Win 98SE Startup Problems after attempting to install Picture It via net map dr

I used my server's shared CD-Rom drive to install Picture
It! Publishing Platium v.2002 to 30 Windows 98SE
computers. At each Win98SE computer, I mapped to this
shared drive and started the install of Picture It. After
about 45 minutes, Picture It seemed to stop responding, so
I canceled the install on all computers. After restarting
these 98SE computers the Win 98 operation system no longer
loads. These computers load to the point of asking for
the network logon password, accepts the password and then
I get a blank green screen - no icons, taskbar, etc. Any
idea how I can correct this problem?
