The Exchange Server could not initialize the jet engine system database not found has a built-in facility which helps in determining and fixing any damages which that take place

JET_errReadVerifyFailure error (probably during online backup creation). Depending on what went wrong, the Exchange ServerDatabase may get corrupted at various different levels. For instance, at times the index is dis-ordered or the EDB file is corrupt. Based on the type https://social.technet.microsoft.com/Forums/windows/en-US/1973da99-e3aa-4d0d-83c6-846568c3364b/directory-services-could-not-start?forum=winserverDS of failure, DB corruption of Exchange Server can be classified as Logical Corruption and Physical Corruption. Resolve Exchange 2007 Error 1018 from Physical Corruption Meanwhile, to verify the file-system damage to database, one can use Eseutil. All you need to do is to apply the/mh switch. It will automatically scan the header of the DB for the point where checksum value stability determines integrity of the database.

For a layman user, Exchange Database looks like yet another system-file saved with .edb file extension. However, at the logical level, an EDB file consists of 4KB pages (or even multiples 4KB, depending on the OS and the version of Exchange in use). In order to keep the I/O operations minimal, these pages are organized in a B-tree structure. Some of these pages might contain data while others may have pointers which link one page to another. Having such a structure ensures that once a query is raised, traversal is faster and you obtain quick results. Further, indexes and tables manage data using a separate B-tree structure, which is called B+ tree. The header occupies the first two pages of Exchange database EDB file. This means the first logical page of the database is indeed its third physical page. Mentioned below is the formula which helps you in calculating the Logical Page number of EDB file: The checksum value of database is as important as its page numbers. While writing transaction to the disk, a mathematical calculation takes place. This calculation for the page is known as Checksum. The header of EDB file holds this value and when the database is read, either while creating online backup or while performing a general task, this value is calculated all over again. If both the values, the one stored in the header and the re-calculated on
lab environment my Windows 2008 R2 Domain Controller VM did not start. When booting the VM I got a BSOD with a STOP error: STOP: c00002e2 Directory Services could not start because of the following error: a device attached http://martijnwestera.blogspot.com/2013/01/stop-c00002e2-directory-services-could.html to the system is not functioning.

This was my only Domain Controller and no backup so I had to solve this problem. Troubleshooting steps: 1. Boot into Directory Services Restore Mode (F8) 2.

Messed with this for like 3 hours and your post is short and to the point. Thank you!!ReplyDeleteAnonymousFebruary 11, 2013 at 2:17 PMBrilliant! I did a v2v (form ESXi to MS) of a 2008 DC using imaging software and ended up with this exact issue, after trying just about every recommendation around, this is what resolved it for me, It turns out i had the same issue with DFSR and WSUS DB's, renaming the logs sorted them out too.It also seemed to kill all my exchange DB's which didn't appreciate having the logs removed, so in the end I rolled back and looked at other options to migrateYour post was very

File-level damage to your Exchange database can manifest itself in errors such as the -1018, -1019, and -1022 Joint Engine Technology (JET) database errors. First (and most common) is the infamous -1018 error. This error most often rears its ugly head during a full backup of Exchange databases. The error's Detail field shows that the -1018 is a Read Verify Error. Simply put, the database engine tried—and failed—to verify information about a particular page in the database. (When the Extensible Storage Engine—ESE—reads a page from the database, it compares the page number and the page checksum—which are located in each page's 40-byte header—and verifies that the page requested was the page returned and that the page's checksum is valid. To calculate the checksum, the ESE uses a seed value, then XORs that value with the data in the page.) The -1018 error can have many causes, which I've discussed in past commentaries. More important than the cause, however, is how you decide to recover from it. You really have only three options. The first option is to restore the database from backup. This option is the most drastic but might be the only solution if other methods fail. The second option is to use Eseutil (which comes with Exchange 2000 Server and Exchange Server 5.5) to attempt to repair the problem database. Be aware, however, that this method is likely to cause some data loss. (This method essentially eliminates the bad pages in the database; the severity of data loss depends on what information those pages stored.) The third option is data relocation. I pre
