I have a web page to upload a file. The upload works fine when uploading to
a local drive.
When I attempt to upload to a mapped drive I get the following message:
Logon failure: unknown user name or bad password.....
I have read many articles about security settings that may apply.
I tried setting impersonation to true as follows in the web.config file:
<identity impersonate="true"/>
This gave me the following error:
Access is denied: 'Hipaa'. - Hipaa is my DLL (a called module)
So, I also tried this:
<identity impersonate="true" userName="Administrator" password="xxxyyy"/>
This option gave me the following error:
'A required privilege is not held by the client. '
So, I tried setting the IUSR_machinename and ASPNET user priviledges in
local policies to
'Act as part of the operating system'
That didn't help either.

Can anyone help me????
