Before installing Windows Server 2019 Time，Have noticed that the Server Core environment is selected by default，I feel that Microsoft wants to push the operating environment of this instruction mode。And after completing the Windows Server installation，When opening the Server Manager，Then it will suggest that we try to use “Windows Admin Center” IT，So if you want to say it, then try Windows Server 2019 Server Core install Windows Admin Center。

Wrote an article last week "Application specific permission settings cannot include CLSID – SQL」，At that time, I saw it in the system event record on SQL Server，The permissions in question are in the role of SQLSERVERAGENT，There is no problem with the permissions of the server itself (SYSTEM 及 Administrator)。I saw the same message on the AD server today，This time, the server itself has insufficient permissions，Therefore, multiple steps are required to retrieve the permissions from regedit。

We have several servers in the "system event" there will be many Schannel error messages，Click to show “The following serious warnings have been generated: 40。The internal error status is 1205。” Or “Received TLS from remote client application 1.2 Connection requirements，None of the encryption package servers supported by the client application。SSL connection request failed。” Wait for error message。The reason for this message is that this server provides encrypted services，But the user did not make the connection request in an encrypted way，I, for one，The two servers where this message appears are the Mail Server and the electronic sign-off server，Both use SSL certificates。

Previously because the AD domain was 2003 Hierarchical relationship，So on Windows Server 2012 When you want to join the domain in a later version，You have to go to the "function" side first and put SMB 1.0 Client installed，To successfully join the domain。Recently my colleague upgraded the AD domain to 2008 R2，So I want to shut down the SMB v1 of these servers，To improve security。And when you want to remove，Unable to uncheck，Therefore, the removal method is commanded instead.。

A very special situation happened today，On Windows Server 2012 Adjust the "Security" of a printer in R2，Masaru “Everyone” After changing the "Print" permission from "Allow" to "Deny"，It disappeared from the "printer" page，Go to "Device Manager"，Also disappear，But the print screen in Excel is still visible，From “\\localhost” I can still see it (Originally opened sharing printing)。Tried to restart Print Spool service and restart，The results are still the same，So I had to try the command mode instead，Change permissions back。
