Globally we have around 8 AD servers, Last week all sudden one of our ABC Domain Controller got some drive issue where SYSVOL stored. Problem is after several hours all the scripts and gpo folders are missing in other 7 Domain Controller's, but ABC DC has all the folders also we noticed lot of DFS errors and blocks on the D drive errors on ABC domain controller. To fix the issue I shutdown the ABC DC and restored sysvol from backup.
I need help how can we prevent these type of issues where one specfic DC got some issue and impacts all other domain controllers, all gpo&scripts are missing in SYSVOL which cause major issue. All our 8 server global catalog servers.
