Problem opening up Windows explorer from a web page with vbscript

[justsaynik]

Hi,

I am not good at VBScript. I am able to launch word application(from a web page on button click) on client machine using the below script

<SCRIPT LANGUAGE=VBScript>
Dim objWord
Sub Btn1_onclick()
call OpenDoc("http://MyServer/MyTest.doc")
End Sub

Sub OpenDoc(strLocation)
Set objWord = CreateObject("Word.Application")
objWord.Visible = true
objWord.Documents.Open strLocation
End Sub
</SCRIPT>
<INPUT TYPE=BUTTON NAME=Btn1 VALUE="Open Word Doc">

But i am unable to launch the windows explorer in the client machine using the below code..... permission denied error is being dispalyed.

<SCRIPT LANGUAGE=VBScript>
Sub Btn1_onclick()
Set objShell = CreateObject("Shell.Application")
objShell.Explore "ftp://username : passwd@host/"
End Sub
</SCRIPT>
<INPUT TYPE=BUTTON NAME=Btn1 VALUE="Open Explorer">

Please help... Thanks in advance
