Question : Mailbox Store disappeared - permissions problem

I have a problem.  I was trying to run exmerge and I do not think I had the correct permissions as administrator (send to and read) to do the operation.  Anyway in Exchange 2003 System Manager I went into the permissions on the Mailbox Store and removed the "allow inheritable permissions" check.  Now the Mailbox Store does not show up in System Manager, so I cannot mount it (or anything else).   The Public Store is there.  How can I fix this - I'm pretty sure the prov1.edb and .stm files and the logs are all fine.  I have lots of backups, etc,.  Tried various restores, etc, but to no avail.  The Event Viewer shows several messages, but I think they are all caused by not having permissions on the Store.
Thank you (Sunday afternoon I need to get fixed today).

Answer : Mailbox Store disappeared - permissions problem

Ok, then do the following. Go to a domain controller and start the command line.

Type the following command:

dsacls /P:N

Replace the with the following string:

"CN=Mailbox Store (SERVERNAME),CN=First StorageGroup,CN=InformationStore,CN=SERVERNAME,CN=Servers,CN=First Administrative
Group,CN=Administrative Groups,CN=DOMAIN,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domain,DC=domain"

In the string set the correct values for SERVERNAME and DOMAIN as well as "DC=domain,DC=domain" (like DC=amazon,DC=com).

That should reset your permissions on the Mailbox Store and it should reappear in ESM.
