Limited connectivity on some machines- DNS?
For some bizarre reason I have suddenly started receiving 'limited or no connectivity' issues on a number of machines in our ICT suite. We use software called 'AB Tutor' which is classroom management software and I have noticed that some of the machines aren't being picked up and other are displaying the wrong 'name' (e.g. IT001 is actually IT004) etc...
If I login and renew the ip- all is well again.
I have also noticed that all the ports on our switch are periodically flashing at the same time, all together intermittently. Could this be connected?
