IE5DOMSetup.cpp
|
|
|
|
Abstract:
|
|
|
|
This DLL fixes a problem with Internet Explorer's IE5DOM.EXE package. If
|
|
the command line contains /n:v, the package will replace the 128-bit
|
|
encryption modules that shipped with Win2K, which can cause serious harm -
|
|
no one can log on to the machine.
|
|
|
|
This shim simply removes /n:v from the command line so that the package
|
|
does not replace the encryption DLLs.
