File Upload issues with WebClient.Uploa dFile

[Phillip N Rounds]

I'm having problems using the WebClient.Uploa dFile() command.
I have MySender.ASPX which is supposed to upload two files to the server.
There is also ConsumeFileUplo ad.aspx which is intended to handle receipt of
the files. Pertinent code for each is below.

When I run the process locally in debug mode, everything works great (
VS.NET 2003 , ASP 1.1 ).
When I run locally on the server, everything works great.
When I try to remotely upload files, I get an error: THE REMOTE SERVER
RETURNED AN ERROR: (500) INTERNAL SERVER ERROR

I have given both ASPNET & NETWORK SERVICE Write/Modify permissions in the
target directory.

Any Suggestions

Button_Click in MySender.ASPX

string Small = "c:\\MySmall.jp g";
string Large = "c:\\MyBgPictur e.jpg";
System.Net.WebC lient MyWebClient = new System.Net.WebC lient();
string URI="";
string SUBDIR = "";
util.GetLocatio nSettings( ref URI, ref SUBDIR);
string uri = URI + "/" + SUBDIR + "/ConsumeFileUplo ad.aspx";
uri.Replace("//","/");
try
{
byte[] by = MyWebClient.Upl oadFile( uri , "POST", this.Small);
byte[] by2 = MyWebClient.Upl oadFile( uri , "POST", this.Large);
}
catch ( Exception ex )

EventLog log = new System.Diagnost ics.EventLog();
log.Source="LGS .AddProducts";
log.WriteEntry( ex.Message);
log.Close();
}
}

your remote server probably requires nt authenication. if you conect to your
webserver locally, it can use your network creditials because it has a
primary token. if it is not a local connection, then is has a secondary
token which can not be used for any network resource.

set you webserver to use a known domain accout with permission to the remote
server,. or switch to kerberos.
