SYMPTOMS
When you try to use Netsetup.exe to perform a server-based setup ofWindows 95 on a system running Microsoft Workgroup Add-On for MS-DOS,you receive the following error:
Application Error "SUWIN caused an illegal instruction in module GDI.EXE at 0001:16EF."
NOTE: This error can also occur on systems with insufficient hard diskspace to create a temporary setup directory.
CAUSE
This error occurs on Workgroup Add-On for MS-DOS systems configured to usethe basic network redirector. When Windows 95 is set up from an MS-DOSprompt, it loads a mini-version of Windows. This version is very sensitiveto system files not being accessible or loadable. The basic redirectorincluded with Workgroup Add-On for MS-DOS may occasionally drop filehandles and/or network connections. After this occurs, the mini-version ofWindows fails to load code segments or resources and generates the errormessage.
RESOLUTION
Run Setup after starting Workgroup Add-On for MS-DOS using the fullredirector. To start Workgroup Add-On for MS-DOS with the full redirector,type "net stop" (without the quotation marks) at an MS-DOS prompt and logoff the system. Then type "net start full" (without the quotation marks)and log on to the system. Setup should now run without generating the errormessage.
