SecurityAccessDeniedException-Access Denied -WCF Service

Question

Hi,
         I have a IIS hosted WCF Service. I am accessing it from remote machine. I get the following error in my client application:
System.ServiceModel.Security.SecurityAccessDeniedException: Access is denied.

I use BasicHttpBinding. Authentication mode is set to "None" in web.config.

Please help

Hi  Rajalakshmi,



I would suggest you to verify if the account under which your service runs has all the required privileges on the server. If you hosted your services on windows 2003,  one way is to add the account under which your IIS application pool runs  to  IIS_WPG windows group so that all the required file system privileges will be granted ( ex: access privileges for Temp folder in windows etc)



I would suggest you to enable trace for WCF service to narrow down the issue. Please refer to the instructions given below to configure and view trace

This should give us more insight in to the issue...

This exception gets triggered when an "Access Denied" fault response is encountered. The most common reason for this is an unhandled SecurityException somewhere in your code.

Thanks. The issue was the service account didnt have write permissions on a path. It is resolved.
