Microsoft Mail Postoffice Icon Is Not Displayed After Windows 2000 Server Upgrade

After you upgrade to Windows 2000 Server from Microsoft Windows NT 4.0 Server, the Microsoft Mail Postoffice icon is not displayed in Control Panel and you cannot administer a workgroup postoffice or create a new workgroup postoffice.

This behavior occurs because two files that are required for Microsoft Mail Postoffice are not included on the Windows 2000 Server CD-ROM.

To resolve this issue:

1. Obtain the following files from the I386 folder on the Windows NT Server 4.0 CD-ROM:
   Wgpoadmn.dl_
   Wgpocpl.cp_
2. Expand the files to the Winnt\System32 folder on your Windows 2000 installation.

Microsoft has confirmed this to be a problem in Microsoft Windows 2000.

Microsoft Mail Postoffice is not Year 2000-compliant.
