It is more effective when used with Exchange 2003/2007 and Forms Based Authentication, as the users get a web page immediately – and without any authentication prompts – providing a level of confirmation that they have hit the correct address.

1. Start IIS Manager
2. Right click on the “Default Web Site” and choose “Properties”.
3. Click on the “Home Directory” tab.
4. Change the first option to “A redirection to a URL”.
5. Enter “/exchange” in to the box (minus quotes)
6. Change the entry below to “A directory below URL entered”.
7. Click Apply/OK.
If you are prompted about changing child objects, click cancel so that nothing else is changed.
8. Close the IIS Manager.
9. Test.

Filed under: GNU/Linux, Howto — shirwa @ 12:07 am

To make an ISO from your CD/DVD, place the media in your drive but do not mount it. If it automounts, unmount it.

Create iso image with dd comman:

# dd if=/dev/cdrom of=/tmp/cdimage.iso

  • if = input file (/dev/cdrom).
  • of = output file (cdimage.iso)

To make an ISO from files on your hard drive, create a directory which holds the files you want. Then use the mkisofs command. mkisofs -o /tmp/cd.iso /tmp/directory/

This results in a file called cd.iso in folder /tmp which contains all the files and directories in /tmp/directory/.
