WFWG Err Msg with DblSpace: PRO0003E: PROTOCOL.INI File Open (93652)

The information in this article applies to:
    Microsoft MS-DOS operating system 6.0
    Microsoft MS-DOS operating system 6.2
    Microsoft MS-DOS operating system 6.22
    Microsoft Windows for Workgroups 3.1

This article was previously published under Q93652
This information applies to both Microsoft DoubleSpace and Microsoft DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames.


If Windows for Workgroups is installed on a DoubleSpace-compressed drive, you may receive one of the following error messages or the system may stop responding ("hang") when the network drivers are loading:
    PRO0003E: PROTOCOL.INI file open failure
    Unable to open Protocol Manager
    Error 3653: The protocol manager could not be found


These errors occurs because Windows for Workgroups cannot find the path to the PROTOCOL.INI file in memory.


To work around this problem, make sure that the DEVICEHIGH command for DoubleSpace is located before the DEVICE command for PROTMAN.DOS in the CONFIG.SYS file. For example:
   devicehigh=c:\dos\dblspace.sys /move
   device=c:\windows\protman.dos /i:c:\windows
