.Net C# webservice related

[Meena]

I have a webservice which connects to an Active directory and performs
manipulation of the data in the AD. I want only authenticated users to
connect to the webservice. Unauthenticated users should not be able to access
the web service. If a user tries to access the web service from the URL he
should be prompted with a login authentication before seeing the functions
within the web service. If the user tries to connect to a web service from an
application by adding web reference, there also we need some mechanishm to
authenticate the user who is trying to contact the web service. How to
acheive this?

Hi Meena,

I doubt whether MS project (the subject of this NG) will be of much help.
