Help Please.. I tried to add a new receive connector and received this message, but my internet searches did not give anything helpful. I read a bit about how a SP has modified the AD, but am unsure how to rectify it. Summary: 1 item(s). 0 succeeded, 1 failed.

What about when you create receive connector thru EMC ?, Also type cmdlet which generate when you complete EMC wizard. Anil

Hi Greg, What's the service pack and rollup you installed? Exchange 2007 SP3 with Rollup 1? Do you remember when the issue started happening? After the RU1 installation? If yes, please run the setup /ps from the SP3 disc.

Yes, thanks for the updates. Thanks Anil, but I was using EMC. Many thanks to Frank, I went with your suggestion to try the setup option, but it complained about a reboot pending, so I have just completed that and now it is complaining about my old exchange 2003 server not being present. So I was just researching this situation. I had removed the old server some months ago, and removed all reminisces of that DC and thought it was good.. I still have the server untouched, but it is quite old now.. I was also trying to look for that reference in ADSIedit, and I know that is fraught with danger, but I'm getting desperate. There appears to be no 'search' functionality with it either, I suppose this would be considered dangerous, any ideas? the error is below: Welcome to Microsoft Exchange Server 2007 Unattended Setup Preparing Exchange Setup No server roles will be installed Performing Microsoft Exchange Server Prerequisite Check Organization Checks .........................

The Exchange Server Setup operation did not complete. For more information, visit http://support.microsoft.com and enter the Error ID. Exchange Server setup encountered an error. Thanks again. P.S. Just found an old server entry in ADSI under: configuration/services/Microsoft Exchange/<domain>/Connections Maybe it is time to migrate to the new domain, a .local which is something I always wanted since taking on this role, I was hoping that the exchange wasn't going to be the product that dictates that move though.

Hi Grey, About the error message "Unable to retrieve the schema master server object from Active Directory", seems like the setup can't locate the Schema Master. Can you run Netdom /query fsmo? And how about open Active Directory Schema in the MMC? You may need to register schema first: run regsvr32 schmmgmt.dllPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Thanks Frank, I get this with netdom: C:\Program Files\Support Tools>netdom QUERY FSMO The system cannot find the file specified. The command failed to complete successfully. But with the gui, It connects to the Primary DC Greg Cost

ok, netdiag /v gave me some entries from the old server under the Netbios Remote Cache Table. just trying to work out how to get rid of them.Greg Cost

ok, cleared out now, but awaiting a reboot to retry. Greg Cost
