Indeed most problems are coming from DEP being enabled, as pointed out
before on the list:
http://seclists.org/pen-test/2005/Sep/0229.html

To fix this, just replace:
alloc(..., PAGE_READWRITE);
with:
alloc(..., PAGE_EXECUTE_READWRITE);
in the source.

In my experience, you can also run into trouble when starting PWDUMP
from inside a "SYSTEM" shell, or from a Terminal Server (or Citrix) session.

If "samdump.dll" is blocked at load time by some antivirus, you will
also experience PWDUMP becoming a "dead process" (infinite blocking on
ReadPipe()).

At the end, I would recommend using Cain (with remote Abel server on the
target). It is more stable, DEP-compatible, and not always detected by
antivirus.
