Unifi Network Controller is written in JAVA，So before it was installed in Window 7，But it often happens that the program fails，Later, it will restart almost every day，So I was thinking about whether I could make it a service，And the official does provide practice，But when doing，Pay attention to some places。

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。
Recently check the "event log" of each server，Want to reduce invalid information，And handling error information。This time on SQL Server，There will always be an error message like this：
應用程式特定 權限設定無法將含有 CLSID {806835AE-FD04-4870-A1E8-D65535358293} 與 APPID {EE4171E6-C37E-4D04-AF4C-8617BC7D4914} 之 COM 伺服器應用程式的 本機 啟用 權限授與來自位址 LocalHost (使用 LRPC) (在應用程式容器 無法使用 SID (無法使用) 中執行) 的使用者 NT SERVICE\SQLSERVERAGENT SID (S-1-5-80-344959196-2060754871-2302487193-2804545603-1466107430)。您可以使用元件服務系統管理工具修改此安全性權限。
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。
