[thisis4115]

new member: Register Hi All,Office Ultimate 2007 Key, I have installed Community CA (Microsoft) . On the time of installation,Office 2010 Discount, it had been doing work fine. Instantly immediately after one week,Windows 7 Home Basic, CA services is stopped and when tried using to get started on the service it displays the error : "KeySet does not Exists 0x80090016(-2146893802)". I checked the Event Viewer also. In Event Viewer Error is as follows: Source :certsvc Event Id :100 Explanation : Certificate services did not start out: could not load or verify the current CA certificate. <CA Name> Keyset does not exists 0x80090016(-2146893802). Currently I have reinstalled the CA and now it is functioning fine again. Can anyone help me in this regard? what can be the reason? I've not done any changes. Regards,Microsoft Office 2010 Pro, Anu
