Accessing V without VPN


Accessing V without using the VPN

It is possible to connect to the V drive without using the VPN, using a protocol called WEBDAV.  In this case, it is not possible to assign a drive letter (in Windows XP; this has changed in Windows 7), so the drive is accessed through the My Network Places icon.  Files can be read and written, just as when using the VPN and a drive letter.


Necessary Preparations

Before the V drive can be connected using WEBDAV, two preparations have to be put in place.

Details of each of these follow; once done, they do not need to be repeated.

Starting the WebClient service

The WebClient service is a Windows process that handles access to files using the WEBDAV protocol.  It is disabled by default in Windows XP, so it is necessary to enable it and to set it to start automatically.

Right click My Computer (on the desktop or the start menu, depending on your system)
From the menu select
Manage
Click the
[+] next to Services and Applications
Select
Services
In the right-hand pane, scroll down to
WebClient
If the Status and Startup Type are
Started and Automatic, nothing needs to be done
Otherwise, double-click
WebClient to open its Properties
In the dropdown list for Startup Type, Select
Automatic
Click
Start to start the service
Click
OK to close the properties window
Close the Computer Management window

Trusting the Domain Certificate

The WEBDAV server is set up to require a secure link; this requires that your computer trusts the certificate authority that issued the server's security certificate - in this case the Windows domain controller.  Computers that are part of the domain, i.e. those supplied by OCTO, already trust the certificate as a consequence of domain membership.  Other computers need to have the domain certificate installed as a 'trusted root'.

First, download the certificate, and store it in any convenient place:

http://album.clinpharm.ox.ac.uk/ClinpharmCA2.cer

Now, install the certificate so that Windows will trust it:

Open the Internet Options applet (either from the Control Panel, or the IE Tools menu)
Select the
Content tab
Click the
Certificates button
In the Certificates window, select the
Trusted Root Certification Authorities tab
If the list contains
ClinPharmCA, expiring 09/09/2014, no more needs to be done
Otherwise, click
Import
Browse to the certificate file you downloaded, and click Next
Select
Place all certificates in the following store (Trusted Root Certification Authorities)
Click
Next, Finish, OK, Close, OK to exit all the windows


Linking My Network Places to the V drive

The following procedure will link to the V drive using WEBDAV.  It is possible to have the computer save your password during this procedure; this is acceptable on an OCTO computer that is protected by using the same login, but must not be done on any other computer.  These instructions are for Windows XP; instructions for Windows 7 will come later.

Open My Network Places (from the desktop or start menu, depending on your setup)
Start the
Add Network Place wizard
On the first screen click
Next
Check that
Choose another network location is selected and click Next
In the address box type:
https://octo.clinpharm.ox.ac.uk/VCDD (N.B. https:)
Click
Next
When the login box appears, type your
OCTO Windows login (you don't need to include the domain)
Change the description if you want, then click
Next and Finish
When the window showing the V drive opens, you will need to
repeat your login


Accessing the V drive after setting up

To access the V drive after setting up, simply open or explore My Network Places, and select the remembered link to the V drive.  If you have not saved your password, you will need to provide your login from time to time.


What about the I drive?

It is possible in principle to access your I drive using the same procedure.  However, this first needs to be set up at the server for you individually.  Please contact Paul if you wish to have this done.
