Exchange problem, DC problems, GPO fails with error.. the system cannot find the file specified
Posted on 2011-03-12
Our Exchange Server recently went bananas. Exchange Event, Information Store, MTA Stacts and System Attendant SERVICES fails to start. While diagnosing fault, I found that the Domain Controllers also had problems from Replication to DNS. We have 3 DCs. The PDC and the Exchange Server are both GCs. Now, no GC can be found. I ran dcdiag on the 3 servers. The PDC and the Exchange servers both failed Netlogons and frsevent. The PDC also failed kccevent and systemlog.
Please note that running netdiag shows that the DNS is ok on the PDC and the Exchange Server. But I find that the 3rd DC fails DNS test using nslookup.
I also found that SYSVOL was empty on the PDC. I attemped using GPMC to backup and restore the GPO which was given error.. The system cannot find the file specified. To my surprise, the backup using GPMC failed with the same error.. The system cannot find the file specified.
How do I resolve this? Do I find gpofix.exe and use it? Which of the DCs should I run it.
Urgent help needed. Thanks.
