Now all I needed to was to loop through all the servers, I did this by setting up a file with all the servers listed in it. Then created two batch files one to loop through the server list and pass each server to the second batch file which contained the psexec statement above.

This command loops through the serverlist. Windows, I found that the certutil for windows moaned about the —p parameter.

On the TechNet forums, I found that I had to export the cert again from my current Exchange server that I need it on, and exported it with a private key this time.

If so, did go back to IIS and complete the request? Actually have done it both ways. Same thing. I'm actually doing the same process for my sql server now.

Wondering if it's a bug. Same tech. OK, if you used IIS and completed the request, you "should" then see a certificate with the personal certificate store with the key on the icon indicating the private key is there.

There should be no need to repair it. If you open up MMC and the certificates snapin then choose computer account, do you see the certificate there in the personal store?Need support for your remote team? Check out our new promo!
