Dear All,I have configured the additional domain controller and installed the Exchange 2007 SP1. The storage Group Name is Default i.e: First Storage Group and I tired the below command on management shell but it show the below problem. Appreciate your help on the same.Enable-StorageGroupCopy -Identity First Storage Group -StandbyMachineserver1.example.com -ReplayLagTime 0.1:0:0Error Message: Enable-StorageGroupCopy : The operation could not be performed because object ' First Storage Group' could not be found on domain controller 'server1.example.com

Please describe the current exchange topology. Do you install the exchange on the DC? When did you add the second DC? Please wait 48 hours for the AD replication, a replication lag can cause such issue Please use quotation mark to enclose the first storage group since therere space among the name of the storage group

I have single Exchagne server in DC and I have another server which is additional domain contrller and it is in DR 10 KM far from DC which is connected through the Fiber link. In the DR server I installed Exchange 2007SP1 and try to configure the SCR on the DR server but get the above posted problem.

Please run Repadmin /showrepl and Dcdiag /v on both DCs to check the AD replication Verify replication with other domain controllers By the way, For security and performance reasons, we recommend that you install Exchange 2007 only on member servers, and not on Active Directory directory servers (Reference)

Yes,I tested all the things and replcation is done it. But still the problem is same. Is it because of the Default name of storage group?Shall I need to change it named sg1? and is there any problem will occour if I change the SG name?

Per my knowledge, theres no problem to rename the storage group Set-StorageGroup -Identity "Exchange-Server-1.Contoso.com\StorageGroup-1" -Name MyStorageGroup Renaming the default storage group / mailbox database or deleting and recreating

Dear All,I still have the same problem for standby replication. I could not configure the SCR. Problem is still the same:Enable-StorageGroupCopy -Identity First Storage Group -StandbyMachineserver1.example.com -ReplayLagTime 0.1:0:0Error Message: Enable-StorageGroupCopy : The operation could not be performed because object ' First Storage Group' could not be found on domain controller 'server1.example.comAnyone suggest the same.thanks on advance.

dear arun , Before you can create a new storage group that is enabled for SCR, you must first make sure that the paths for the storage group files, log files, and database file can be identically matched on the SCR source and all SCR target computers.have you verified that also . 1)check whther active directory replication service is working fine .2)Test-ReplicationHealth power shell commands.3) Evaulate the Events logs at your end .4) try out this command get-StorageGroupCopyStatus -Identity Cmsname\First Storage Group -StandbyMachineserver1.example.com | flhttp://technet.microsoft.com/en-us/library/bb687965.aspxThanks .SAsyed.arsalan
