Bruce here again, day 14 on my journey!  Tonight I’m studying Group Managed Service Accounts.  If you remember in 2008 r2 Microsoft introduced Managed Service accounts.  These provided us with a Service account that would provide automatic password management for a single account on a single server.  Microsoft has now improved on this feature by allow us to manage a single service account that can be used on multiple servers.  Now we can have a single identify that spans all of our services running on a server farm.  Below are some resources to help you learn more about gMSA.
