Apache won't start after adding some lines in httpd.conf

[RandV]

I wasn't sure if I should post this in a XAMPP or Symfony forum, but since I have the XAMPP error log figured I'd try here. I'm trying to setup a better php development environment on my desktop utilizing a framework, and have been following a guide from this blog:
http://hazraphp.blogspot.ca/2009/09/symfony-on-xampp.html
(note: not sure how to make something a link on this forum, <a> tags don't seem tow ork)

Following the instructions near the end I was told to add these lines to the apache httpd.conf file, the directories of course have been changed to match my file system:

# Use name-based virtual hosting.
#
NameVirtualHost *:80

#default area for new web projects

ServerName web
DocumentRoot "B:\web"

#original xampp location

ServerName localhost
DocumentRoot "B:\xampp\htdocs"

#allow access for the shared sf directory

Allow from All

#sample symfony project

ServerName askeet
DocumentRoot "b:\web\askeet\web"
DirectoryIndex index.php
Alias /sf "b:\xampp\php\pear\data\symfony\web\sf"

AllowOverride All
Order allow,deny
Allow from All

Now when I run XAMPP and start apache, I get the usual:

11:45:56 PM [Apache] Error: Apache shutdown unexpectedly.
11:45:56 PM [Apache] This may be due to a blocked port, missing dependencies,
11:45:56 PM [Apache] improper privileges, a crash, or a shutdown by another method.
11:45:56 PM [Apache] Press the Logs button to view error logs and check

11:45:56 PM [Apache] If you need more help, copy and post this
11:45:56 PM [Apache] entire log window on the forums

And the error log says:

I'm trying to decipher it but as I'm a first timer with this it still looks like gibberish to me. Would be much appreciated if anyone can see what I'm doing wrong here?

Well easier said than done, the tutorial I have is the most detailed step by step example I found... though yes it sucks it's from 2009, but I was able to work around that for the most part. I'll just take the question to an Apache forum, thanks.

No, it not only sucks because it is old. It sucks because it is broken. Important directives like <VirtualHost> are missing (maybe because of HTML tag filters of that blog)
