I tried to run the command to allow anonymous SMTP senders and I am getting this error. Is this because I originally had an Exchange 2003 server feeding the 2007 server? I don't know where the reference is to the old server nor how to remove it. Any help would be most appreciated. Thanks [MSH] C:\Documents and Settings\Administrator>Set-ReceiveConnector -Identity "Default <ServerName>" -PermissionGroups "AnonymousUsers"Set-ReceiveConnector : The operation could not be performed because 'Default <ServerName>' could not be found on SERVER.XXX.com.At line:1 char:21+ Set-ReceiveConnector <<<< -Identity "Default <ServerName>" -PermissionGroups"AnonymousUsers"[MSH] C:\Documents and Settings\Administrator>

most likely still in active directory - use ADSI Edit to remove it. see kb833396
