Primary DHCP-Server Stuck in Purgatory

UCS: 5.0-3 errata699

For the sin of playing “Inspecto” and modifying an existing policy"… I have managed to mutilate my DHCP server and in doing so now my entire network is stuck. When I first detected “something wrong” I attempted to uninstall the dhcp-server, believing I could reinstall. Well that landed my machine in a halfway on and the other half “missing” state of being.
Errors from SystemCtl and Journalctl

dpkg: error processing package univention-dhcp (–configure):

installed univention-dhcp package post-installation script subprocess returned error exit status 1
Errors were encountered while processing: univention-dhcp
Cannot find service-record of _pkgdb._tcp.
No DB-Server-Name found.
E: Sub-process /usr/bin/dpkg returned an error code (1)

As I said, this is the Primary Server and DC. There are records in the UCR that give me hope there may be some way to restore functionality without going back to one.

Ideas appreciated in advance.
