First have you installed the CAB files for WIN 98. On your machine. And have you regedited to have the Source files check the exact location of cab files. Copy the WIN98 file on the CD form install to file somewhere I like to use C:\windows\system... The I run a REGEDIT and go to HKEY_LOCAL_MACHINE then to software then go to micrsoft then to windows , current version,setup and source path type the location of the win 98 CAB files.
Also check your registry. If the error comes up then this is the problem.
Directions to check. Start, run, regedit, once here go to HKEY_CURRENT_USER...software\microsoft\windows\currentversion\policies\network.. check the REG_WORD
value= 0 or 1... disabled is 0....enabled is 1.
You can check the network nieghborhood then check all your properties. Mainly your client for microsoft or windows log on...If client for MS is showing the check the properties for logon validation and the box for log on to windows nt domain is selected, you can select quick logon or logon and restore network coneections. If using netware ensure the client software is installed first then reboot and check properties.
