Why doesn't gpmc.msc work?

Question

Active Directory

There is a domain controller under windows2012 r2. After some time, it was necessary to rename the domain. Renamed with rendom . It seems that everything went well and without complications. Well, when I try to enter "Group Policy Management" a window falls out with the following content "Communication with the specified domain controller cannot be established. This affects the following domains in the console. Domain: OldDomainName". I can't get past this window.
