Issuing CA Certificate Template + capolicy.inf problem

Hi,

I have already built a Windows 2008 R2 Intermediate CA and configured a custom Subordinate CA template.  Now, I am trying to build a 2008 R2 Issuing CA and running into all sorts of problems.

First, I installed the CA role and that worked fine.  However, instead of automatically getting a certificate from the Intermediate CA, it generated a .req file instead.  I searched my issue online and was told to add:

[RequestAttributes]
CertificateTemplate=MyTemplateName

to the capolicy.inf on the Issuing CA.  So I uninstalled the role, added those changes and tried to reinstall the role.  Now, what happens is that MMC crashes during the installation and in my Event Viewer, there is an error:

Event 100, Application Error
Faulting application name: mmc.exe, version: 6.1.7600.16385...
Exception code: 0xc0000374
...

I googled for the problem on this as well but there were no solutions that applied to me (I don't have SQL or Office installed).

So, I decided to try something else.  I removed the two lines that I added to the capolicy.inf file and tried to see if I could install the role again.  That worked!

So it seems to be some kind of problem with contacting the Intermediate CA?  Is there a setting that I need to make in order to make this work?

Thanks so much for your help.
