Error running connection agreement wizard during Exchange 5.5 to 2003 migration

The error below is reported when I run AD connector Services - ADC Tools -

Step 3 (resource mailbox wizard) : There are no Resource Mailboxes to configure.

Step 4 (connection agreement wizard) : Error: The organization o=First Organization is already installed into this forest but the configured 5.5 server is a member of organization o=hd. Please choose a 5.5 server in the correct Org.

Both Servers are backup domain controllers, the 5.5 machine is running NT4, both Servers are listed in the AD DC section of AD users and computers.

Any suggestions?

the entires of the old install are still present in the AD and will not allow the ADC configuration to proceed.

These entries need to be removed. have you configured any ADC agreement till now like RCA or PFCA?

if not then you can delete this entry CN=Microsoft Exchange

once done, you need to replicate the domain controllers and after that forestprep and domainprep needs to be run again

PLEASE TAKE SYSTEM STATE BACKUP OF ACTIVE DIRECTORY BEFORE MAKING ANY CHANGES VIA ADSIEDIT.MSC

No, I was under the impression that I had to go through the steps including the Connection Agreement Wiz before installing Ex2003, is this incorrect

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

 
rakeshmiglaniCommented:
that is correct. exchange 2003 has to be installed only after the ADC has been run and configured.

check via adsiedit.msc whether exchange ORG is present in AD

you need to check in the configuration container and then expand services and then microsoft exchange

let me know what you have there

two entries -

cn = active directory connections

cn = first organisation (this can be expaneded, and shows as follows)

cn = address list contained
cn = administrative groups etc. etc.

> cn = first organisation (this can be expaneded, and shows as follows)

this means that exchange 2003 is already installed

try to open exchange system manager and see what comes up. and also expand the cn=administrtive groups and then go down till you see the servers container. check what server is listed there

I've just noticed that their are two ADC's listed :

HDMail - older upgrade server that no longer exists

HDMailServer - the one I'm working on

Unfortunately the connection agreements have been made with the first on HDMail which as I said has been formatted quite some time ago.

Can you suggest how I reverse these agreeement and ensure that they're made with the correct Server?

where are you checking these connection agreements from? adsieidt.msc? if yes then how many do you have there?

spower22Author Commented:
msexchange - active directory connector services : looks like this

Active Directory Connector (HDMail) has agreements listed in right hand pane

Active Directory Connector (HDMailServer) no agreements listed

Can't see any reference to HDMail in ADSI edit

ok, so that means that the connection agreements had already been created. check whether you have any server by the name of HDMAIL in your network. if you find it then check whether it has ADC installed.

if it is not present in the domain that it means that it does not exist and these connections are orphan. so we need to check whether these agreements did any changes on the exchange 5.5 side.
to check that you need to open the exchange 5.5 administrator in raw mode (admin.exe /r)
then highlight any mailbox in the global address list and then click on the file menu. you have an option there about raw properties.
open that and check whether any ADC-global-names attributes are stamped.
do this activity on random users and DLs to check

The Server HDMail is still listed as a backup server but is no longer present on the domain, it had ADC installed.

I've checked the attributes in raw mode and can't see any ADC global name attributes but i'm not sure what to look out for...

if there are no adcglobalnames attributes listed then that means that the ADC did not stamp the users in exchange 5.5

i wanted to check whether ADC stamped the exchange 5.5 users when it was installed earlier. but it appears that it has not stamped. so now it is safe to delete the Microsoft Exchange container via adsiedit.msc and then start again by running forestprep and then domainprep.
once you run forestprep it will ask for your the name of your exchange 5.5 server which you have to provide at that time.
once this is done, install the ADC and then try to configure via ADC tools and it will work this time.
as mentioned earlier take a system state backup of the active directory before making any changes

I have already removed the exchange container, and re-run sys and forest prep, i then installed the adc and ran the adc, as per my earlier post (see copy below) this has resulted in the agreements being made with a server that no longer exists.  There is no longer a reference to exchange in the config. section of adsi edit.

If i go to the properties of the active directory connetor service - for either users or public folder there is an option to 'Select the Server t orun the connection agreement' the drop down menu offers both the hdmail and hdmailserver servers, if can i change the association there?  

msexchange - active directory connector services : looks like this

Active Directory Connector (HDMail) has agreements listed in right hand pane

Active Directory Connector (HDMailServer) no agreements listed

Can't see any reference to HDMail in ADSI edit
