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。
The original Unifi Network Controller is installed on a Windows 7 Computer，Recently, I feel that the frequency of stopping the Controller is a little too high，I have to restart the program almost every day，Go online and find that there are official instructions to set the program as a service to run，But after the actual test，The service cannot start，Read the instructions carefully，Windows 8 Or Windows 10 Only，So simply find another Windows 10，And move the Unifi Network Controller。
SQL Server will run out of operating system memory by default，And on the server dedicated to SQL Server，In general, it is also recommended to use the memory as much as possible for SQL Server，One to improve efficiency，Secondly, it also reduces the IO loss of the hard disk。However, if there are specific circumstances that need to control the memory limit of SQL Server，SQL Server Management Studio (SSMS) To achieve。
Some time ago, the Synology NAS had a few TB less space，Later, according to official teaching，Connect to the system via SSH to view，Only found out that it was the trial CloudStation directory，Generated a huge amount of data，Because it's just a trial，The function does not meet my needs，Later it was removed，And manually remove the hidden @cloudstation folder。
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。
Several years ago, I searched the Internet for Evernote solutions in Linux，At that time, the OS was Ubuntu，The result found is that the official said that there is no plan to develop，The alternative that the community can find is only NeverNote，But the interface of NeverNote is really not used to it，So later I used the web version of Evernote。After repairing Manjaro recently，I searched the Internet again to see if there were any new solutions，Results found Tusk，Tusk's interface is almost exactly the same as Evernote，Even the way to drag the notepad，Whole heart。
When updating Manjaro today，Keep jumping out “nss：/Usr/lib/p11-kit-trust.so already exists in the file system” mistake，Later tried the following instruction method (sudo pacman -Syyu) The result is the same，上網查詢，The result is normal，Because of some errors in the old version，So when updating，Need to add parameters to force coverage。
