As far as I can tell, I don’t have a web.config, so I would guess I don’t
have impersonation turned on.
As a test, I’ve granted write access on the file and directory to
‘telem\domain users’ and it all springs to life, so it would seem as if the
write is being executed as the authenticated user. The simplest solution
seems to be to move the log file to a directory where I don’t mind granting
write access. Is this the best solution? Any risks?
Regards
