Hi! Everybody, While installing Exchange server in Windows 2000 server DC, it was unable to install "Exchange Messaging and Collaboration Services" with following error: Setup failed while Configuring X400 address type for i386 processor (error 0xC0070000: The operation completed successfully.) . Additional information: The operation completed successfully. Facility: Win32 ID no: c0070000 Microsoft Exchange Setup mode = 'Install' (61953) Setup encountered an error during Microsoft Exchange Messaging and Collaboration Services of Install component task. Everything else went fine but now there is no default storage group in my server. Can anyone help me with the problem I'm having. Ron --------------------------------- Do You Yahoo!?
