Hello, I am having trouble with a newly purchased SSL cert from Symantec. The cert is for a Windows Server 2008 R2 server for securing RDS connections. I used the Symantec SSL assistant to generate a CSR and selected ECC encryption (this may be the root issue).
When I received the SSL cert from Symantec I used the Symantec install assistant to install cert on server. Then using the Server certificate console I exported the cert to a .pfx cert.
In the RD Gateway Manager I completed the following steps to import cert.
1. Import a certificate into the RD Gateway "server name"
2. I browse to the "myserver.domain.com.pfx" cert
3. Entered private key password (created when I exported cert)
4. Message: The Certificate "...." was successfully imported to the RD Gateway server
5. I click OK on the successfully imported message and then click Apply on SSL certificate tab
6. Message: To set the new certificate, you must restart the RD Gateway service......
7. I click on Yes and the following error message is displayed:
The certificate cannot be set in Internet Information Services (IIS).
There are two district errors in the TerminalServices-Gateway log:

Description:
The server certificate is not valid because the public key of the certificate contains an object identifier (also known as OID) of 2.5.29.15, but does not support the Extended Key Usage (EKU) for encryption. For the "Request clients to send a statement of health" setting that is enabled on this RD Gateway server to function, if the certificate that you plan to use contains an OID of 2.5.29.15, you must ensure that one of the following key usage values for this certificate is also set: (1) CERT_KEY_ENCIPHERMENT_KEY_USAGE (2) CERT_KEY_AGREEMENT_KEY_USAGE (3) CERT_DATA_ENCIPHERMENT_KEY_USAGE. For more information, see "Obtain a certificate for the RD Gateway server" in the RD Gateway Help.
Has anyone encountered this issue before? Any assistance or guidance will be greatly appreciated.
