Reset Computer accounts in Active Directory domain

February 21st, 2012 21 comments

One of our customer migrated his whole IT infrastructure into another datacenter. We powered off virtual machines at production site and powered on cloned versions of virtual machines.

Exchange ActiveSync insufficient permissions

February 19th, 2012 No comments

I couldn’t connect via ActiveSync on my account. I’ve checked events on CAS server and I found:

 

Exchange ActiveSync doesn’t have sufficient permissions to create the “CN=Zilinec Ondrej – testovaci TS uzivatel,OU=TESTUSERS,OU=UZIVATELIA,OU=XXX,DC=XXX,DC=in,DC=XXX,DC=XX” container under Active Directory user “Active Directory operation failed on DCB1.XXX. This error is not retriable. Additional information: Access is denied.

Active directory response: 00000005: SecErr: DSID-031521D0, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0

“.

Make sure the user has inherited permission granted to domain\Exchange Servers to allow List, Create child, Delete child of object type “msExchActiveSyncDevices” and doesn’t have any deny permissions that block such operations.

Here is a short script to find out the size of mailboxes in your Exchange 2010 infrastructure. This information is not visible in EMC.

Get-MailboxStatistics -Server 'mailserver' | select DisplayName, TotalItemSize | sort TotalItemSize
