Eseutil /k Exchange 2010
I was unable to do a full backup on my Exchange server 2003. The error I've got in my CA Brightstor ArcServe V9 is "E8602 Failed to read from database --EC= Backup Agent Error --(69) Read/Write error in named pipes". So I use eseutil.exe /k to check the database of my Exchange server, I got this result:File: d:\program files\exchsrvr\mdbdata\board.edb Checksum Status (% complete) 0 10 20 30 40 50

This is probably preventing online backups from running, too. First of all, here is a really good article that will help you understand what is (or may have happened) to your database.

Home » » How to resolve Exchange ESE event 476 error code 1018? EDB database is the core of Exchange Information store. It consists of storage groups that contain the Mailbox Store and a Public http://recover-email.blogspot.com/2014/05/how-to-resolve-exchange-ese-event-476.html Folder Store. The data within Mailbox Store and a Public Folder Store are stored in files with .edb extension. Like other data files, the EDB file can get corrupted due to any of the reasons such http://www.edb-pst.net/eseutil/k.html as: virus attack, server shutdown, operating system crash, accidental Exchange Server shutdown and system hardware failure or malfunctioning Exchange database corruption can be of three types: • page level (file system) corruption• database level (JET checksum error database engine) corruption• and Application level (Exchange information store) corruption What is Exchange ESE event 476? ESE event 476 occurs when the page contains no data or there is some checksum error on a database page. Generally, ESE event 476 indicates two errors: Error -1019 & Error -1018. The ESE event 476: Error -1018 = 0xfffffc06 = JET_errReadVerifyFailure = Checksum error on a database page.Error -1019 = 0xfffffc05 = JET_errPageNotInitialized = Blank checksum error on database page.Error -1018: It indicates Checksum error on a database page. Error -1019: It indicates that an invalid page number (usually all zeros) has been returned by the accessed page. It occurs in when a read attempt is made on a Blank database page or if it's uninitialized. The Error -1019 can also occur if the logical link between the pages isn't valid. Note: if a page with page number 0x00000000 generates some Checksum error, then a -1019 error is shown instead of a -1018 error. The error -1019 may remain undetected for a longer time in case of online backup. What is Exchange ESE Error 1018? 1018 is a Read Verify Error. It indicates file level / page level corruption in the Exchange database. The error 1018 occurs if there is some page inconsistency in Exchange Mailbox Store. If a particular page from the database couldn't be verified then this error will be prompted. This error usually occurs while full backup of exchange is taken. What causes Exchange ESE Error 1018? ESE engine plays a vital role in handling the database operations in Exchange. When a page is requested the ESE engine search it in database. Compare the page number and the page checksum with the page header information. It then check
header damage that may occur in database, patch files, checkpoint files or transaction log files. Exchange ESEUTIL Checksum Mode performs test on the information store database to detect the checksum integrity of log files when the entire database is dismounted in the storage group.
