Database disappears from Exchange System Manager after restore

Hi, after restoring an Exchange Server 2003 databse it fails to show up in system manager and also does not mount. However, there are three other databases on in the First Storage Group but these mount ok. The other three were not part of the ones that needed to be restored. Please assist

I should add that the message that appears in the Application log is
Event ID 9175

The MAPI call 'OpenMsgStore' failed with the following error:
The Microsoft Exchange Server computer is not available.  Either there are network problems or the Microsoft Exchange Server computer is down for maintenance.
The MAPI provider failed.
Microsoft Exchange Server Information Store
ID no: 8004011d-0526-00000000

Ideally you should have it in the RSG and the database added and restore over there ..... is this for a Production or your restoring to get some data ?

After the restore have you checked the box "This Database can be overwritten by a restore" ?

This is very IMP on the Database properties if your gonna mount from a restored database :)

The problem is this database does not show up on the Exchange System Manager so we cant change this, can it be done via registry ?

Sir if Database isnt visible in ESM not sure if its there or its a permissions issue on that Database ..... so i can try to fix it from ADSIEDIT :)

Are you comfortable with it ?

The database is there for sure in the file system, just stopped appearing after the restore. I think I have no choice, happy to try the ADSI Edit route

Find the database in ADSIEDIT and then go to its Properties and Security tab and ensure that "Allow Inheritable" is checked on it

Would this be under CN=Microsoft Exchange System Objects ?

kitsaoAuthor Commented:
I have located it but cannot view its properties and therefore cannot modify it, can I create a new object

Thanks. I believe the problem is indeed with the fact that the class attribute is missing from the database properties in ADSI Edit for this database that is not mounting. We can neither modify nor delete the entry though. How can we recreate a new one ?

Manpreet SIngh KhatraSolutions Architect, Project LeadCommented:
You can but this can be fixed so i will help you rather .... you can set this using Sties and Service console ....

Enable Show Service Node and do the same we did in ADSIEDIT and get to properties of the Database and Security tab and check the box for Allow Inheritable :)

Thanks Rancy. I eneded up doing an offline restore to another server and was able to mount the database, only that now even though im able to move mailboxes from one server to another, the moved users are not able to connect to the newly moved mailboxes. I guess I have to ask a new question so context is not lost. Many thanks though

I installed a new server and restored a backup and was able to access the database so do not really know what would be the solution to the original problem
