XADM: Service Packs Fail to Install All Files with -d Option

• Microsoft Exchange Server, version 4.0
• Microsoft Exchange MS-DOS client, version 4.0
• Microsoft Exchange Windows 3.x client, version 4.0
• Microsoft Exchange Windows NT client, version 4.0
• Microsoft Exchange Windows 95 client, version 4.0
• Microsoft Schedule+, version 7.0

SYMPTOMS

After you expand files for Microsoft Exchange Service Packs using the PKUNZIP -d option, some of the files and/or directories are missing.

CAUSE

It appears that PKUNZIP has a limitation of seven directory levels. For example the SP2_400I.EXE file, when expanded, is four levels deep. If you start expanding this file in a directory that is greater than three levels deep, it will fail to expand any files that are in a directory that is eight levels deep, and it will fail to create directories at the ninth level.

WORKAROUND

There are two solutions to this issue:

• Make sure you do not decompress the Service Pack 2 files in a directory that is deeper than 3 levels.

1. Use the MS-DOS Substitute command to map a drive to the directory structure. For example:

         SUBST E: C:\SERVIC~1\EXCHAN~1\SERVIC~1\Server
   

2. Decompress the SP2 files from drive E.

MORE INFORMATION

The level of directory that this problem will encounter will vary depending on the length the directory path. If using the substitute command, remember this is an MS-DOS command, and it does not support long file names.
