How to add a Subject Alternative Name to a secure LDAP certificate

This post describes how to add a Subject Alternative Name (SAN) to a secure Lightweight Directory Access Protocol (LDAP) certificate. The LDAP certificate is submitted to a certification authority (CA) that is configured on a Microsoft Windows Server 2003-based computer. The SAN lets you connect to a domain controller by using a Domain Name System (DNS) name other than the computer name. This article includes information about how to add SAN attributes to a certification request that is submitted to an enterprise CA, a stand-alone CA, or a third-party CA.

DAG FSW is empty - Getting "The cluster resource could not be found" when try to manage Failover Clustering

I couldn't find way of make the DAG to recreate the files on its File Share Witness, every trying was unsuccessful.

When I tried to remove the servers from DAG to recreate it I recieved an error because the cluster couldn't find the quorum. I decided to try a not good way to solve the problem, but using the following steps I could have the DAG working fine.

1- Removed every server from DAG using Remove-DatabaseAvailabilityGroupServer -Identity -MailboxServer -ConfigurationOnly

2- Cleaned the cluster using this command to every DAG member cluster node /forcecleanup

Done, now you can delete the DAG and recreate it.

Unable to mount Exchange 2007 database

After restoring an Exchange 2007 server from a backup to a test ESXi VM I was unable to mount the Exchange mailbox database:

Failed to mount database ‘Mailbox Store’.

Error:
Exchange is unable to mount the database that you specified. Specified database: SERVER1\First Storage Group\Mailbox Store; Error code: MapiExceptionJetErrorAttachedDatabaseMismatch: Unable to mount database. (hr=0x80004005, ec=-1216)

To fix this I used:

eseutil -p “Mailbox Store.edb” 
eseutil /r E02 /i

(in the directory that contains the database)

!The first command is said to be able to cause the loss of data. So only run this on a backup database!

Mailbox doesn't appear on Disconnected Mailbox after disabling it

Sometimes when you disable a mailbox you click o Disconnected Mailbox and can't see the mailbox that you've just disabled.

To see the hidden disconnected mailbox run the following cmdlet on the mailbox server that hosts the mailbox:

Clean-MailboxDatabase “Database Name”

After running the cmdlet return to EMC and refresh Disconnected Mailbox, then you'll see the mailbox there.

Using Import/Export-Mailbox on Exchange 2010

By default you cannot see the cmdlets import-mailbox either export-mailbox. To enable the Exchange Management Shell to use these cmdlets you need to run this command to allow a specific user:

New-ManagementRoleAssignment –Role “Mailbox Import Export” –User “Rodrigo”

or you can enable a group:

New-ManagementRoleAssignment –Role “Mailbox Import Export” –Group “MailboxAccessGroup”

After running one of these cmdlets restart the Exchange Management Shell to use the "hidden" cmdlets.
