CAUSE
The control did not properly handle the Username and Password.

Steps to Reproduce Behavior
 Start a new Standard EXE project. Form1 is added by default. From the Project menu, choose Components, and select the Internet Transfer Control 5.0(SP2) into the project if it is not already loaded.  Place an Internet Transfer Control 5.0(SP2) on Form1 and add the following code:

Private Sub Inet1_StateChanged(ByVal State As Integer) Const lCHUNKSIZE As Long = 1024 Dim vtData As Variant ' Data variable.

Select Case State ' ... Other cases not shown. Case icError ' 11 ' In case of error, return ResponseCode and

' ResponseInfo. vtData = Inet1.ResponseCode & ":" & _ Inet1.ResponseInfo

Case icResponseCompleted ' 12 Dim strData As String: strData = "" Dim bDone As Boolean: bDone = False

' Get first chunk. vtData = Inet1.GetChunk(lCHUNKSIZE, icString) DoEvents

Do While Not bDone

strData = strData & vtData ' Get next chunk. vtData = Inet1.GetChunk(lCHUNKSIZE, icString) DoEvents

If Len(vtData) = 0 Then bDone = True End If          Loop

MsgBox strData End Select End Sub

  Place a CommandButton (Command1) on Form1 and add the following code:

Private Sub Command1_Click Inet1.UserName = "Username" Inet1.Password = "Password" Inet1.URL = "ftp://YourFTPServer" Inet1.Execute, "DIR" End Sub

 From the Run menu, choose Start (ALT, R, S), or press the F5 key to run the program. Press the Command1 button and you will see error described above.</ol>
