1.5 Click Finish















1.6 Click OK

1.7 Expand Certificates Node and right click Personal -> Certificates -> All Tasks -> Import

1.8 Click 'Browse' to select correct Certificate file and click Next

2. Click the imported certificate, in the 'Details' option, scroll down to the Thumbprint field and copy the space delimited hexadecimal string into a .txt file

3. Remove all spaces in the string from the .txt file

Note:  You'll also want to watch out for and remove a non-ascii character that sometimes gets copied just before the first character in the string. It's not visible in Notepad. You may see it when you running the commend in the next step 4.

4. At command prompt, run the following wmic command together with the thumbprint

wmic /namespace:\\root\cimv2\TerminalServices PATH Win32_TSGeneralSetting Set SSLCertificateSHA1Hash="d4274aea12dbfff5c11c389d8c7d1f23e76932cf"
If the cmd command does not work, you can also use the following powershell command:
$TSGS = Get-WmiObject -Class "Win32_TSGeneralSetting" -Namespace "root\cimv2\terminalservices"
Set-WmiInstance -Path $TSGS -Arguments @{SSLCertificateSHA1Hash="d4274aea12dbfff5c11c389d8c7d1f23e76932cf"}
RDP Certificate can be easily set via tool

1. You need to use your certificate name rather than your server IP to connect to your server.
2. The certificate name must point to the server IP.
