MS-Logon problem after new Windows updates

Post by adamcios »

MS-Logon and MS-Logon II stop working on Windows 10 22h2 after new Windows updates

When I try to use MSLogonACL.exe and import file which i used in last years

File to import mslogon_AD_default.ini
mslogon_AD_default.ini
allow 0x00000003 .\adminek
allow 0x00000003 ..\VNCEdit
allow 0x00000001 ..\VNCView

I get such info:
"C:\Program Files\uvnc bvba\UltraVNC\MSLogonACL.exe" /i /o "C:\Program Files\uvnc bvba\UltraVNC\mslogon_AD_default.ini"
Detected computername = KOMP3
account: KOMP3\adminek, mask: 3, type: allow
Detected domain = XXXXX
XXXXX\VNCEdit: SID not valid.
Detected domain = XXXXX
XXXXX\VNCView: SID not valid.
RegSetValueEx passed
deleting ACE_DATA linked lists

I try to check MS-Logon and MS-Logon II and I get such info in logs:

Code: Select all

Password authentication accepted from 192.168.12.1 (Interactive) (ID:1)
MSLogon authentication refused from 192.168.12.1 using XXXXX\vncadmin account (not authenticated)
Password authentication accepted from 192.168.12.1 (Interactive) (ID:1)
MSLogon authentication refused from 192.168.12.1 using vncadmin@xxxxx.lan account (not authenticated)
I checked everything I could and the result is still the same. Any suggestions?
one more thing when I deinstall windows updates:
KB5028244
KB5028166
KB5028412
KB5027937
If KB5028244 is not installed, uninstall KB5028166
In some cases, if that doesn't work, you need to uninstall KB5028412, KB5027937
But this is not a solution.
