SQL MA schema refresh error

SQL MA failed to retrieve schema with error 0x80231100. For me sollution was simple - add port to SQL server (replacement of old server and tests with a new server). So from someSQL.some.domain to someSQL.some.domain,4773 - is enough to refresh schema.

dns record timestamp in Active Directory partition

how to force AD to replicate timestamps? I can't use Scavanging - too many different objects - huge risk of loss of data, I can't enforce every device to reregister.
Idea to enable scavanging on zone is useless - as long as I will not run it on server level this setting is useless.
The only way is to remove stale records tracked by timestamp distributted accross thirty domain controllers (in four domains). We can recognize records from workstations (laptops, pc and virtual desktops) by ip addresses, but why it can be automated?

stupid office.com as a blank page

I don't know how and why but for sometime I had blank page on edge set to office.com. Without a reason it was set without option to change in settings. At first I thought to download admx package because in local policy I couldn't find settings for Edge. Today I come to my sense and in registry I removed NewTabPageLocation pointing to office.com on computer settings policies Software/Microsoft/Policies...

Still no solution - only forced gpupdate helps.

huge netbios traffic

according to this link from spiceworks maybe some old printer causing huge network traffic on NetBIOS - 137 tcp/udp:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers\Client Side Rendering Print Provider\Servers*oldservername*

I've got such scenario - near 20k workstations with some missing printers causing huge network - netbios - traffic. Maybe there are resposible for it?

exhausted connections? exhausted sockets?

Windows 2019, Windows 2022 by default has got port available from 49152 to 65535 - available 16384 ports. On another server I've got the same issue - no connection to domain controller or to different server, connections reamains intact, I can connect to server remotely - by C$ or by some ports, on server I can't establish new rdp connection with message that there are no available domain controllers, gpupdate is not working, zabbix monitoring is not working, but... after change of available ports by expanding range to 32768-65535 magically everything start works.
