IIS 7.0, a new web publication service, comes as a part of Microsoft Windows Server 2008.

Attention: Currently, the Document library (webdav) module works improperly on web servers controlled by IIS 7.x. The architecture of such web servers in its basic variant does not permit organizing the work of PHP scripts according to the WebDav protocol – the server picks up all the requests and they fail to go through to the Bitrix24 system.
