COM error while submitting certificate request

Hello there

I have created a group and assigned Read, Issue and Manage Certtificate, Manage CA & Request Certificate permission on the CA.When any member of this group try to sign a certificate request, the following error accours.

Your request failed. An error occurred while the server was processing your request.

Contact your administrator for further assistance.

" type=button

Request Mode: newreq - New Request

Dis"font-size:9pt;">(never set)

Disposition message: (none)

Result: The RPC server is unavailable. 0x800706ba (WIN32: 1722)

COM Error Info: CCertRequest::Submit: The RPC server is unavailable. 0x800706ba (WIN32: 1722)

LastStatus: The operation completed successfully. 0x0 (WIN32: 0)

Suggested Cause: This error can occur if the Certification Authority Service has not been started.

During this time event ID 10016 is logged on the eventlog

The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID
{D99E6E73-FC88-11D0-B498-00A0C90312F3}
and APPID
{D99E6E74-FC88-11D0-B498-00A0C90312F3}
to the user <Domain>\<Username> SID (<SID>) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

I have assigned the required permissions to the group on CertSrv Request. Also verified the membership of Certificate Service DCOM Access.

Can you please help me to resolve this?

Thanks

Hi Ranjith,

I suggest you restart the certificate services and try to enroll certificates to test if the Certification Authority is functioning.

In addition, please make sure that ports in the blogs below are open:
