An impersonation error occurred using the security context of the current user. -- Report server is on remote server and file share folder is on local server

I have deployed a report on the server (e.g. remoteserver\reports) from my local machine. I opened the report in browser in my local machine and created a new subscription with windows file share delivery option.

But its giving an error "Failure writing file \\localserver\subscriptions\Report1.xls : An impersonation error occurred using the security context of the current user." Here "subscriptions" is the folder which I have created in my local machine.

I followed the instructions found in the link "http://msdn.microsoft.com/en-us/library/ms157386.aspx"

Please help to solve this issue.
