Hi,

I tested existing exploits for PnP bug on my W2k SP4 machine (Spanish)
and they didn't work ("services" process is crashing but I got no
shell). So I did a quick review with Olly and I realized that
umpnpmgr.dll is being loaded at a different base address. In Spanish
systems this base address is 0x76770000 but current exploits are
assumming (I guess) 0x767a0000. Then I did a quick hack to HOD's exploit
and it worked perfectly. I also modified Metasploit's module and
included a target for Spanish systems. I've attached resulting exploits
(they are trivial, though).

Is it usual that Windows DLLs have different base address across same
Windows/SP versions (but different languages)?
