I’m introducing DHCP into my two-controller AD environment and ran into the following error:
Troubleshooting Steps:
1. Account used to install DHCP was in Enterprise Admins. Also added to Domain Admins group
2. Removed DHCP role from second controller, rebooted
3. Removed DHCP role from first controller, rebooted
4. Ran gpupdate /force on second controller, to ensure security group membership applied
5. Ran gpupdate /force on first controller, to ensure security group membership applied
6. Used ASDI Edit > Configuration > Services > NetService to delete both the DHCP objects
7. Forced replication
8. Re-added DHCP Role
After trying to commit, received the following error… again:
9. Enabled WinRM in GPO
10. Removed DHCP role from first controller
11. Deleted DHCP objects in ASDI Edit again
12. Forced replication
13. Re-added DHCP role
14. Rebooted
15. Success!!
What was the problem?
WinRM policy was preventing GUI to complete installation. The policy has since been restored back to how it was before, blocking WinRM once more.
