BPA Errors: DNS can't resolve GC, Kerberos, PDC Resource Record, etc.
Hello, I've been poking around this for hours now and could use another set of eyes. This server has been the PDC for quite some time but I discovered the last people that managed this place, didn't demote the old 2008R2 server (thankfully it still existed virtualized). So I was able to do a graceful demotion of that and removed it from the domain. I'm now trying to resolve some other errors in that come up in the BPA scan... All reference DNS and I just can't figure this out. I've been beating head against the wall trying to understand what's happening, This is MS Server Standard 2022 only 1 DC and DNS. (yeah I know, don't get me started, but it's a really small office)... Would love some suggestions. Thanks!
Server 2016 Std DNS BPA Errors
I have three DNS errors and a large number of warnings which I cannot resolve. There is also a problem with Windows Time which cannot resolve the time server and defaults to the CMOS clock. There is only one ethernet adaptor: IPConfig/all gives: Windows IP Configuration Host Name . . . . . . . . . . . . : XXX-Server Primary Dns Suffix . . . . . . . : XXX.local Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : XXX.local Ethernet adapter Ethernet: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Intel(R) I210 Gigabit Network Connection Physical Address. . . . . . . . . : AC-1F-6B-6A-2F-F5 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::f8db:3ccb:4fb6:a153%12(Preferred) IPv4 Address. . . . . . . . . . . : 10.0.0.100(Preferred) Subnet Mask . . . . . . . . . . . : 255.0.0.0 Default Gateway . . . . . . . . . : 10.0.0.1 DHCPv6 IAID . . . . . . . . . . . : 61611883 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-22-E0-CA-14-AC-1F-6B-6A-2F-F5 DNS Servers . . . . . . . . . . . : 10.0.0.100 127.0.0.1 NetBIOS over Tcpip. . . . . . . . : Enabled Tunnel adapter isatap.{7E07F518-866F-449E-8032-3F6AAF177C0F}: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Microsoft ISATAP Adapter Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes Tunnel adapter Teredo Tunneling Pseudo-Interface: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Teredo Tunneling Pseudo-Interface Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes DCDiag /test:dns gives: Directory Server Diagnosis Performing initial setup: Trying to find home server...
