Softether NTLM v1 auth. Event ID 4776.

Post by RiseTheFlag » Tue Nov 08, 2022 11:26 am

Can anyine help me plz?

I have SE 4.39 build 9772 installed on Server 2019. It works well as OpenVPN server with NT authentication, but i have numerous 4776 errors in Event Viewer:

The computer attempted to validate the credentials for an account.
Authentication Package: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0
Logon Account: ...
Source Workstation: SOME-SERVER-01
Error Code: 0xC0000064

Error code means "The username you typed does not exist. Bad username." in terms of Microsoft, but credentials are correct. Anyway, this error reveals when any user connects, but connection is successful at the end.

What can i do to prevent this error on server?

TY in advance.
