Permission Denied on UNC path via ASP

I’m trying access a file located in a virtual directory on another server but I keep receiving a Permissions Denied message when running an ASP program on a browser. I tried numerous approaches, including creating the IIS4 IUSR_servername account on the remote server using the same password, all to no avail. Some doc says this is not supposed to work, other doc says the above way is supposed to work. Have you successfully accomplished accessing a remote share via an ASP program?
