I have an aspx page that is set up to copy backed-up DB files from a shared
directory to a local folder. For some reason, it is being denied access to
the network share. I have the web app running under a domain account that I
know for a fact has access. it works fine when I log on to the network and
browse the directory manually. Even when I grant full control to everyone on
the share and the underlying folder itself, I still can't access it through
code. The funny thing is though, this same code works fine when executed
within a windows service which runs under the same domain account. Help!
Code follows:

The crux is (and its a pain to get working) that using Anonymous
authentication (so no impersonation) the local ASPNET account has to have
the same credentials (username and password) on both machines in order to
delegate security. With basic authentication and impersonation you need to
use a domain account which can delegate and you can check how to mark your
impersonated account able to use security delegation here:
http://msdn.microsoft.com/library/d...>
NetHT05.asp.
This is also required if you want to use NTLM authentication over kerberos
Personally, I would implement a the remote server as an http device and use
http requests, checking the referrer whihc makes life a lot simpler than
using mapped network drives.

Another MVP has written a great article about this
http://west-wind.com/weblog/posts/1572.aspx
The crux is (and its a pain to get working) that using Anonymous
authentication (so no impersonation) the local ASPNET account has to have
the same credentials (username and password) on both machines in order to
delegate security. With basic authentication and impersonation you need to
use a domain account which can delegate and you can check how to mark your
impersonated account able to use security delegation here:
http://msdn.microsoft.com/library/d.../SecNetHT05.asp.
This is also required if you want to use NTLM authentication over kerberos
Personally, I would implement a the remote server as an http device and use
http requests, checking the referrer whihc makes life a lot simpler than
using mapped network drives.

Problem solved! All I had to do was set "identity impersonate" to "true" in
my web.config. Thank you so much!

Problem solved! All I had to do was set "identity impersonate" to "true" in
my web.config. Thank you so much!

System.IO.File.Copy not copying and no error
I'd suggest wrapping the copy in a Try/Catch block just to be sure. Then
throw a new exception, outputing your source/destination paths along with
the original exception:
Try
System.IO.File.Copy(Source,Dest)
Catch ex as exception
throw new Exception("Source: '" & source & "' - Dest: '" & dest &
"'",ex)
end try
also, put a break point at the Throw, and examine your variables.

ah yes i neglected to mention that i already did that, and the value

it fails...
damn i hate this stuff!!!

System.IO.File class and IP paths?
I try to use System.IO.File.Copy where the source is
"\\10.100.100.1\myfolder\test.txt"
When running the aspx file on the server (the server is
also the client) it works, but when using another NT
client it does not work.
The err.description says "Could not find file ..."
System.IO.File.Exists return false here.
But If I manually paste in \\10.100.100.1
\myfolder\test.txt in the IE address field and press "Go"
the file is found.
Strange or not?Hi,
I don't think that the default asp.net user got rights to access network
resources.
