Good Morning Jsmulko
When more than one UCS system enters a Windows AD domain, they try to communicate with one another. Therefore the UCS systems searches for the DNS SRV domaincontroller_master record and tries to connect with it.
Deleting an UCS does not remove this record, it has to be done manually. This entry _domaincontroller_master has to be deleted. After which the system should be reinstalled.
- In the screenshot below, the name of the Windows Host is WINAD, and the domain name is adwin.intranet.
- Right click the highlighted entry and select delete.
