I am trying to set up the following environment: Standalone Root CA and Enterprise Sub CA, both running windows 2008 R2 core.

 

To set up the ROOT CA i have done the following:

Install the Certificate Services Roll by typing the following at the command line:

Cscript C:\Windows\System32\setupca.vbs /IS /sn RootCA /sp "RSA#Microsoft Software Key Storage Provider" /sk 2048 /sa SHA256 /SV 20

Run the following commands on the ROOT CA to set the issuing validity period to 20 years

 

certutil -setreg ca\ValidityPeriod "Years"

certutil -setreg ca\ValidityPeriodUnits "20"

net stop certsvc & net start certsvc

 

Install the CRL List in Active Directory by running the following commands

Certutil setreg ca\DSConfigDN CN=Configuration, DC=Test,dc=local

Certutil setreg ca\DSDomainDN DC=Test,dc=local

Net stop certsvc & net start certsvc

Certutil dspublish f C:\windows\system32\CertSrv\CertEnroll\Root CA.crl

 

For the SUB CA I run the follwoing command:

 

Cscript C:\Windows\System32\setupca.vbs /IF /sn Sub CA /DN DC=DC=Test,dc=local /sp "RSA#Microsoft Software Key Storage Provider" /sk 2048 /sa SHA256 /OR "C:\CA\SUBReq.req"

 

I then submit the request to the ROOT CA and subsequently issue the pending request. When I try to accept the response using the certreq -accept command I get the following error:

Certificate Request Processor: Cannot Find object or property

and of course the SUB CA will not start as it does not have a vaild certificate.

 

I have even tried to create a new certificate and although i can import it using the certreq -accept command the service will not start correctly.

 

Any help would be appreciated...

 

Thanks in advance

Are you sure this is correct?

 

/DN DC=DC=Test,dc=local

 

It should be:

 

/DN DC=Test,dc=local

 

Maybe I'm wrong... but this is my only idea.

That is a typo by my part...i do in fact have /DN DC=Test,dc=local

So I think your problem is the private key, in some way Windows cannot find it anymore and so cannot associate the pair.

 

I found this article, http://technet.microsoft.com/en-us/library/dd362655.aspx but it is useless because you need the GUI in order to proceed. No idea, sorry.
