I want to reset the Password of users of Company 2 who are in Windows NT domain with a web application using ASP.NET 1.1 with C#.
Is the below code works fine or do I need to try some thing else, please helps me with this request.

DirectoryEntry de = GetDirectoryObject();
DirectorySearcher deSearch = new DirectorySearcher();
deSearch.SearchRoot = de;
deSearch.Filter = "(&(objectClass=user)(sAMAccountName=" + UserName + "))";
deSearch.SearchScope = SearchScope.Subtree;
SearchResult results = deSearch.FindOne();
if (!(results == null))
{
de = new DirectoryEntry(results.Path);
return de;
}
else
{
return null;
}
}

///<summary>
/// This method enables account in AD
///</summary>
///<param name="oDE">directoryEntry - oDE</param>
private void EnableUserAccount(DirectoryEntry oDE)
{
oDE.Properties["userAccountControl"].Value = _userStatus.Enable;
oDE.CommitChanges();
oDE.Close();
}

///<summary>
/// This method enables resetting password on next login
///</summary>
///<param name="oDE">directoryEntry - oDE</param>
private void EnableResetPasswordNextLogin(DirectoryEntry oDE)
{
oDE.Properties["pwdLastSet"].Value = 0;
oDE.CommitChanges();
oDE.Close();
}

///<summary>
/// This method resets user password
///</summary>
///<param name="oDE">directoryEntry - oDE</param>
///<param name="Password">string NewPassword</param>
private void SetUserPassword (DirectoryEntry oDE, string Password)
{
object ret = oDE.Invoke("SetPassword", new object[] {Password});
}

///<summary>
/// This method enables account in AD
///</summary>
///<param name="userName">string userName</param>
public void EnableUserAccount(string userName)
{
try
{
EnableUserAccount(GetUser(userName));
}
catch(Exception ex)
{
log.Error(ex);
throw;
}

}

///<summary>
/// This method enables resetting password on next login
///</summary>
///<param name="userName">string username</param>
public void EnableResetPasswordNextLogin(string userName)
{
try
{
EnableResetPasswordNextLogin(GetUser(userName));
}
catch(Exception ex)
{
log.Error(ex);
}

}

///<summary>
/// This method sets new password in AD
///</summary>
///<param name="userName">string Username</param>
///<param name="newPassword">string Password</param>
public void SetPassword(string userName, string newPassword)
{
try
{
DirectoryEntry de = GetUser(userName);
SetUserPassword(de, newPassword);
de.CommitChanges();
}
catch(Exception ex)
{
log.Error(ex);
throw;
}

}
