Calling DTS from ASP throught ISA Firewall

I am trying to execute a DTS package from our external web site. The package resides on an SQL Server inside the ISA firewall. I can connect to the SQL Server via ADO but everything else is blocked so the following code will not work since I believe it uses Windows Integrated Security:

Dim oPkg
Dim objCID
Dim objSID
Dim objOrderID

Set oPkg = CreateObject("DTS.Package")

Set objCID = oPkg.GlobalVariables.New("@.CID")
Set objSID = oPkg.GlobalVariables.New("@.SID")
Set objOrderID = oPkg.GlobalVariables.New("@.OrderID")

oPkg.LoadFromSQLServer "ServerName", "UserName", "Password", , , , , "MSIOrder"

objCID.Value = "2303"
objSID.Value = "822105614"
objOrderID.Value = "323"
oPkg.GlobalVariables.Add objCID
oPkg.GlobalVariables.Add objSID
oPkg.GlobalVariables.Add objOrderID

oPkg.Execute
Set oPkg = Nothing

Is there a way to call this DTS package via an ADO connection? And of course, to complicate things, I need to pass the DTS package three global variables.

Lastly, modifying the ISA config is not an option unless I can be absolutely sure that it would not alter our current level of security.

Thanks in advance,
JimDTS? Ick. Anyway, are you sure you have the DTS DLLs installed on the client machine (this case the web server)? I believe you need to install Enterprise Manager on the machine for those DLLs to get installed. No separate installation as far as I know.

Also, what error message are you getting?
