IIS WebService Login Security?

I like .NET Web Services, but I don't like the actual .asmx page in full view to the world.

So I changed the Authentication Method from the default Anonymous to Integrated...

Now I must include a username, password, domain within the Web Service Client (Windows App)
in order for my clients to access the Web Service...

Problem: I will need to change the IIS password regularly, so the hardcoded (Windows App) password will become uselss.

I hardcode to send authentication to IIS because I cannot get a default IIS Auth Window to popup.

Not sure how to proceed, help???

Who access the Web service? If it's on a private network, then you could stick the Web service into an IIS root that only allow those IP addresses.
If it's a public service but only a few sites can call it:
1. If you know their IPs, use that to block all requests but those IPs
2. If IP is not reliable, you could pass a U/P to the Web service (using https if that information is sensitive)

If you do either of those, put back Anonymous for your Auth method.

I'm missing a bit of information to help you all the way, but I'll try.
So I'm assuming you are putting your Web services in the same directories as your website.
So www.mysite.com/MyService.asmx right?

If www.mysite.com is also used for other content that's publicly available, then you need to segment the sites:
service.mysite.com and create a Web just for those, or at least stick them in a sub-directory like www.mysite.com/WebServices/MyService.asmx

Then Go to IIS.msc
1. Open up Web sites and then either
a) Right-click your service.mysite.com Web
b) Or Open up www.mysite.com and right-click the WebServices directory
2. Click the Directory Security Tab and under IP address and domain name restrictions click the Edit button
3. Select Denied access instead of Grant access this will deny everyone
4. Then cllick Add and add allowed IPs, this will then Deny all IPs except the ones listed.
5. Ok everything
6. Enjoy :)

I need to find a programmer who might know where to start on adding these IP programmatically.
