i was using 7.01 and still am for the chewforum url (which still works fine)
the settings for the upload are still correct and i have tried reapplying them just incase something strange happened.
the uploads directory has full control access through explorer for the everyone group and i have even tried allowing write access through iis admin (which never had to be done in the past)
the directory was never deteled only the new asp files placed into existing directories so i don't see that the permissions should have changed at all.
i've even gone as far as rebooting the server incase iis had got itself in a muddle.
is there any debugging information that can be turned on or anything to see where it is getting stuck?
