You should already have full Read and Write permission to your root and all the folders and files under the root. From what we have experienced and seen on postings in this forum, the error is misleading and often indicates a trust level issue. Try increasing the trust level on your application from Medium to either High or Full. Refer to this kb article. http://support.Winhost.com/KB/a657/changing-the-default-aspnet-trust-level.aspx
