Things to check after dcpromo:
1) Check inbound and outbound AD replication:
To determine this, execute: REPADMIN /SHOWREPL /REPSTO
Make sure all last attempts are really recent, and at least within the tombstone lifetime of the AD forest
2) If the DC is a GC, check it has finished the build of the GC partitions and it is advertising itself:
To determine this, execute: Get-WinEvent -LogName “Directory Service” | ?{$_.Id -eq 1119} | FL
3) Check the SYSVOL has been initialized and finished initial replication
To determine this, execute: Get-WinEvent -LogName “DFS Replication” | ?{$_.Id -eq 4604} | FL
4) In addition, check the NETLOGON and SYSVOL shares are in place:
To determine this, execute: NET SHARE
5) Check Event Logs:
The following event logs will help determine the health of the DC. Check the events with warnings or errors and resolve anything that needs to be resolved:
Event Logs:
Directory Service
DFS Replication
File Replication Service
DNS Server
Application
System
6) Run DCDIAG:
To do this, execute: DCDIAG /C /D /V
