Hi Chris

I appreciate that you may have applications that don't run on Windows 2000/3 
but why does that stop you upgrading the whole Domain? You can run NT4 servers, 
even Domain controllers if you are in mixed mode, in a Windows 2000/3 AD Domain 
just fine.

Regards,

Paul Lemonidis.

  Well I did not reply because I am not knowleable enough to know the answer.



  That being as it may, it seems you could probably do it with a SMTP Connector.

  Thanks,

  Hello all,


     I am on a fact-finding mission in preparation for an Exchange upgrade to 
occur later in the year.  I was wondering if any of you can provide some 
insight.  



  Information: [in the form of a Microsoft Certification question :-) ]

     You are the administrator of an NT 4.0 network....  Currently our North 
America operations has 3 main NT 4.0 domains that are all connected via trusts. 
 The exchange infrastructure is Exchange 5.5.  We have one Exchange 
Organization and 3 different Exchange Sites (one for each domain).  Due to 
mission critical services that are ONLY compliant with NT 4.0, the current 
Corporate HQ domain can not be upgraded to AD.  Instead, we are planning on 
creating a New seperate AD domain to be hosted in the HQ datacenter (so there 
will be one NT4.0 domain and a Win 2003 AD domain hosted from the same site).  
Slowly we will move users over to the new domain and leave their accounts 
active on the old NT 4.0 domain until the services can be replaced with 2003 
compliant applications...



  Questions:

     If I implement Exchange 2003 in the new domain, could I configure it to 
use the same domain (@globalknowledge.com) as the existing Exchange 5.5 
infrastructure?  I guess my main question is - is it possible to create trusts 
between the new AD domain with the old NT4.0 domains so that mail can be 
received by Exchange 2003 and routed to mailboxes that currently exist in the 
Exchange 5.5 setup?  Vice Versa, I would like to have any e-mails that are 
created on the exchange 5.5 mailboxes in the remote locations to be sent out 
through the new Exchange 2003 setup - until the remote domains can be brought 
in as OU's or the domain has been upgraded to 2003 AD as well.  Is this where 
the ADC comes into play?  



    I appreciate your reply and any information that would point me to an 
upgrade path similar to this.
