Diagnostics Policy Service won't start

I have a problem with Vista Home Premium (surprise!)

I have a connection to a home wireless network, which works: 2 computers
running XP can access it. Up until a couple of days ago mine was working too.
Now everytime I open internet explorer v.7, it won't display the webpage.
Network Diagnostics won't work because the Diagnostics Policy Service won't
start (even after trying to manually start as administrator) and I get the
msg: "Error 5: Access is denied" even though all users have full control and
read permissions.

I have also tried:
* ringing Microsoft tech support: they can't help me
* system restore: won't work or fails to complete restore
* run the repair function through bios (the computer just goes back to
startup with the same problem
* uninstall the most recent update (KB940510). Strangely, it appear in the
'update history' folder, but not in the 'installed updates' folder, so I
can't uninstall it.
* starting Windows Firewall or the DHCP client service - same problems

Any ideas short of a complete re-install of vista? I'm beginning to suspect
there's something wrong with one of the registry keys &/or system files, but
I'm not computer literate enough to know how/what to change.

Cheers

 

I'm sure there are several technical ways to address this security error,
but perhaps the best way for you is to go at it wholesale. Unless you have
spent a lot of time with Permissions so far, resetting to defaults may be a
good solution for you. My thinking is, 'It worked before, so change it
back".

HOW TO Reset Security Settings Back to the Defaults:


If this diagnostic problem is just a side issue, you may have luck with IE
pages by simply clearing the IE cache. IE, tools menu, "Delete Browsing
History"

I have a solution that worked for me!


Hopefully it will work for you!



First, try a System Restore...don't worry, it won't touch your personal
files..just the system settings.

Go to Start, Control Panel.
Type System Restore into the search box and chose the second option
under System.



It should be:

Restore System Files and Settings from a Restore Point.



Choose it and then pick a restore from before the problem started. If
that doesn't work...like if a message comes up saying System Restore
didn't complete properly, you need to try it again with a different
approach.



You may want to write these instructions down:



1. Restart your computer.
2. When it starts up again press F8 repeatedly before it hits the
loading screen.
3. Select the first option.
4. Log in as your usual user (I am unsure what the Admin pass is)
5. Select System Restore and select a date before the problem started.
~If you cannot see the system restore, move the main box out of the
way.~
6. Let is restore and hopefully the problem should be fixed.

It feels good to be telling people how to fix it! It took me 5 days to
work out the solution...and now, hopefully this solution will work for
everyone!



Oh....this is how I feel right now.....

I think I have solved the problem. Came across several postings about
this and related. Forgive me for not being more articulate with
communicating techincal terms, but I will try and keep it short. I will
check to see if it helps or anyone needs more info. First I read in a
thread posting the problem could have something to do with group policy
on my computer "Local Service" not being established. The thread, as I
remember, refered to a *"netsh command"* under the CMD prompt to
establish the "Local Service" group ( for the newby I guess, many
services belong to this group) exsisted. I found out that I received an
error because my group did. Probably good to check any way. Next, the
thread, not sure if it was the same one fore mention, (I have been
spending quit a bit of time trying to solve this problem with out
crashing my computer. So fellow newbys beware!) I ran a pre-exsisting
snap-in console *"Comexp.msc"* and checked the security settings for "my
computer". If needed I will go into more details about securty settings
for any that may need or want. But I prefer at this point you try
looking into other threads on that subject if you are that new. Started
this task because of frustration with vista. But, don't want to seem
basis about software. Since the economy is bad, freely shared info to
solve problems (whether good or bad) I think is the solution to many
problems. Thanks for this form and community! Hope this thread helps.

I had a slightly different problem; I could start Diagnostics Policy
Service, but it would stop abruptly. The course of action that I took
(which worked) was to disable the service (services.msc) and then
restart the computer. My computer restarted with internet and then I
could restart the DPS without any problem. However, this is on my
family's desktop which I installed Windows 7 RC 32 bit on. Hopefully it
will work for you.
