Hi

I have a query, i have put the code here.

I am using VS 2005, C#.Net.

This is working fine when i am install the Win OS 2003 with ADS, but

after few days it starts entering the exception and gives the message
"

Logon Failure : unknown user name or bad password"

I am a bit confused and want to know the reason for this.

Can someone help me and let me know the reason and solution for this

because i cann't reinstall the OS all the time.


//  Start of Code


                using (DirectoryEntry deDirEntry = new

DirectoryEntry("LDAP://" + UserDomainTextBox.Text,


UserNameTextBox.Text,


UserPassTextBox.Text,


AuthenticationTypes.Secure))

                try
                {
                    string name = deDirEntry.Name.ToString();

                    MessageBox.Show("Welcome to '" + deDirEntry.Name
+

"'");

                }
                catch (Exception exp)
                {
                    MessageBox.Show("Sorry, Invalid User");

                }

//  End of Code


Thanks for the help
