I like 
Roger's description of the GC in a single domain as 'single-instance 
storage'. That's a good way to think of it. One question that 
hasn't been completely addressed (although maybe implied) is what happens to 
replication if an attribute is added to the PAS in a single-domain 
environment. My guess would be that since all DCs contain the entire 
directory already, the only additional replication would bethe fact 
that the attribute should be part of the PAS and therefore available via a 
GC query. I would hope it would not cause a full replication of the 
PAS, since all the attributes are already there. True 
?

Because the 
Global Catalog data is already present in the .DIT file for the domain 
for which the server is a DC. Its in effect single instance storage - 
its not going to duplicate the data that's already 
there.

  OK, that 
  makes sense and is consistent with everything else. That actually goes 
  back to another conversation a few weeks ago when someone was asking 
  about the true advantages/disadvantages of a dedicated forest root vs. 
  single domain. The single domain would have a smaller GC (only one to 
  manage).
  
  
  
  One thing it 
  doesn't answer is why the size of the dit file doesn't change if a 
  system is not a GC. In one case, a system was temporarily made a GC 
  and then "demoted" again to just a DC. However there are other DCs 
  that were never GCs at any time. Every one of them is approximately 
  250MB (within 2 MB in either direction depending on the 
  DC).

Since you 
are one domain the sizes should be the same. The GC contains the 
partial attribute set from all domains in the forest. Since you only 
have one domain you don't have anything additional added. Also, yes 
the GC is a subset of all attributes for the domains which the DC is 
not a member. So again, since you are 

[ActiveDir] Removing sites and servers from AD

2003-03-31 Thread Mike Newell
Title: Removing sites and servers from AD





Hello,

My current setup is one domain, three sites in AD. All on their own subnet and all connected by t1's. Each site has a server in it that is a GC. The first DC and forest root server in my domain is in my location, Camarillo, and the other sites are Tustin and San Diego.

All is working well but now my company is getting rid of all the sites but Camarillo so I need to remove the Tustin and San Diego sites and servers. One of the sites, Vista, is already shut down and the server for that site is turned off and sitting in my server room here in Camarillo. 

Do I just delete the servers, then the sites or is there a specific way I need to delete these sites?

I have never done this so ANY advice is appreciated. I don't want to do this incorrectly and mess up AD in my Camarillo site.

Thank you,

Mike.




[ActiveDir] Mixed to Native and Exchange 2000

2003-03-31 Thread Myrick, Todd (NIH/CIT)
I had a beef fillet marinade in Guinness this weekend, it was actually kind
of sweet tasting.  So I recommend that or a nice piece of buffalo filet
marinade in Guinness for you AD Native Mode celebration.

We converted to Native Mode last year on many of our AD Domains.  Now is the
pain of ADCing and In-place upgrading to Exchange 2000.

Just for the record, how many of you all in-place upgraded your Exchange 5.5
Servers and org to Exchange 2000.  I am really concerned about us doing this
because we have Exchange 5.5 Servers with IS's in the 60 to 100 Gig range,
and I feel if we have a problem doing an in-place upgrade on a server, we
would have to do a disaster recovery of the server in a limited time window.
In addition it will take us some time to get all the servers upgraded to
2000, and we will have some server consolidations to contend with.  What has
everyone elses experiences been doing this?  Has in-place upgrading Exchange
5.5 servers with large IS been pretty non-eventful?

I have heard from some people are doing the following when moving from
Exchange 5.5 to 2000.

1.  Setting up the RUS first, then standing up pure Windows 2000 Exchange
2000 servers in the site, and moving the mailboxes from the Exchange 5.5
servers to the Exchange 2000 servers.  Tedious, but is easier to roll back a
failed move.  Takes forever to get to pure front-end/back-end solution.

2.  doing Inter-org migrations by creating a New Exchange 2000 org, and
migrating the accounts out of the Exchange 5.5 org into the new 2000 ORG.
Allows the New Org to start out in Native Mode, and allows for refresh of
Exchange Hardware.  Problem seems to be third-party add-ins for Exchange
like FAX Services, Blackberry, and Secure E-mail.  There are workarounds for
this though.

2003-03-31 Thread Adam Wood
 Do I just delete the servers, then the sites or is there a
 specific way I need to delete these sites?

Assuming you no longer need the servers as domain controllers:

The best thing to do make the final IT act at the site to demote the server
(transfer all FSMO roles off first if you prefer, but demotion would do that
automatically), then remove from the domain if appropriate, and delete the
site from the directory with AD Sites and Services.


If you are keeping the DC, change the site it belongs to with AD Sites and
Services, then turn it off, ship it back to Camarillo, turn it on, change IP
addressing, and pluf it in.

RE: [ActiveDir] Mixed to Native and Exchange 2000

2003-03-31 Thread Rick Kingslan
Todd,

FWIW, we did Option 1, or what is commonly referred to as the 'leap-frog'
method.  For those who don't know, the leap-frog comes from the fact that
you put in a new, pristine server, move the mailboxes to the IS, then once
box A has had all mailbox data moved off of it and all clean-up has been
done - it's scrubbed and put in place as the next 'clean, pristine' server
for the next mailbox move.  The porcess continues until you're completed -
leaving you with one extra box (usually to be the new box in your Exchange
front or back end).

Good luck!

  installed applications / services (dhcp, wins, lprserver).it is 
  also intended to change the domain membership of these DC's in thesame 
  process. the observed behaviour is that the Windows 2000 setup 
  routinedetects its configuration as a DC and generates a "red" warning in 
  a systemcompatibility report stating that the PDC should be upgraded 
  first.presumably the setup routine must do some sort of query against 
  the PDC todetermine its OS version ??the domain from which these 
  DC's are intended to be migrated is in fact aNT4 domain, and this seems to 
  be critical to the continuance of the setuproutine.is it correct 
  that there is no option for the existing domain membership tobe modified 
  in this setup routine ??it seemed to me that the dcpromo routine that 
  initiates at first logon whenWindows 2000 starts would be flexible enough 
  that if the administrator sodecided to remove any exsiting security 
  information from the original NT4domain and replace it with the 
  information from an administrator specifieddomain ??if this is the 
  case then the available options (given that the upgrade ofthe PDC to a 
  production domain is by far the least preferable) need to 
  beevaluated;is it a "supported" operation to take the BDC offline 
  from the network,promote it to PDC (merely to allow the setup routine to 
  proceed) whichpresumably would complete given that the system would not 
  detect any - thisbegs the question as to the checks that a BDC promotion 
  goes through tocomplete - is it merely the non-detection of an exsiting 
  PDC or is there abit more sophistication ??from here then once the 
  system is running Windows 2000, the dcpromo processcan be stopped, and 
  reinitiated once the computer is joined to the networkonce again as a 
  Windows 2000 member server, and joined to a new domain ?otheriwse it 
  seems to me that the only way of proceeding is to use the"clean 
  installation" method and reinstall all applications / services.on this 
  tack, it seems to me potential issues with the restore of a DHCPserver 
  configuration (backed up by taking a copy of the relevant NT4registry key) 
  to a Windows 2000 DHCP server - is this a supported operation.I will 
  be very appreciative of input from the newsgroup on this 
  oneGT
