Certificate Services - Web Enrollment Error

[Sektor]

Hi all,

I have a problem configuring my lab with this scenario:

- Domain A

- Domain AA as child of Domain A

- Domain AB as child of Domain A

- The users are in the domain AB

- The computer, service accout, CA are in the domain AA

- The CA is an Enterprise CA

- The Web Enrollment server is not installed on the same CA server (web

enrollment server is in the domain AA)

- The Web Enrollment server is configured to use "Windows Integrated

Authentication"

I followed all the steps described in this link

http://www.microsoft.com/technet/prodtechn.../webenroll.mspx

(configuring the web enrollment proxy for delegation).

The users are the priviliges to read/enroll/autoenroll the certificate

template.

When I try to (auto)enroll a certificate using certsrv page from the Web

Enrollment server I have this error:

The RPC Server is unavailable. 0x800706ba

Any kind of help will be greatly appreciated.

Thanks.
