Problems Caused by Setup Changing LASTDRIVE= Statement (90993)


The information in this article applies to:

  • Microsoft Windows for Workgroups 3.1
This article was previously published under Q90993

SUMMARY

Windows for Workgroups Setup changes the "LASTDRIVE=" setting in CONFIG.SYS to LASTDRIVE=Z when no other network is present, or to LASTDRIVE=P when installed with Novell NetWare as the "other" network.

If your custom network setup depends on certain drive letters always being available, the above changes may cause problems.

MORE INFORMATION

For example, if your existing LAN Manager logon script depends on being able to use certain high drive letters during the logon, and the Windows for Workgroups Setup changed "LASTDRIVE" from "W" to "P", you may receive the following errors:

  • Error 85 - local device name already in use
  • Error 15 - System cannot find drive specified
Changing the LASTDRIVE= statement does not ordinarily cause problems like this. If you are running Novell NetWare and LAN Manager, and experience drive mapping problems after installing Windows for Workgroups, try setting the LASTDRIVE statement in the CONFIG.SYS file to the previous value, which should be in CONFIG.00x.
