When you are logging onto a Windows machine you will sometimes notice that it is taking a long time… usually you just blame GPOs and move on… If you want to get a hint on what´s taking so long you can set a GPO setting which turns on detailed information during logon
There are two different settings depending on which OS you are running (pre 2008R2/2012 or later)
You will find the setting in gpedit under Computer Configuration – Administrative Templates – System
The setting is called:
Pre 2012: Verbose vs normal status messages
Post 2012: Display highly detailed messages
