Computer Certificate Request Problem

The root CA (A Windows 2003 SE server) in my domain crashed and had to be restored from backup.  During the process the cert service had to be removed and re-installed.  Although the cert server seems to be working now (I can access the web enroll site, and "user certs" can be successfully requested), I cannot successfully request a computer certificate on any WinXP client using the certificates mmc - every time I try I get this message from the Certificate Request Wizard: "The certificate request failed.  The parameter is incorrect".  As I mentioned before though, this seems odd because when I request USER certificates using the certificate mmc, I have no problem.  I thought it might be a problem with the computer account on this particular client machine, so I deleted if from the domain and rejoined, but the problem persists.

Any ideas?

Was the old certificate imported with private key or was a new certificate and keyset generated when you reinstalled certificate services?

I did not do any of those things before I reinstalled certificate services.

FYI: I have now uninstalled cert services from that machine and installed it on another.  Unfortunately that didnt fix the problem however, as I now get a new error message:

The certificate request failed because of one of the following conditions:

-The certificate request was submitted to a Certification Authority (CA) that is not started
-You do not have the permissions to request certificates from the available CAs.

I also performed a certutil /dump on the XP machine (See below) and I noticed there are two entries there, one with the old, original CA and one with the new.  Seems like the client is trying to contact the original (now defunct) CA for computer certificate requests.

Where should I go from here?

Try running this:
certutil -dcinfo deleteBad

How to decom a CA server properly from AD:
http://support.microsoft.com/kb/889250

If this was a root CA you will need to put the new CA cert into GPO to distribute to clients.

You can update autoenroll events for the new CA:
certutil -pulse

Use the Certification Authorities MMC to assign desired templates to the new CA and remove the old.

Great suggestions - especially helpful also was the pkiview.msc referenced in the Microsoft support article.

Thanks!
