Hi Sandeep,
I am requesting the certificate from the same CA server.
Do you mean that you are requesting certificate from the CA itself?
Are you trying to request certificate through MMC?
I suggest you check whether the CA’s A (host) record is present in corresponding DNS zone.

Hi,
I am requesting the certificate via web browser.It's a Standalone CA.
Previously I created and issued the certificates for some of the server but now while submitting the new certificate request it's giving error.In event log also not giving any error.

Hi Sandeep,
Here are a few suggestions for you:
- Log onto the CA, check whether Remote Procedure Call services (including RPC and RPCLocator services) are running, if not, start them manually.
- Ensure ports TCP 135 and randomly allocated high TCP ports are not blocked, or you may temporarily disable firewall on the CA to test.

I hit this error too. Hopefully someone can benefit from how I addressed it.
After requesting a new cert over web enrollment I also got the error.
CCertRequest::Submit: The RPC server is unavailable. 0x800706ba (WIN32: 1722 RPC_S_SERVER_UNAVAILABLE)
Without going into all the detail of DCOM permissions you need to ensure you are accessing the Certificate web server remotely and not locally from the CA server.

Michael... You are the man!!!!
WOWOWOWOWOW... I've been searching for a week for this issue... I couldn't figure out where my mistake in the configuration was This is simply ridiculous....
Why wouldn't it work locally everything else works that way from the CA... I'm pretty sure I've tested CA requests locally on 2008R2 without issues... is this an issue with 2012R2 ?
Wowowowow I cannot thank you enough... I was ready to blow up everything for the 5th time... (working with an Offline CA, including a Enterprise Sub. makes it a little more work, but these stupid little errors make you question all your work...)
Thanks again everything is working just as it should.

Glad it helped G-EDGE.
You asked why it works remotely and not locally. I'm doing this from memory and I can't even remember putting in that post (7 months ago). But from what I recall its permissions on the DCOM object.
Open an MMC console and add the Component Services snap-in. OPen Component Services and DCOM Config. Then find the CertSRV Request. Check the Properties, Security and Access Permissions. There are separate permissions for Local and Remote access.

Another vote that Micmaher has the correct answer. Do not use IE on the CA server itself, use IE on another system.

Micmaher thanks a lot. Was trying from teh CA server also. Got to work it out on the mail server and all went fine.
Thanks.
