Dear
In my root domain server, three errors occurred in Application log
Event ID 256, Cryptography service failed to initialize the Catlog Database, Access is denied
Event id 257, Cryptography service failed to initialize the Catlog Database, The ESENT error was:4001
Event ID 412, Unable to read the header log file
I have tried to repair the catroot2, as mentioned in following article , verification checked was successful and found no integrity error
http://social.technet.microsoft.com/wiki/contents/articles/13827.windows-server-2008-event-id-257-system-catalog-database-integrity.aspx
The only error i have seen that in logs is -528 (log file is missing ), i checked at %systemroot%\system32\catroot2 the ebd.log is not there , however other files like edb600a, .... edb700A.log exist, However when i tried to open latest log file i.e. ebd0007A.log file , access denied error is occured.
because of this access denied, i cannot follow the instruction to create new Folder Catroot2.old as mentioned in the article.
I have also disabled my antivirus on this sever.
Require a help in this regard
