Limitation of WebDAV on IIS
IIS 5/6 has a limitation on how WebDAV works and which you should know about before implementing WebDAV.
In the article http://www.windowsnetworking.com/articles_tutorials/WebDAV-IIS.html
on WindowsNetworking.com you can learn how to implement WebDAV for publishing content to IIS web servers. Unfortunately IIS 5/6 has a limitation on how WebDAV works: you can only enable or disable WebDAV on a per-server basis, you can't do it on a per-site or per-virtual directory basis. You should be aware of this limitation before trying to implement WebDAV on an IIS box that hosts multiple websites for different departments or companies.
