Hi kalani,
Yes, you are correct, Vista is in, what is called a 'Mod-Auth' Tamper state. There are 2 types of Mod-Auth tampers.
1) A critical system file was modified on disk - What this means is that the file, located on the hard drive, was modified in some way.
2) A critical system file was modified in memory - What this means is the file itself (on the hard drive) is un-modified, but the code, from that file, running in the system, was modified in some way.
Because of the Mismatched files listed under the "File Scan Data-->" line of your Diagnostic Report, I beleive your issue is caused by: 1) A critical system file was modified on disk
Number 2 is usually caused by a running program that is incompatible with Vista.
Number 1 can be caused by a malicious program (spyware, malware, virus) or by manual file modification (by a user of the system). There is also a very small chance that an Update may fail in mid-update and cause this type of issue. As a safety mechanism, Updates are made so that if they fail, they roll back any updating that was done before the failure, but there is an off chance that the roll back did not occure.
So, what I would like to do is exclude a failed update as the cause of your issue. To do that, I would like you to uninstall/reinstall the update that correspond with mismatched critical system files seen in your Diagnostic Report under the "File Scan Data-->" line. (i.e. rpcrt4.dll[6.0.6000.16525]) by following the below steps:
First, uninstall the updates:
(The below steps assume Vista is currently in reduced functionality)
1) Log in to Vista and select the options that brings up the Internet Browser
2) Type: %windir%\system32\control.exe
3) You may be asked if you want to Save or Run, select Run
4) Control Panel will open
5) Double click the ‘Programs and Features’ icon (in XP it was called the ‘Add/Remove Programs’)
6) In the upper left hand corner of the window (right under ‘Tasks’) click the “View installed updates” link
7) Now look for and select KB933729
8) Click ‘Uninstall’
9) Reboot
Now, reinstall the updates:
(At this point, Vista may or may not be in reduced functionality, the below steps assume that Vista is in reduced functionality)
10) Log in to Vista and select the options that brings up the Internet Browser.
11) Go to http://www.microsoft.com/downloads
12) Search for KB933729
13) In the search results, click the Vista version of the update that has KB925902 in the name.
14) Click the 'Download' button.
15) You will be given the choice to Save or Run, select Run
16) Reboot
Please post back on if this does or does not resolve your issue.
Thank you,
