I moved a CA to a new server (following microsofts migration plan). Now, when i try to install the web enrollment i get an error: Cannot Install Certificate Authority Web Enrollment. Active Directory Certificate Services setup failed with teh following error: The parameter is incorrect. 0x80070075 (WIN32: 87) I looked this error up and it said to assign the SeRestorePrivledge to the account - which i did (through group policy)- but i still get the same error. thanks

Hi, i have exactly the same issue as mention here. I applied the patch but didn't solve it. I've read somewhere that the secuence: restore from backup > install IIS > install CA Web enrollment doesn't work but, how can it be fixed without removing iis, ca, etc. in my case it's not possible to go back (for some other circumstances we have already gone back and, let's say that i've used my last bullet on that one ...

This worked for me: Modify SetupStatus at HKLM\System\CurrentControlSet\Services\CertSvc\Configuration to 0×6001 http://www.leedesmond.com/weblog/?p=692 thx this help me

This worked for me too. Can you tell me what 6001 means? 6003 was the value prior. Thanks.

http://social.technet.microsoft.com/wiki/contents/articles/12035.certification-authority-web-enrollment-configuration-failed-0x80070057-win32-87-en-us.aspx This is because 6003 indicates that CA Web Enrollment is already installed and 6001 indicates that it is not yet installed.
