The following is based on what happened on 19th May 2009:
When windows XP starts up, I get a message from the DEP saying "To help protect ...." and the process being shut down is "Generic Host Process for Win32 services".
Some time later (about 1 minute), I get a bubble saying “Your computer might be at risk because you have no firewall set” – which is nonsense, because it is set.
I then immediately receive a message saying "Generic Host Process for Win32 services encountered a problem and needed to close". The date/time stamp on this message is 18/05/2009 08:55:56 (nearly one day earlier !). There is an option to send an error report and I have sent it numerous times (this incident occurs nearly every day).
Then I get both messages again, but now the date/time stamp reads 19/05/2009 07:24:51 (which is correct).
No idea why or how – is that part of the problem? I do know that XP seems to think that I have two instances of itself loaded on my PC, because I get the operating system options coming up during the boot sequence, showing XP twice. The original XP install failed for some reason that I cannot now recall, so I re-installed, choosing to overwrite the existing copy.
After these messages, I can use the PC normally, but I am concerned about this DEP message. So I would really appreciate some help in sorting this. My system is fully patched, btw, and I have screenshots of the messages that I can send to anyone who can help.
