Err.exe says that 0x800708C5 = "password too short". Are you sure the
password you tried to use is in compliance with your password policy?

Also, remember that ChangePassword always throws a TargetInvocationException
with the real exception in the InnerException property. This is because
ChangePassword is called via Reflection.

HTH,

Thanks,Joe K.
But, question is that I want to use short password. But it is not allowed.
So I think I need to change the password policy. After I changed the
password policy in 'Group Policy Editer', I succeed to change password
which is short in Active Directory. But it also can't be allowed through
running my program. I also recieve the same error. I don't know why and how
I can do.

And there a new question.
To solve the original question I try other way. I am invoking the
'SetPassword' method (replace the 'ChangePassword' method) on the
DirectoryEntry object, and use 'administrator' status. This successfully
changes the passsword for the user and I can login with the new password.
It is short password.
But, question appear, the old password is also valid so I can login
with either the new or old password. When I close the page and exit program
environment, or logout, the old password is invalid.

This is code.
-------------------
string adpath = "LDAP://" + ConfigurationSettings.AppSettings["MydcCom"];
string[] strADAdmin = ConfigurationSettings.AppSettings["ADAdminString"]
..Split(new char[]{','});

//strADAdmin[0]--administrator; strADAdmin[1]--password
DirectoryEntry entry = new DirectoryEntry(adpath, strADAdmin[0], strADAdmin
[1]);
DirectoryEntry userEntry = new DirectoryEntry();
try
{
object obj = entry.NativeObject;
DirectorySearcher search = new DirectorySearcher(entry);
search.Filter = "(SAMAccountName=" + loginName + ")";
search.SearchScope = SearchScope.Subtree;
search.CacheResults = false;

SearchResultCollection results = search.FindAll();
foreach( SearchResult result in results )
{
userEntry = result.GetDirectoryEntry();
break;
}

if( userEntry != null )
{
userEntry.Invoke("SetPassword", new object[]{newPwd});
userEntry.CommitChanges();
}

return true;
}
-------------------

Thanks.
