I am making a web service which accesses a shared directory on the netwoek to
upload a file there. Here comes the problem, When I use impersonation and
give the userName & password of an authenticated user, then it works fine but
when I impersonate, using ASPNET account of the machine where web service is
being hosted then the whole uploading process fails. As, it also exposes the
password in clear text format, it is also not acceptable. Also, if I make a
group on the machine where directory is shared, then again I cannot add the
ASPNET user account of the machine where web service being hosted, in that
usergroup.

So is there any solution for the above problem? All the suggestions and
queries are welcome.
