Hi Someone changed the permissions on the server/mailstore in exchange system manager. After restarting we can not see our server under servers in exchange system manager, instead I get the error; "There is no such object on the server, Facility: win32, ID No: c0072030, Exchange System Manager". Also we are getting events 1038, 9149 and 1005 in the system event log. I am trying to follow steps in article http://support.microsoft.com/default.aspx?scid=kb;en-us;325674 but at step 6 when I click on my server name and click on properties I get a message 'An invalid directory pathname was passed.'. Any idea how I can fix this problem? Thanks Regards
