The DNS name is unavailable and cannot be added to the Subject Alternate name

We have a new Windows 2008 R2 domain controller in a remote site connected by VPN tunnel. All ports open between site and CA.
CA is Windows 2003 SP2 Enterprise CA.

The new DC is in DNS with all server records.

When trying to submit request to CA I get the error
Certificate not issued (Denied) Denied by Policy Module The DNS name is unavailable and cannot be added to the Subject Alternate name. 0x8009480f (-2146875377)
Certificate Request Processor: The DNS name is unavailable and cannot be added to the Subject Alternate name. 0x8009480f (-2146875377)
Denied by Policy Module

I've followed this:

I've tried this:

commands run on DC:
cscript reqdccert.vbs (script by MS - see first link)
certreq -new NEWDC.inf NEWDC.req

Open in new window


command run on CA (produces the error):
certreq -attrib "CertificateTemplate:DomainController" NEWDC.req

Open in new window

could you try to add the subject alternate name attribute on your CA before requesting your certificate?

Running the "cscript fixdctemplate.vbs domaincontroller" command (script provided by MS in link) solved the problem.

Thank you!
