An error caused a change in the current set of domain controllers……

Filed under: General — telnet25 @ 4:21 am

If you are in the middle of migration and after decommissioning couple domain controllers and start having similar problems listed in this blog keep reading it. Some of the finding listed here may save you a support call to PS (-:

You have successfully decommission some of the domain controllers yet exchange is still complaining about it.

image

possible cause:

  • Check DNS to make sure name servers tab , the old DC is not listed there , if there is delete the record.
  • Check DNS to make sure there is no A record pointing to decommissioned DC if there is , delete the record.
  • Make sure TCP/IP properties on the exchange server configured correctly and pointing to valid DC/DNS/GC server.
  • If you are receiving fallowing or similar errors upon opening EMC

  • An error caused a change in the current set of domain controllers it was running the command “Get-FederationTrust”
  • HTTP server status WinRM….

image

  • The profile you logged into Exchange server might be causing these issues, log out , log back into DC with another admin credentials and delete the profile giving you above errors. ( roaming profile). Let’s say you have account called Exadmin and this account has been used to log into exchange server. You need to delete the roaming profile for “Exadmin” and on first logon Windows will create new roaming profile
  • On the Exchange server open EMC click on “Collect organizational Health data

image

Go to event logs and under application logs make sure there are no more errors

Error: Mailbox database contains one or more mailboxes arbitration mailboxes…….

Filed under: General — telnet25 @ 4:42 am

If you have completed Exchange 2010 installation and opened EMC right after it, you should be facing with default databases with some random number as shown below…

image

Now if you are like me this will not make you happy and you will want to rename this DB something will make more sense to you, such as DB1, however you will realize you cannot change the name of the DB and this will drive you nuts each time you open EMC (-:, so let’s nuke it and create another one.

  • Now just fallow simple steps , Open EMS ( Shell)

Figured out the name of the databases, you need to create least one more since you will move users from this DB into another one and delete is once there is no mailbox in the first database.

Get-Mailbox -Database

image

Get-Mailbox -Database db1 -Arbitration | ft -wrap -auto

image

 

New-MoveRequest -Identity "DiscoverySearchMailbox {D919BA05-46A6-415f-80AD-7E09334BB852}" -TargetDatabase DB2

image

***Pay attention little carrots and semi columns are going to make difference , so you have to use exactly same name on the New-MoveRequest CMDLET***

  • You can use notepad to prepare the CMDLET

Get-Mailbox -Database db1 | ft -wrap –auto

Exchange 2010 Installation in 3 STEPS!!!!!!!

Filed under: General — telnet25 @ 2:35 am

Those of you who has least done once Exchange installation will recall, preparation for Exchange install has always been serious business. Exchange 2010 has gone far beyond other versions in term of installation and here are simple steps and the link you will need to get the work done.

If you try to run setup with no preparation here are the warning you will get, in this example we will install Exchange 2010 with fallowing roles, MB,HTS,CAS into existing Exchange 2003 SMTP domain.

  • Update AD Schema

 

Summary: 5 item(s). 2 succeeded, 3 failed.

Elapsed time: 00:00:26

Error:

The Active Directory Schema is not up-to-date and Ldifde.exe is not installed on this computer. You must install Ldifde.exe by running ‘ServerManagerCmd -i RSAT-ADDS’ or restart setup on a domain controller.

Error:

The Active Directory needs to be prepared for Exchange Server and Ldifde.exe is not installed on this computer. You must install Ldifde.exe by running ‘ServerManagerCmd -i RSAT-ADDS’ or restart setup on a domain controller.

Warning:

Setup is going to prepare the organization for Exchange 2010 by using ‘Setup /PrepareAD’. No Exchange 2007 server roles have been detected in this topology. After this operation, you will not be able to install any Exchange 2007 server roles.

How to Migrate Exchange 2003 to Exchange 2010

Filed under: General — telnet25 @ 2:29 am

We will talk about upgrading from Exchange 2003 to Exchange 2010 in premises. This article will assume you have existing exchange 2003 server in your messaging environment and will talk about high-level steps going forward.

Your environment could be multi role exchange environment or clustered servers or even a single server. The process of upgrading from Exchange 2003 to Exchange 2010 is fairly same and simple and much less complicated compared to Exchange 2007 migration scenarios in my opinion.

Task 1

  • Decide your hardware, your Disk type, Memory, CPU requirement based on your needs. The basic printable for deploying exchange servers are still the same
  • Calculate your IOPS and future growth
  • Install adequate memory on the new Exchange servers, Memory prices are not the main factor these days , more memory is better ( 8,16,24,32 Gig memory)
  • CPU requirements , use MS guidelines and same goes for CPU the more power is better for your Exchange servers
  • Disk type and local storage requirements, JBOS ( no RAID, just bunch of disk) , If you are going to take advantage of new redundancy futures perhaps you will look more into DAS ( direct attached storage) or go JBOD RAID less.
  • Most likely this is ( DISK) where the price difference will come into play, at least no more SCSI expensive disk is required, SATA disk are most preferred disk type for small and large deployments. DELL, IMB and other hardware vendors do have DAS (direct attached storage) you may want to explore to see what options you have.
  • RAID type is one of the most asked questions, remembers Exchange 2010 is above %50 percent faster in speed to compare to Exchange 2007 and somewhere 150 times faster compared to Exchange 2003. (These are round numbers). The fastest read and write you can provide to Exchange 2010 is better with utilizing SATA disks as general rule and yes how much redundancy you wish to have it up to you as well. For instance utilizing one exchange server 2010 with DAS configured in RAID 10 seems to be valid option. SATA disks are cheap compared to SCSI drives.

You need to decide what hardware to use or what type of configuration you will use to move forward with Exchange 2010. I am sure you already heard about lowering the cost and making Exchange redundant by utilizing (DAG) or maybe you will deploy single server. Sizing your hardware and making up your mind for hardware redundancy is entirely optional, as budget constrains effects such decisions.

Summary:

  • Install New Exchange 2010 server into existing Exchange org.
  • Replicate all Public folders and its entire content to Exchange 2010
  • image
  • Use mailbox move wizard to move some pilot users
  • Test mail ( inbound and outbound ) for the pilot users
  • Configure and test OWA, outlook anywhere etc. on the exchange 2010 server
  • Schedule to move rest of the users from Exchange 2003 to Exchange 2010
  • Change mail flow inbound and outbound SMTP traffic to Exchange 2010 server
  • Stop all exchange related services on Exchange 2003 server and make sure everything is working, if you encounter problems, turn the services back on and find out what did you forget to do.
  • image
  • Delete all mail stores, databases from Exchange 2003 server.
  • image
  • Shut down Exchange 2003 server for couple days to make sure everything is working.
  • You may forget receive fallowing errors and warning when you ready to remove the exchange server from windows 2003 server.
  • One or more users currently use this mailbox store. The users must be moved to different store or be mail disabled before deleting this store. ID no c1034a7f, exchange system manager. You don’t see any mailboxes but there are objects in AD which are pointing to Exchange server you are trying to decommission
  • Now we need to find out which object is still has a partial information pointing to this exchange server we wish to remove from out Mail organization

image

 

Lets fire up, ADUC  on the Exchange 2003 server.

  • Start run
  • Dsa.msc
  • Right-click the domain container, and then click Find ( or click on the find icon on top left)
  • Select the Advanced tab
  • Select User from the Field button
  • From the list of attributes displayed, choose Exchange Home Server
  • Set the Condition field to Ends With
  • Enter the Exchange server name into the Value field ( server you are trying to get rid of)
  • Click Add
  • Click the Find
  • Make a right Click and Delete all those found in the search
  • image
  • Go back and kick of uninstall process one more time
  • you may receive warnings for routing group connectors and routing group master as the old exchange 2003 is the only server and un-install wizard wont move head. You may need to use ADSI edit to delete the routing group connector etc (Warning , ***make sure you understand what you are deleting, ADSI edit is serious tool and wont have tolerance if you delete the wrong information, so be Extremely careful****

Finally Un-install wizard will let you move on and last you need to point the uninstall wizard to Exchange 2003 binaries location or the install CD in order to finish.

Take a look
