The problem may not be with the UNC nature of the path you are trying to access, but with security credentials. If, for example, you run the asp.net application under the System account, you will not be able to access network resources, because the system is a local account (and not a domain account).

I suggest you check inetmgr under which your application pool works (under the Identity tab). Try using a domain account that can access this resource.

The account "responsible" when issuing a request to access the file simply does not have to have credentials to access the resource / resource found in the UNC location.

The solution is supported by the impersonation and delegation of asp.net functions. There are certain constructs that provide a token-based security scheme for invoking the file.copy operation, for example, for a purpose that is a UNC location. You can check it out here .
