How to generate a CSR for Microsoft Office Communications
After you have installed Office Communications Server 2007
(OCS) click Start -> Programs -> Administrative Tools ->
Office Communications Server 2007
Expand the items in the snap-in until you get to the
Enterprise Edition Server that you installed.
Right-click on the correct server name and select
"Certificates". Click next to get past the Certificate
Wizard welcome screen.
Choose to "Create a new Certificate" and click
Choose to "Prepare the request now, but send it later"
and click Next.
Under "Name" enter name for your certificate. This
name is simply a label for the certificate, so you can name it
whatever you like such as the server name or the pool FQDN.
In order to export the certificate to other servers, you need
to make sure that "Mark cert as exportable" is checked.
Then click Next.
For "Organization" enter your EXACT legal company
name including Inc, LLC, etc. if applicable.
For "Organizational Unit", enter the department
such as Accounting or Engineering and click Next.
For "Subject Name" enter the exact Fully Qualified
Domain Name of the pool. Select the option to "Automatically
add local computer name", and click Next.
Enter your Country, State/Province, and City details and
Choose a file name and location to save your new Certificate
Request (CSR). The file will be a text file, so it should be given a
.txt extension. Click Save.
Review the settings and finish the certificate wizard. This
will save the CSR file to the location you entered above. While
ordering your SSL Certificate,
you will be asked to copy and paste your CSR to the COMODO order
form. Open your CSR file with notepad, and copy and paste the
contents to the order form. Select "Microsoft Office
Communications Server 2007" as the server platform.
