IIS 6.0 Device Unavailable on Network Mapped Drive

Greetings:

I have a VB6 COM object that attempts to do the following:

CHDrive "Z"
MKDir "NEWFOLDER"

Where "Z" drive is a network drive mapped under the exact
same user account that the Web Site and Application Pool
is running under; and the remote machine where the share
was made is made under the same userid name and full
privledges are assigned to the userid.

On IIS 5.0 this works fine. On IIS 6.0 I get the Device
Unavailable from the CHDrive command.

Does anyone have an idea why this is ? Further, is there
an easy fix ? If not, I am going to have to develop some
elaborate cross-system file management system.

Thanks,

Robb Murdock

Hi Robb,

Thank you for posting in MSDN managed newsgroup!

For security concerns, services cannot use drives mapped via the credentials supplied by another logged on user. In IIS 5.0, you could potentially
get this to work, but it is not recommended. In Windows XP, Windows 2003 Server, and future versions of Windows, services cannot use these
mapped drives. For more information, see this Knowledge Base article:
INFO: Services and Redirected Drives

You can use FileSystemObject scripting component to connect to the remote folder with the UNC name, for example \\testBox\e$\testFolder. I
write one sample code for you.

'Code begin---------------------------------------------------------
Dim objFS, objFld, objSubFld, folderName

'create one random folder name
folderName = "hello" & 10000*Rnd
set objFS = Server.CreateObject("Scripting.FileSystemObject")

Set objFld = objFS.GetFolder("\\testBox\e$\testFolder")
Set objSubFld = objFld.SubFolders
'Create the new folder for you
objSubFld.Add(folderName)
'Code end-----------------------------------------------------------

Please feel free to let me know if you have any further questions.

Does this answer your question? Thank you for using Microsoft NewsGroup!
