IIS 6.0 Unique ID generation

Hi,

As everybody knows, IIS 6.0 assigns unique IDs based on the specified web
site name. I have been developing an programmatic administration tool for
IIS 6.0 and I need the algorithm how IIS generates these identifiers. I have
been through MSDN and Google search but have nothing usable.

Using the administration APIs you can easily enumerate available websites,
locate ones matching your criteria, and retrieve its ID.

Can you please give the reason(s) why you need to be able to predict the
Website ID before creating the website? Are you also aware that you can
actually specify the ID for a website (you get an exception if the ID is
already used)?

Anyways, I cannot think of a reason why anyone needs to know the algorithm,
including Microsoft...

I am hosting multiple web sites on a w2k3 server and want to create web
sites through an application to reduce the time spent for web site creation.
In order to create new web sites I need to assign an empty ID for
System.DirectoryServices class, so that it can create a new web site with
that ID. I could easily enumerate used IDs and generate one that is not in
use and create the new site with that ID but I know MMC uses an algorithm to
generate IDs with respect to the ServerComment property (or website name)
and I want my aplication to use the same procedure for the sake of
compatibility. This is the reason.

PMJI, but what happened to the sensible, logical method of assigning W3SVC
IDs that IIS 5.0 had? Now that I've upgraded to IIS 6.0, I get what appear
to be random 10 digit W3SVC numbers when I create new websites. Makes it a
little more difficult for the human being (me) to locate web server logs,
etc. What were they thinking?

This is for security, so that attackers are unable to guess. say if I have
two website, it won't be site id 1 and 2. it can be anything ...

I'm not a dev guy. but I don't think it needs the ID to create the website.
take a look at the built-in script.

IISweb.vbs

try iisweb /create

it only ask you for the web root path, site description, ip, port, and host
header name.

Hello,

You can use IIsWebService.CreateNewSite to create new sites. This is new for
IIS 6.0.

I think the SDK is a bit vague on this, because the examples you can find
that creates new websites does not use this.

ADSI:
http://msdn.microsoft.com/library/en-us/iissdk/iis/iiswebservice_createnewsite.asp

WMI:
http://msdn.microsoft.com/library/en-us/iissdk/iis/ref_mof_iiswebservice_createnewsite.asp

Hope this answers your question.

iisweb.vbs (in the code) uses IIsWebService.CreateNewSite to create new
websites on IIS 6.0.

Just for your interest :-)

Thanks.

iisweb.vbs uses WMI to add new web sites. Since I do not have any experience
with WMI and all WMI the examples uses either VBScript or JScript I am not
able to produce a solution this way.

System.DirectoryServices examples tell me that it is required to provide an
ID to create site.

Thanks. It seems I will need to study on ADSI and WMI. I have been focused
on System.DirectoryServices but have not found the solution there.

Documentation on these matters is either quite poor or I do not know where
to look...

Hello,

I wrote some quick code that creates a new website using CreateNewSite in C#
that my be of interest. You can find it here:
