Unable to open Web site. Possible causes:
1) the Web server may not have SharePoint Server installed.
2) The Web server may be temporarily out of service.
3) If you are connecting through a proxy server, the proxy settings may be incorrect.
4) An error may have occurred in the Web server.
Same error when trying to use SharePoint Designer 2010 from Windows 7 or on the Windows Server 2008 R2 (VMWare). Then trying to launch SharePoint Designer 2010 from with Site Actions.
Only one binding exists. The designer settings are checked under General Application Settings.
Using Fiddler, I noticed a HTTP 400 with "The parameter is incorrect" under hexview.
This is a brand new VMWare hosted server with a licensed version of SharePoint 2010.
Any help would be appreciated.
