 2, with or without the DSG login?
