Hi Jos,

Sorry for letting you wait for so long time.

Actually, "The Network path was not found" exception may caused by a lot of
reasons.

Is your ADSI code execute in winForm application or Asp.net server side
application?
Can you show me the full code of your application?

To have a background description of "Password-Change Protocols in Windows
2000", please refer to:

also refer to:
"HOW TO: Enable SSL for All Customers Who Interact with Your Web Site in
Internet Information Services"

First, you may try binding to the AD using cached credentials like:

DirectoryEntry user = new
DirectoryEntry("LDAP://cn=joe,cn=Users,dc=.....", ADUser, ADPassword,
AuthenticationTypes.Secure);
user.Invoke("SetPassword", new object[] {"Pa55W0rd123"});
user.CommitChanges();

Also, this problem may due to the DNS setting of your machine.

ADSI is built on LDAP which is built on TCP, after capturing a few network
packets, the server was attempting to resolve a machine name (via DNS) and
failing. Checking the DNS settings on the server revealed a
misconfiguration. Correcting the DNS settings may eliminate the error
message.

At last, if it still does not work, you may try to use WinNt provider to
have a try.

Thank you for your patience and cooperation. If you have any questions or
concerns, please feel free to post it in the group. I am standing by to be
of assistance.

Hi, thanx for your answer.

The environment is this:

Server :Windows 2000 Server= Domain Server- AD.
Development : Windows 2000 Professional. IIS.
Development machine is trying to set the password of a new User.

We can:

1.- Add an user to Active Directory.
2.- Enable that user.

We are not able to Set or change password.
My ADSI code is being execute in ASP.Net.

This is the code:


DirectoryEntry entry = new DirectoryEntry("LDAP://sofia/CN=Users,
DC=sofia,DC=domain,DC=com", "admin","pwdAdmin", AuthenticationTypes.Secure);

DirectoryEntry usuario = entry.Children.Add("cn=" +
txtUserNameI.Text,"user");

usuario.Properties["sn"].Add(txtUserNameI.Text);

usuario.Properties["name"].Add(txtUserNameI.Text);

usuario.Properties["userPrincipalName"].Add(txtUserNameI.Text);

usuario.Properties["samAccountName"].Add(txtUserNameI.Text);

usuario.CommitChanges();

entry.CommitChanges();

usuario.Invoke("SetPassword",new object[]{txtPasswordI.Text});

usuario.Properties["userAccountControl"].Value = 0x10240;

usuario.CommitChanges();

entry.CommitChanges();


I think the problem is SSL, the Question is... I need to configure the SSL
just in the AD Server? or I need to enable it too in the IIS Machine?

Thanx !!! =D

Hi Jos,

Thanks very much for your feedback.

As I think, you problem is most possible caused by 2 factors: the SSL or
the DNS setting.

Based on this article(I have pasted in last reply) "Password-Change
Protocols in Windows 2000", it states:
"When you are using LDAP (method 5), the domain controller and the client
must both be able to use 128-bit SSL to protect the connection."

So you should enable the SSL for both client machine and your server
machine.

Thank you for your patience and cooperation. If you have any questions or
concerns, please feel free to post it in the group. I am standing by to be
of assistance.
