This is a virtual lab environement under Windows Server 2008 R2 Hyper-V. The virtual machines are Windows Server 2008 R2; I've got SharePoint Server 2010 Enterprise Edition and SQL Server 2008 R2 on one machine; Active Directory with Exchange on another, and a Windows 7. Everything works as it should, including SharePoint. However.
When I click "Edit in SharePoint Designer" under Site Actions, there's a few seconds of "Loading..." and then I get the following (in a "pop up web page"): Internet Explorer cannot display the webpage.
It does not matter which user (lever or privileges) I use, or on which machine (client, server) I try, it is the same.
I've googled this, but have not found anyone else with this problem. On the other hand, you get a lot of "false positives" with the keywords involved.
Any help much appreciated.
