I've received error message saysing that my system32 is missing a module. I
was wondering if i could re-install the module. I do not have the cd's from
which to re-install the file. I don't know if I could install this file from
somewhere on Microsoft.com, I have looked but as of yet cannot find anything.

The full error message is

NTVDM KERNEL: Missing 16-bit system module
Please re-install the following module to your system32 directory: GDI.EXE
