Find a friend/neighbor/et cetera with a retail Windows Vista DVD, insert it, restart your computer, and press any key to boot from CD/DVD when prompted. (You may have to edit your BIOS settings to set your optical drive as your primary boot device.) Once the Windows Vista installer launches, proceed through the keyboard/language selection and, instead of clicking Install Now, choose "Repair my Computer" from the bottom left corner.
From there you can try two things:
1.) Running System Restore, reverting to a time prior to when the problems began.
2.) Using the command line to repair Windows file corruption.
If neither work, and you have no other admin accounts (and cannot create them now), you may be better off backing up your personal files and reinstalling from the Dell DVD given the unavailability of the command prompt and various admin controls.
P.S. PSTScan.exe is only for repairing Outlook files.
P.P.S. You will normally see multiple instances of Rundll32, one for SYSTEM and one for every user currently logged in.
My system: Dell Latitude D820. 32 bit OS Vista SP1
My problems (in no particular order):
#1) I cannot access my Guest account, my normal account is not acting like it should (I am denied access frequently even though I am the administrator)and my attempts to correct this via PSTScan fails:
Product Microsoft Personal Folders Scan/Repair Utility
Problem Stopped responding and was closed
Date 6/21/2009 6:42 AM
A problem caused this program (PSTscan.exe) to stop interacting with Windows.
#2) Product Windows host process (Rundll32) Stopped working. But in the Task Manager I see three version of the same running. Should I have 3 version of this running?
#3)I can't use the command line (Service not accepting control messages at this time)to perform any repair that has been recommended in forums. Nor can I access the Manage User Accounts tool to rebuild the user profiles. Nor can I access the EventViewer (Service not accepting control messages). I can't delete files from the common folder (Roxio-I get that pesky compatibility error message even though I deleted the application there are Roxio drivers and files still in the common folder- I found the thread about the patch from Roxio, but could not open the downloaded file as I need permission and am denied)
#4) Sound is off. Video runs slow and choppy. This started 2 days ago.
I have scanned with Norton. I see no virus from Norton. I tried to scan with Pandascan 2.0 but could not get permission to run the ActiveX add-on. In fact I cannot access any downloads. The irony is that all this seems to have started after both Norton and Microsoft tried to run automatic updates at the same time. (Monday June 15)
Other error messages i have been getting lately but not regularly:
APPMOBDEV stopped working
DCOM terminated unexpectedly
Internal Network Power Card Management stopped working
This is all way beyond my IT skills. I would appreciate any help anyone has to offer. Thank you.
By the way I was also unable to use the command line to regedit from the Safe Mode as well (Service not accepting control messages at this time). All misbehaviors are found in Safe Mode as well as Normal mode. There was a time (6/17) that I could not log on except via Safe mode, but that seems to have been a brief interlude of nonsense.
