Greetings All...(as you can detect, I am new here, and have attempted to read/follow the instructions. I am limited as my issue involves my inability to connect my pc to the internet.)

Moderators: Could you please move this topic to appropriate area, or please advise what I should do to gain assistance? Thanks!

On yesterday, I read a blog from Prevx regarding the "black screen" that is happening with a lot of Windows 7 and Vista users after running updates, etc (I run Vista). I thought this may have been my problem, as I have a 1.5 yr old monitor that just blacks out at will. I attempted to download the fix, directly from the blogsite, Prevx Black Screen Fix Blog and from that point, lost my internet connection (wireless), and could not reconnect.

The fix was an executible file, "fixshell.exe" with additional instructions to run "http://info.prevx.com/download.asp?GRAB=BLACKSCREENFIX", after download through the Task Manager. By the time I clicked on the download, the internet connection was lost. I called the support desk for Belkin (the wireless router) and LinkSys (the wireless adapter), and both said their components were operating fine after a few instructions.

When I hover over the network icon in the system tray I recieve this message: "The dependency service or group failed to start". I am also unable to do a Restore as all the Restore Dates have been wiped out.

When I click on the network icon to 'diagnose and repair', I receive this message: "Could not start diagnostic policy service on local computer. Error 5: Access denied." I get this also when I attempt to manually start the Diagnostic Policy Service.

I ran RegistryPatrol last night, and attempted to change the parameters of the DPS by creating a "Trusted Installer" user; all to no avail.

I unplugged the wireless connectivity and plugged the internet cable directly to my cpu; again, to no avail. No internet access. I am now getting this error message when I attempt to 'diagnose and repair': "Error 1114: A DLL Initialization routine failed".

A relative advised me to come here, download ComboFix and run it. I have since read that you do not recommend that, and though I've ran it, from a cd, nothing happened to fix or repair my issue.

I truly hope that someone is familiar with this issue and can assist me. I work from home, and this is causing me much anguish.

Thanks Figgis and Garmanma, but these options did not work, and I did not have the Proxy settings checked. I have attempted to run the programs to place a topic in the HijackThis forum. I appreciate your assistance.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/276179/diagnostic-policy-service-access-denied/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days, up to two weeks perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :huh:
