Oranda Router service fails to initialize with invalid certificate

Article ID: 51599 - Last Review: July 11th, 2012


In Lync 5.10, the Oranda Router service will not initialize successfully on service startup.  It indicates that the certificate issued to the server is from an Invalid Provider, and just continues to repeat the error.


OrandaRouter log will show the following error repeatedly:

eError    7/9/2012 7:44:15 PM      RouterInitialization =>   An error occurred trying to get a valid certificate: Invalid provider type specified.


The server contains a certificate that has a provider that is not from a ‘Microsoft RSA SChannel Cryptographic Provider’.  In this example, it was a ‘Microsoft Software Key Storage Provider’, which the router cannot validate.  The router picks the first certificate that matches a very basic criterion; contains the name of the local host as part of the subject.  It does not move on to the next certificate once it has hit the first one.


In command prompt, run the following command:  ‘certutil –store my’

This will give the results of all certificates issued, along with all relevant information, including the Provider.  The certificate in position ‘Certificate 0’ should be a valid ‘Microsoft RSA SChannel Cryptographic Provider’. Here is an example of the output:

Invalid Provider:

So when the router hits the invalid certificate, it fails and refuses to start.  Assuming that this certificate is not required for the pF server, it can be deleted.  In this case it is the ‘8021x Workstation Authentication’ certificate, which is useless for this server as it is not using wireless connection.

Once the invalid certificate is deleted (using MMC snap-in) a restart of the prairieFyre Enterprise Router Service may be required.
