sharepoint designer

Hi all,

I am unable to open the sharepoint designer 2010 .

I receive a message saying that an ” error occurred while trying to fetch data from your sharepoint site.Unexpected response from the server. The Content type of the response is “”. The Status code is “OK”.”

I tried many related solutions and here are few of them:

• Enabled designer settings in central admin for the web application in path >> Central Administration | General Application Settings | SharePoint Designer

• Also checked the SharePoint Designer settings for the site under(for particular site collection) Site Settings | Site Collection Administration | SharePoint Designer Settings

• Few IIS settings like changing authentication to windows and ”, added its providers to “NTLM” in addition to “Negotiate:Kerberos” and “Negotiate”

• Finally, tried by reinstalling SPD but it couldn’t help in fixing the issue ,rather than that I have tried some multiple ways to Nothing above works, is there any other thing i am missing, any help on this is appreciated

Thanks in advance Anusha
