Hi Habib,
You can try to add new Subnet if you have multiple sites if you are getting this error message. This error is caused by your server not seeing the active directory. You can go to your Active Directory, under Subnet > Right click then choose new Subnet. You just need to assign a relevant site to the Subnet. You can then go to your services console and restart the exchange services or restart the server once you are done.
You can also check the Default Domain controllers Policy option to check if the server have permissions on the Manage and Auditing and Security on User Rights Assignment.
