strange 404 in ASP.NET IIS5

I have been receiving this very strange 404 lately and was wondering
if anyone else out there has had a similar problem. For some reason
when users receive this error and they hit refresh the error goes
away. Seems like a IE or ASP.NET cache problem, but can not find any
articles on it.

404 not found C:\inetpub\mySite\mySite_com_files\pictures.aspx

-MikeOh yeah, sometimes instead of mySite_com_files it will be a username_com_files or username_files. _files is on all these 404's no matter what was before it.
