There is a dependency in certain modules (notably php_openssl) on apphelp.dll. This file seems to only be available on WindowsXP (and the file shipped with XP won't work on win2000). If I am correct (I'm not entirely sure), any use of this dll will render the extensions useless on any windows version prior to XP).

Source: DLL Help on MSDN. (The file is only listed as part of Windows XP).

there's no dll in the binary package which is directly dependent upon that 
dll. where did you get that info from?

It seems that I have narrowed down the problem. The culprit does seem to
be IE6. I did the same installation on a Win2000 machine with IE5.5
instead on IE6, and the install came clean, including the dependencies.

IE6 seems to put in a dependency on a file which belongs to XP; why it
doesn't break other apps is a mystery, but that's M$.

I'm definitely paying the price for not following my own advice about
putting a new version of a microsoft product on my system before the 2nd SP.

Report this to Microsoft.  Not a PHP bug -> bogus.

I found a number of EXEs and DLLs that Dependancy Walker show as requiring the missing APPHELP.DLL. As a bit of humor, open DEPENDS.EXE in Windows 2000 with IE 6; you will find some flagged DLLs that can't find APPHELP.DLL

Thanks for having this site accessable; it helped track down the same problem in one of our products also.

build a bogus apphelp.dll

borland c++ source
---BEGIN APPHELP.C---
#include <windows.h> 

__declspec(dllexport) BOOL ApphelpCheckShellObject(
  REFCLSID ObjectCLSID,
  BOOL bShimIfNecessary,
  ULONGLONG* pullFlags
)
{
    return FALSE;
}
---END FILE---
then build it with 
bcc32 -WD apphelp.c
copy it in a path directory
it work on windows 2000 no problem so far with this fix.
msdn has been quite usefull to know what this function basically do.

The fix identified here disables Windows Explorer and other features under Win2K after the first reboot.  I do appreciate the openess of the site, it has been very helpful.
