FSO Server.MapPath to a DFS share

Hello -

I need a little help with my VB/ASP page. I posted my first question in the VB forum, but I think posting it here is a bit more relevant.

Basically, I'm creating a script that looks for a particular file in a specific directory, then launches it (if it exists). I need for the Server.MapPath to point to a DFS share, but I'm having trouble making this, or any path that leads to an alternate directory (outside of the ASP page's home directory) work correctly.

Here's the code:

Dim strPrinter
Dim strPrinterName
Dim FSOPrinter

strPrinter = Request.QueryString("Printer")
strPrinterName = Request.QueryString("PrinterName")

Set FSOPrinter = Server.CreateObject("Scripting.FileSystemObject")
If FSOPrinter.FileExists(Server.MapPath(strPrinter & ".pwc" )) Then
Response.Redirect(strPrinter & ".pwc")
Else
Response.Write(strPrinter & " is an invalid printer name.")
End If

Can someone please help!?
Thanks,
DesertSky

OK, script modified as follows:

If FSOPrinter.FileExists(Server.MapPath("/testing/" & strPrinter & ".pwc")) Then
Response.Redirect("/testing/" & strPrinter & ".pwc")

Got it working, still no luck with the DFS share - I suspect my syntax is wrong...I'll continue researching. If anyone knows how to correct this problem in the meantime, please let me know.

Thanks!
