How to resolve SSL error "A specified logon session does not exist. It may already have been terminated. (Exception from HRESULT: 0x80070520)" on IIS

When attempting to bind an SSL certificate to a website, you get the error : "A specified logon session does not exist. It may already have been terminated. (Exception from HRESULT: 0x80070520)"

The most likely cause of this error is a private key not being installed for the SSL certificate.

This means that the "Mark Exportable" check box was not selected when importing the SSL certificate. To resolve this issue, re-import the SSL certificate from MMC certificate console and make sure the "Mark Exportable" check box is selected.

Remove logs or Entries from the Remote Desktop Connection

I found that most people have no idea how to delete a cached entries from Remote Desktop Connection (RDC) on a Windows OS based computer. In fact, I had no clue how to do this. Even after you log out and select delete profile from the RDC, it will still show up in the Connections drop down next time someone open it. This is a problem because if a user with wrong intent to attack your computer or server open the RDC, it will provide them with half of the solution to hack your system, the IP or domain name!

I have no idea why a great user friendly software company like Microsoft doesn't explain well on their help sites on registry editing for intermediate to advance users. May be because they don’t want novice users to pick up that information from their site and damage the OS in the process of regedit. Yes, it include the path and how to edit it, but there are no clear cut step by step instructions on how to properly do it.

The following method is the easiest way to delete an entry from Remote Desktop Connection:

-Open regedit: Type regedit on the general search (on the start menu) of the computers running Windows Vista and up. If you have a older OS, then open Run, and type regedit.exe.

-Find this parth: Go in to the Terminal Server Client using, HKEY_CURRENT_USER–>Software–>Microsoft–>Terminal Server Client–>Default

-Delete the entry: You will see all the entries with their respective IP address or domain names recorded on the system history. Pick the one you want to delete and hit delete on your keyboard OR right click and delete it.

Make sure you close the regedit.exe BEFORE you open the RDC because this change may not reflect on the client.

Now you will not see the entry in the RDC client when you open it the next time.
