Hi All - First my apologies I am not a driver developer, but I hope some of
the experts on this group can help!
I have an XP machine on which the Microsoft userdump utility fails to
install. The problem appears to relate to userdump.sys, installed as a
legacy kernel mode driver. This will not start, and on boot-up or attempting
to start (via the service userdump.exe which depends on it) SCM logs "The
system cannot find the device specified". sc query udmpdrvr shows it stopped
with WIN32_EXIT_CODE 20, which I think means the same. During an attempt to
start it, Regmon shows an enum\root subkey LEGACY_UDMPDRVR being created by
Services.exe, but it is then promptly deleted again.
Can anyone please suggest ways of troubleshooting this issue, or suggest
what might be going wrong?
Thanks in advance - Mike.
