Presenting Video Files Over HTTP on CIFS

Note: This could be any file really, just happens to be video files for this post.

It has been a long time coming, but here’s a post that is more Microsoft based than what I normally write about …

Essentially, we have a CIFS share with videos in, and to test if there’s any difference in behaviour accessing videos over the share, we want to setup IIS 6 (Windows 2003 R2 SP2) and IIS 7 (in Windows 2008 R2 SP1) to allow web-based delivery of these video files.

The IIS 6 Setup

Note: We can leave the Default Web Site with the default settings (which include anonymous authentication enabled and no directory browsing.)

Firstly, right-click the Default Web Site, and choose New > Virtual Directory... (saves reconfiguring the Default Web Site - leaves it untouched)

Follow through the wizard giving an alias of say ‘videos’:

For the web site content directory we enter the share path name:
Note: Test you can get to this share first via Windows Explorer.

For the credentials, since this is going to be a video repository that anyone can get to, un-tick the ‘Always use the authenticated user’s credentials’ and enter a user name and password which has access to the share, and NTFS permissions to the files

All we need is read permissions (we’ll add browse too, this isn’t a requirement though.)

And Finish!

That’s pretty much it. If we have a video called movie.mpg and our web server is called IIS6, the following link should open up with the movie:


The IIS 7 Setup

The IIS 7 setup is pretty much identical.

Firstly, right-click the Default Web Site, and choose Add Virtual Directory...

Enter ‘videos’ for alias, enter the physical path (the share), click on ‘Connect as...’ and provide the login.

And that’s it (we don’t even need directory browsing, and by default it selects anonymous authentication.) A link like the below should deliver our movie.


Miscellaneous Bits

Titbit 1:

Unrelated note (but we like it anyway) - just something discovered in the process of writing this - take it for a spin:

To create a local windows user in Windows with a random password (displayed on screen) via the DOS shell>
net user “xerxes” /add /random

Titbit 2:

No post can escape without a little of my passion for NetApp ... Of course, the CIFS share in question was on NetApp storage, and the main purpose of my lab was to convince myself a problem was an IIS configuration issue ...

Some commands to investigate CIFS share permissions, and more, on NetApp Clustered ONTAP:

set diag
cifs options show -vserver svm1
export-policy rule show -vserver svm1 -policyname default -instance
vserver name-mapping show -vserver svm1 -direction win-unix
vserver name-mapping show -vserver svm1 -direction unix-win
cifs share show
vol show -fields policy,junction-path,junction-parent

Note i: Volumes/Qtrees acting as just CIFS shares would usually have the default export-policy.
Note ii: Only using set diag here because it usually gives more detail in the output.

  1. You have a typo in the post. the URL should be "http://IIS7/videos/moive.Mpg"
