Linking AD and Exchange to Existing DC - 15.Oct.2007 5:52:02 AM

I've just installed an SBS 2003 server on my network. It is a domain controller, runs all the FSMO roles, has AD and Exchange setup etc.

There is an existing DC on my domain that this SBS 2003 Server will eventually make obsolete. For the moment however I'm running them both in conjunction with each other.

My problem is getting exchange to work on the new server correctly. AD is replicating across from one to the other instantaneously, and I can transfer mailboxes from 1 server to the other, but mailboxes on the new SBS server cannot send outgoing mail externally, or even to mailboxes on the other server. They can recieve incoming mail from my domain and from outside my domain alright, but can't send anything out.

As well as this they cannot download the address book. It doesn't seem to be replication to the new server, and when a mailbox on the new server recieves a mail from a mailbox on the old server its properties display as if its an external mailbox (properties show name and smtp address only, not address book details as it should)

I'm very new to exchange, especially this type of setup detail. Can anyone help?

thanks,

Jody

pls run exbpa tool (www.exbpa.com)

what is the NDR you are getting when you are trying to send mail to second server or internal user or external user.

I've downloaded that software and rang it thanks, not sure what its telling me though..I'm fairly new to this side of exchange.

The NDR at first just informs the user that there is a delay in sending the message.

"This is an automatically generated Delivery Status Notification.

THIS IS A WARNING MESSAGE ONLY.

YOU DO NOT NEED TO RESEND YOUR MESSAGE.

Delivery to the following recipients has been delayed."


Then after a long period you get 
"Could not deliver the message in the time limit specified.  Please retry or contact your administrator."

Like I say, incoming mails from external accounts, and from internal accounts are fine.

When I try to send an email to an external address from a mailbox on the new server I get this
           "There was a SMTP communication problem with the recipient's email server.  Please contact your system administrator.
           <server.domain.com #5.5.0 smtp;550 <external@domain.com> Relaying denied>"

hi,

If you can't telnet, you need to check is there any firewall policy or antivirus is blocking  and smarthost can also be part of problem

Open Exchange Manager,Exchange server name, Protocols, SMTP, SMTP Virtual Server Properties, Access and check settings for Connection and Relay.

Connection "only allows the list below" and the list is both my servers

Relay is the same, but also had the button ticked to allow all computers that successfully authenticate to relay, regardless of the above list

Both servers have the same settings

I thought it was not possible to add additional domain controllers using SBS on to a new server!
Is the new server have a completely different domain or using the same domain as before?
Is Exchange set up with different email domains or the same email domain? If the same then it might be impossible for mail to transfer to each other unless all mail is moved to one server.
Where are MX records pointing to? Old or new servers?

Hi, I added SBS to the existing domain using instructions from a Microsoft Whitepaper. All FSMO roles have been moved to the SBS server, but the old server is still running AD and Exhange. I don't think there should be a problem with that.
Exchange is setup with the same email domain also. Why would that be impossible?
I'm not sure what you mean by the MX records?

Can you check the following?
1. Can you resolve server names from each server using nslookup?
2. Can you telnet on port 25 to each server from the other server to test smtp?
3. Have you run netdiag, dcdiag and possible smtpdiag tools?
4. Have you tried the Exchange Analyzer tool to check configuration?

Hi.
1. I seem to be able to resolve server names from each other through nslookup.
2. I telneted to the old server form the new server, went through some of the commands to test smtp, but my telnet skills let me down when entering data. I cannot telnet to the new server from teh old server. I'm getting a connection failed on port 25 error
3. I get the following errors from DCDiag.exe
      - There are warning or error events within the last 24 hours after the SYSVOL has been shared. Failing SYSVOL replication problems may cause group policy problems
      - ISMserv Service is stopped on newserver....newserver failed test services
      - Unable to connect to NETLOGON share! (\\newserver\netlogon). [newserver] An net use or LsaPolicy operation  failed with error 1203. Win32 error 1203.....newserver failed test NetLogons
      - Warning: DsGetDcName returned information for \\oldserver.domain.com, when we were  trying to reach newserver. Server is not responding or it is not considered suitable.....newserver failed test Advertising

I don't have any other diag tools at the moment. I'll try to find some. Can't find netdiag even.

4. I downloaded and installed the best practices analyser tool, but it doesn't seem to be giving me related errors. There are a list of things it wants me to do, and one of them is about offline address books...another issue I need to resolve...but there doesn't seem to be connection problems.

thanks

Since Exchange is linked to Active Directory, I suggest that you sort out your Domain Controller problems first.

1. On your DC run NET SHARE and you should get these shares at least:
C$, Admin$, IPC$, NETLOGON and SYSVOL.

C:\WINDOWS\SYSVOL\sysvol should be shared as SYSVOL.
C:\WINDOWS\SYSVOL\sysvol\mydomain.com\scripts should be shared as Netlogon.

The Netlogon and File Replication Service looks after these. You need to enable those shares for the DC to work properly, esp for Group Policies and login scripts:

KB315457 - How to rebuild the SYSVOL tree and its content in a domain
KB312862 - Recovering missing FRS objects and FRS attributes

I have setup the shares as below. They were not setup on the new server. I am hoping I don't have to go through the process of rebuilding the SYSVOL. The procedure scared the bejesus out of me.
I've also forced replication to the new server.
Not sure it's made a difference though.
