Cohosting other web sites on the same server as the application tier of Visual Studio® Team Foundation Server (TFS) is a common request and while it is not our typical scenario it is fairly easy to configure with IIS 6. Once you configure the IIS settings you will be able to install other web applications on the same IIS server and using the same TCP port (e.g. port 80). This is accomplished by configuring the host headers in IIS so that IIS will point Team Explorer and sharepoint requests to the correct web site.
