Hi,
I have RDS enabled on Win 2016 R2 Datcenter. I have 2 servers, one runs every role and the other is only RDSH. Everything was working fine, but the server started logging these events in the event log:
Log Name: Microsoft-Windows-TerminalServices-Gateway/Operational
Event ID: 103
The Remote Desktop Gateway service does not have sufficient permissions to access the Secure Sockets Layer (SSL) certificate that is required to accept connections. To resolve this issue, bind (map) a valid SSL
certificate by using RD Gateway Manager. For more information, see "Obtain a certificate for the RD Gateway server" in the RD Gateway Help. The following error occurred: "2148073494".
This is strange because the certificate is not expired and it was working fine, so there is nothing wrong with ther certificate.
The second event which is logged is:
Log Name: Microsoft-Windows-TerminalServices-SessionBroker/Operational
Event ID: 2056
Task Category: RD Connection Broker Database Plugin
Level: Error
User: NETWORK SERVICE
Description:
The Remote Desktop Connection Broker server could not enumerate the targets for the provider named NULL from the database.
Pooled virtual desktop collection name: NULL
Error: Logon to the database failed.
I added the RDS server to "Windows Authorization Access Group" as suggested by some folks but it did not help.
