After I upgraded a few NAC Appliances from 5.X to 6.1.X or from 6.1.X to latest 6.1.182 I had sometimes the problem that NAC lost its DNS Server information in the /etc/resolvresolv.conf.
After dnetconfig (without changing something) all worked fine again.
Does anybody know a reason for that? It doen't happen on every appliance.
Best Regards
Michael
