SYMPTOMS
A Windows NT server acting as a centralized backup server is unable to back up a Microsoft Exchange mail server in the Microsoft Exchange mail database (Information Store and Directory) format if the server is not a Microsoft Exchange mail server. This occurs using either the current Windows NT backup utility or Arcada's NTBackup software.



CAUSE
A Windows NT Server that is not running as a Microsoft Exchange mail server does not have the three required DLL files that are new in Microsoft Exchange Mail Server and the current NTBackup.exe cannot use these new DLLs.

Currently, NT Backup has no capability to distinguish a Microsoft Exchange mail server from other computers and so cannot back up a Microsoft Exchange mail server's files in the Microsoft Exchange Mail Server Database (Information Store and Directory) format.



RESOLUTION
To allow NT Backup to recognize and back up Microsoft Exchange mail servers, close any opened backup window and do one of the following:

 If you are copying files from an existing Exchange RC1 Mail Server:  Rename or delete the current WINNT-WINNT-ROOT\SYSTEM32\NTBACKUP.EXE from the NT Backup Server. Copy Winnt-Winnt-Root\System32\NTBackup.exe, Edbbcli.dll, and Msvcrt40.dll from a Microsoft Exchange mail server to the Winnt- Root\System32 subdirectory of the Windows NT backup server. Copy Exchsrvr\Bin\Edbback.dll from the Microsoft Exchange mail server to the Winnt-Root\System32 subdirectory of the Windows NT backup server.

-or-

 If you are copying files from Exchange RC1 Mail Server CD-ROM:  Rename or delete the current Winnt-Winnt-Root\System32\NTBackup.exe of the Windows NT backup Server.</li> Copy NTBackup.exe, Edbbcli.dll, Edbback.dll and Msvcrt40.dll files in Setup\I386 (or MIPS or Alpha) on the Exchange Mail Server CD-ROM to the Winnt-Root\System32 subdirectory of the Windows NT backup server.</li></ol> </li></ul>
