Multiple File copy to Web Server

P: n/a
Hi,
Long time reader, first time poster... Any help is appreciated.

I have a few questions regarding Winform controls embedded within an
html page. For more info please see the appendix. Now, for the
questions.

1. A button on my control executes the
System.IO.Directory.GetDirectories funtion (the scanned directory
resides on the hosting web server). What credentials is this
accomplished with from the client machine, the users windows login or
a .NET machine account? Can these credentials be changed (kind of like
an impersonate in ASP.NET)?

2. I have a button on my control that executes the System.IO.File.Copy
method (again the "copy to" directory resides on the hosting web
server). Same questions as above regarding credentials...

3. Ideally I would like to authentice the user and then execute the
remainder of the controls file functions under the identity of a
specific AD account (one such that the users do not even know exits).
Is this possible?

Please keep in mind this all executes on the client machine and does
not utilize ASP.Net.

Appendix
The Original Problem:
1. Copy multiple html, htm, css, jpg, jpeg, gif, etc,.. files from a
client machine to two web servers (they are load balanced) within our
company intranet.
2. Use AD for authentication purposes.

Requirements:
1. Provide a browser based solution (these people want WEB, WEB, WEB).
2. Scan the "Dept" folder on one of the hosting web servers. Extract
the names of all department folders within the "Dept" folder to aid in
authentication purposes. This is accomplished by appending the string
"_Pubs" to the end of each department name (thus creating the AD OU)
and using "myPrincipal.IsInRole("domainname<i>\" + Dept + "_Pubs")
3. For users that log into the domain, authenticate against their AD
OU (<i>deptname_Pubs).
4. For users that do not log into the domain, prompt for credentials
then authenticate against their AD OU (deptname_Pubs).

My Solution:
Use a Windows Form Control within an html page. Utilize the System.IO
class for all file scan and copy functions. Utilize the
System.Security.Principal class for active directory authentication.
Note: This solution works perfectly for me because I am an
administrator on the web servers. My users will not be.

Below is the relevant code for anyone interested. Some of the names
and code have been changed to protect the innocent:
