We’re gonna solve the DHCP server authorization issue in this post. Error code looks like below:

“The authorization of DHCP Server failed with Error Code: 20070. The DHCP service couldn’t contact Active Directory.”

dhcp-post-config-20070 error

This is possibly due to user permissions on AD. Ensure you input Domain Administrator (DA) Credentials in the DHCP Commit dialog box, instead of proceeding with logged in account. There are chances that though you logged into DC using some user credentials, it doesn’t necessarily mean you are DA/EA. It could just be an account Admin locally, but not on Domain/forest. Check the DA user in ADUC and ensure you input those credentials to solve this.

Other things you should try if the credentials are DA is, ensure AD services are up and running. Check launching ADUC, Try Restarting DHCP Server services, Try re-installing DHCP from server manager. If you still encounter any issues, please message here, so we can further look into it to get it resolved.

Cheers!

[Solved] – [sqsrvres] Failed to start service with error 1062. Please try again

SQL cluster resources may be failing to start in the cluster with no specific error thrown when you are trying to start the SQL Service from the cluster window. If you Generate the cluster logs or in the Event viewer cluster logs you may see this annoying “[RES] SQL Server <SQL Server (DTA)>: [sqsrvres] Failed to start service with error 1062. Please try again”

 

This error doesn’t really give you real clue what’s wrong with the SQL service. You may have to go to Application/System Event logs to find the real cause. The following error will be displayed in the logs section “Unable to allocate enough memory to start ‘SQL OS Boot’. Reduce non-essential memory load or increase system memory.”

This means that there’s not enough memory available on the Cluster node to start the SQL services. You can either failover the SQL service/other concerned service to other participating node or increase the Memory of Cluster node if memory is being fully utilised.

Cluster Logs reads as below:

If the cluster nodes are VMs and you have Dynamic Memory configured on these VMs, then Live migrate the VM to a more capable VM Host to fix the Dynamic Memory not being allocated to the VMs by the cluster.
