Exchange 2007 cmdlets adn AD replication

Exchange 2007 cmdlets adn AD replication

I was wondering if Exchange 2007 cmdlets like set-mailbox, 
set-mailboxdatabse, etc, which writes to AD, initiates any AD repliction 
within or outside the local site? If not, how one would know which AD is 
being updated? 
One of the properties that get displayed with Get-ExchangeServer cmdlet is 
the "CurrentConfigDomainController". I was wondering if this the DC that get 
used whenever we run cmdlets. Is this a singleton value or array.

Any cmdlets to initiate AD replication?

Thanks.

Re: Exchange 2007 cmdlets adn AD replication

While Windows PowerShell does work with a lot of Windows components, and 
Exchange Management Shell built on top of it "powershell-enables" Exchange, 
Active Directory itself isn't really AD-enabled.

Any changed attributes get replicated using the normal AD replication 
mechanism and schedules - intra-Site and inter-Site. Not something you 
particularly worry about, and neither something (depending on nature of 
change) you would want to trigger replication manually. If you want a 
particular DC to get the info first, you can target most EMS commands 
against a particular DC.

That doesn't make any sense... this should be "AD itself isn't really 
PS-enabled".

RE: Exchange 2007 cmdlets adn AD replication

As I understand it - CurrentConfigDomainController is the DC that the 
Exchange server will query when it needs to access AD.  It should be 
configured to be in the same site as the Exchnage server.  When you make a 
change via set-mailbox etc  the data will be written back to AD.  It doesn't 
matter which DC really as AD replication will move that information to all 
other DCs.  The DCs in the same site as the Exchange server will be updated 
almost immediately - other sites will depend on the replication schedule.

You cannot control AD replication through the Exchnage cmdlets

For a moment, there, I thought I heard the theme from "The Twilight
Zone" in the background! :-P

RE: Exchange 2007 cmdlets adn AD replication

If there are two AD DCs in same site as Exchange server which DC is updated 
by such Exchange cmdlets. It is ALWAYS the DC that is referred by 
"CurrentConfigDomainController" value.

RE: Exchange 2007 cmdlets adn AD replication

As far as I know yes - - but remember that replication within a site is very 
quick - a few seconds by default so all DCs in the site will be updated 
almost immediately.

Just out of curiosity why the concern about which DC is being updated?

No, exchange cmdlets do not generally initiate any replication. Changing 
the password will I think but I haven't tested it to be certain.  I have 
  some code which does quite a bit of manipulation via cmdlets and had 
problems until I forced all the interaction to happen on the same domain 
controller.

You can force replication but you won't make any friends of your AD 
administrators.  I don't remember how off the top of my head if it was a 
powershell cmdlet or low level code.

Re: Exchange 2007 cmdlets adn AD replication

Any change to AD will trigger replication but it is a function of AD not the 
script or cmdlet causing the change.  Replication is an inherent feature of AD

As far as I know there isn't a cmdlet to force replication.  It can be 
scripted
