Solution to Diagnostics Policy Service not starting

Hello,

This is a solution not a question.
It took me hundreds of manhours and I hope it helps other people.

Problem: In Windows Vista, The DPS (Diagnostics Policy Service) (in Greek: Υπηρεσία πολιτικής διαγνωστικών) does not startup either by right clicking on the network tray icon and selecting "Diagnose and Repair" (Διάγνωση και επιδιόρθωση) or by trying to start it directly from the Services panel. To get the exact error message, go to Services and try to start the service from there. This is a combination of two errors: 1079 ("The account specified for this service is different from the account specified for other services running in the same process") and 5 ("Access denied").

First error:
Error 1079 (The account specified for this service is different from the account specified for other services running in the same process).

Solution:
1. Click Start, type "Services.msc” in the Search programs and files box, and then press ENTER,
2. Locate and double click the Diagnostics Policy Service (Υπηρεσία πολιτικής διαγνωστικών) service.
3. Click the Log On tab,
4. In the This account text box, type “NT AUTHORITY\LocalService”,
5. Set both Password fields blank,
6. Click Apply and then OK

Try to start the service and you get the second error.

Second error:
Error 5 (Access denied). Cause: The service is trying to access C:\ but LOCAL SERVICE account is denied access.

Solution:
1. Right click on local drive C:\ and select Properties
2. Go to the Security Tab
3. Add LOCAL SERVICE to the user list and assign Full Control priviliges.


The DPS will start fine now and if set to automatic start mode it will never trouble you again.

Thank you for the report but that did not fixed the problem on my system. Your suggestion was helpful but there were cautions and warnings when I was using your protocol. I continued to search other forums and below is the fixed that worked for me first time out and the problem has not come back. I believe this problem happen due to a blue screen that I received after unplugging an iPhone from my locked up system. Afterwards the system ran a scan disk and I had 50 corrupt files. The on-board PC repair fixed all of them except this file. Could not get on the internet. With these two lines of code the problem is fixed. Pass it on. Thank you.


go to start ,search and type:- cmd, right click on returned cmd.exe and select "run as administrator" at the prompt type:-


net localgroup Administrators /add networkservice
press enter then type:
net localgroup Administrators /add localservice
press enter then type:
exit
press enter and restart your computer

Open services and make sure the service is started.

net localgroup Administrators /add localservice

Please note that this provides those accounts with full administrator access and therefore raises security concerns. If security is important I do not recommend this especially on servers. Those accounts should be left alone.
