Warning: This post could be an interesting reading material only if you have windows system-files corruptions and as a real alternative to the expert exchange conspiracy ;)
This small vista saga started when I found myself unable to access domain assets (exchange, domain servers, shared storage etc.)
Browsing quickly throughout Event Viewer System logs I found out that Workstation, Netlogon and Computer Browser services were down due to rather long and frustrating service dependencies failures:
- The Netlogon service depends on the Workstation service which failed to start because of the following error: The dependency service or group failed to start. (Event ID 7001)
- The Computer Browser service depends on the Workstation service which failed to start because of the following error: The dependency service or group failed to start. (Event ID 7001)
- The Workstation service depends on the SMB 2.0 MiniRedirector service which failed to start because of the following error: The dependency service or group failed to start. (Event ID 7001)
- The SMB 2.0 MiniRedirector service depends on the SMB MiniRedirector Wrapper and Engine service which failed to start because of the following error: The dependency service or group failed to start. (Event ID 7001)
- The SMB 1.x MiniRedirector service depends on the SMB MiniRedirector Wrapper and Engine service which failed to start because of the following error: The dependency service or group failed to start. (Event ID 7001)
- The SMB MiniRedirector Wrapper and Engine service depends on the Redirected Buffering Sub Sysytem service which failed to start because of the following error: SMB MiniRedirector Wrapper and Engine is not a valid Win32 application. (Event ID 7001)
- The Redirected Buffering Sub Sysytem service failed to start due to the following error: Redirected Buffering Sub Sysytem is not a valid Win32 application. (Event ID 7000)
- The following boot-start or system-start driver(s) failed to load: CSC rdbss (Event ID 7026)
As a real IT expert, I tried 5 restarts before trying anything else ;)
So… to resolve this unfortunate issue, I had to use the notorious System File Checker tool (SFC.exe) .
This poorly documented windows utility will scan all protected system files and replaces incorrect (corrupted, changed or missing) versions with correct Microsoft versions and running this from the command prompt is much easier than booting off the DVD into repair mode.
Once you have an administrator command prompt open (click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator), you can run the utility by using the following syntax:
SFC [/SCANNOW] [/VERIFYONLY] [/SCANFILE=<file>] [/VERIFYFILE=<file>]
[/OFFWINDIR=<offline windows directory> /OFFBOOTDIR=<offline boot directory>]
The most useful command is just to scan immediately, which will scan and attempt to repair any files that are changed or corrupted using this command:
The scanning replaced the corrupted system file rdbss.sys and I was back to domain browsing business right after :)
Note: If SFC shouts he can’t repair the corrupted files, than you will have to drill down to the CBS.log to find what is corrupted and replace it yourself
By the way, Marissa Mayer promised that Chrome Browser will be leaving Beta (while GMail is still in Beta…) and it just did yesterday and that Google Search Wiki would soon have a toggle button that allow people to turn it off (“early Q1.”) – I can’t wait… :)

This post is a weird collection of three Internet Conspiracies from the last 24 hours.
Note: I do realize that this post is a creepy testimony to the fact that I might be building a search engine and reading too many blogs and the affect it might have on my sense-of-judgment…
Conspiracy I (Google thinks Facebook is a dangerous Phishing Site)
Google Chrome browsers around the world have claimed today that Facebook is a dangerous Phishing Site (read more on Facebook Developer Forums)
Conspiracy II (Searching for a compatitor ‘search engine’ with Yahoo)
Searching ‘Google’ in Yahoo, results with suggestion to use Yahoo search: “You could go to Google. Or you could stay here and get straight to your answers.” (it also works with ‘ask’, ‘aol’ and ‘live’ :)
Conspiracy III (Apple Anti-Virus or not)
Two weeks ago, Apple updated a technical note on its Support Web site that says:
“Apple encourages the widespread use of multiple antivirus utilities so that virus programmers have more than one application to circumvent, thus making the whole virus writing process more difficult.”
Yesterday, Apple removed the KnowledgeBase article from its support site (KBase Article HT2550 now points to a bare error page – see below) and Apple spokesperson Bill Evans explained:
“We have removed the KnowledgeBase article because it was old and inaccurate… The Mac is designed with built-in technologies that provide protection against malicious software and security threats right out of the box… However, since no system can be 100 percent immune from every threat, running antivirus software may offer additional protection.”

I don’t know if you have noticed but Google launched Search Wiki yesterday.
With Google SearchWiki, signed-in Google users can now customize their search experience by re-ranking, deleting, adding and commenting on search results.
- The re-ranking changes you make are private and only affect your own searches.
- Your comments are visible to the public
Random thoughts on Google Search Wiki:
- You need to be very brave to change usability patterns in your world-leading-search-cash-cow (!)
- Why wasn’t it tested as yet another interesting Google Lab project?
- The arrows “soup” is really too much for the lonely-searcher –> way too many arrows if all you wanted is just search.
- The comments I saw until now are mainly spam or not interesting.
- The most important feature in Search Wiki is a way to turn it off but it is still missing…
- It is a good time to change your default search engine ;)
- Is it only me or Search Wiki have the lively smell all over it?
I must be missing something since the Google guys are very far from being stupid (to say the least) and it will be a very interesting to see if Google will change the search experience yet again with this move.
Update (10 Dec. 2008) : Marissa Mayer promised that Google Search Wiki would soon have a toggle button that allow people to turn it off (“early Q1.”) – I can’t wait… :)

The Dunning-Kruger effect is a cognitive bias in which people who are worst at a task show the most illusory superiority, rating their own ability as above average (e.g. “shut up I hack you“ :)
Justin Kruger & David Dunning have tested and verified the following predictions:
- Incompetent individuals tend to overestimate their own ability and performance
- Incompetent individuals fail to recognize genuine skill in others (it takes one to know one ;)
- Incompetent individuals fail to recognize the extremity of their inadequacy (“One puzzling aspect of our results is how the incompetent fail, through life experience, to learn that they are unskilled”)
- If they can be trained to substantially improve their own skill level, these individuals can recognize and acknowledge their own previous lack of skill (There is still some hope)
Do you have the confidence that this post isn’t about you?
Think again… (!!!) – “ignorance more frequently begets confidence than does knowledge” (Charles Darwin)
Do you think this post is about you?
Might be considered vain but interesting enough, the same research have shown that the top performers tended to underestimate their own performance compared to their peers (see chart below).
So… if you find this post boring, obscure, stupid, annoying, poorly written or inappropriate than please keep in mind it isn’t something I have committed knowingly.

I have missed the latest Google Developer Day due to other obligations (we have uploaded a brand new people directory to the Delver site :) and although the Chrome session by Bill Hesse was very interesting (so I was told), I felt lucky when I saw the email the participants got after the event (a.k.a. “Unauthorized Network Activity at Google Developer Day”)
From: Developer Day <email@example.com>
Date: Mon, Nov 3, 2008 at 11:00 AM
Subject: PLEASE READ: Unauthorized network activity at Google Developer Day
First of all thanks for attending Google Developer Day yesterday, we hope you found it useful. Unfortunately, we need to let you know about an incident which took place during the conference which you may need to take precautionary action on.
We identified unauthorised activity on the public wired Ethernet network which was provided by the convention centre for conference attendees to access the Internet. This may have affected a limited number of attendees accessing websites and online applications through the wired Ethernet connection. We have no evidence so far to suggest that the wireless network also provided at the event, and which was used by most attendees, was affected.
Due to the unauthorised activity, there is a chance that if you used the wired network, any user name and password entered to access a website may have been put at risk. When trying to access a secure website (a website using https), you may have received an alert indicating that the page had an invalid security certificate. In any case, we advise users as a precaution to change the passwords for any websites or services they accessed through the wired connection during the conference.
We’re really sorry that this has happened but we believe that the vast majority of attendees won’t have been affected by this incident. In the meantime, we look forward to seeing you at future events very soon.
The Google Developer Day Team
