I had performed NTBACKUP of my Exchange 2003 server and it has returned the following error.
" Backup started on 6/27/2015 at 2:40 AM.
The 'Microsoft Information Store' returned 'Instance not found
' from a call to 'HrESEBackupSetup()' additional data '-'The 'Microsoft Information Store' returned 'Functions called in an invalid sequence.
' from a call to 'HrESEBackupClose()' additional data '-'
The operation was ended."
How to resolve this issue as I dont have any good backup of the same.
