This page described migration of data from Novell Netware server cluster to Distributed File System server cluster.  As of Monday, January 31, 2011, all content formerly in these two systems can be found on middfiles. 
* We have switched campus wide to the new DFS System (we refer to all the new servers as middfiles).
 
* The default quota was increased from 200MBs on Tigercat to 3GB on middfiles.
 
* What used to be called TIGERCAT (the U drive) is now the \home\ folder on Middfiles.
 
* What used to be called SNOWLEOPARD (the O drive) is now the \orgs\ folder on Middfiles.
 
* What used to be called OCELOT (the N drive) is now also the \orgs\ folder on Middfiles.

=== On a PC ===
 
Map a network drive to server '''\\middlebury.edu\middfiles'''. Use the same midd\username credentials as we used before.
 
  
If you want to connect directly to a specific server such as Classes or Tigercat, just specify the appropriate subdirectory:
+
<br>[[Category:Mac|Mac]]
* \\middlebury.edu\middfiles\home (Home folder or Tigercat)
 
 
 
=== On a Mac ===
 
The server address is now '''smb://middfiles.middlebury.edu/middfiles/'''. If you want to connect straight to Home (Tigercat) or another area, just specify the folder like so: smb://middfiles.middlebury.edu/middfiles/home or smb://middfiles.middlebury.edu/middfiles/orgs/, etc. (See above for the folder names corresponding to each server.)
 
 
 
See possible issues, below.
 
 
 
=== On Linux  ===
 
 
 
Generally not compatible. See the [https://mediawiki.middlebury.edu/wiki/LIS/Ubuntu#Connecting_to_File_Servers Ubuntu page] for a possible workaround.
 
 
 
=== Alternative methods ===
 
Users can still use '''Netstorage''' to access the server by going to this address: http://go.middlebury.edu/files
 
Note: Netstorage throws an error when you try to download a file using MS Internet Explorer 7.
 
 
 
It is possible to use FTP to access the new file servers. The name of the ftp server is middfiles.middlebury.edu
 
 
 
FTP is not recommended as it sends your password in plain text. If a malicious person is [http://en.wikipedia.org/wiki/Packet_analyzer en.wikipedia.org/wiki/Packet_analyzer sniffing your network connection] they can also copy every file that you access through FTP. Therefore, it is recommended to use the secure web access to your files: http://go.middlebury.edu/middfiles or a VPN connection in conjuction with mapping a network drive or using the Finder =&gt; Go =&gt; Connect to Server.
 
 
 
== Public Computers  ==
 
 
 
The Novell&nbsp;Client has been removed from all public computers. If you find a computer with the Novell client, please leave it turned on, and give the Helpdesk the name of the computer [https://mediawiki.middlebury.edu/wiki/LIS/Image:Get_computer_name_from_login_screen.jpg Get_computer_name_from_login_screen.jpg]
 
 
 
== Issues Encountered with DFS  ==
 
 
 
=== Mac OS X 10.6 - Snowleopard should now work with DFS via SMB/CIFS ===
 
 
 
*Can still use FTP and go/files.
 
 
 
=== Saving a file on a file server causes the computer to crash  ===
 
 
 
*Description: Trying to save a file to [NAME A FOLDER] under Orgs [or HOME, or some other folder on a mapped drive], but each time saving the document, the computer crashes (blue screen of death).
 
*Most likely cause: Novell is still on the computer
 
*Solution: Remove Novell
 
 
 
=== Drive mappings for Middfiles either don't appear or are intermittent  ===
 
 
 
*Description: Drive mappings for Middfiles either don't appear or are intermittent
 
*'''Note:''' This applies ONLY&nbsp;to Windows computers that are attached to the middlebury.edu domain (college-owned)!
 
*Cause: Group policy is not updated properly on the computer.
 
*Solution: Start - Run - type "gpupdate /force" - OK - follow prompts, including for reboot.
 
 
 
=== Microsoft Office applications are slow or freeze  ===
 
 
 
*Description: Outlook is slow when attaching files, Excel, Word are slow or freeze when opening or saving files (e.g. File =&gt; Open or File =&gt; Save.)
 
*Most likely cause: This can happen if there are disconnected network drives (in My Computer) pointing to novell servers (tigercat, ocelot or snowleopard) that aren't properly disconnected.
 
*Solution: <br>Open My Computer, click on Tools =&gt; Disconnect Network Drives, then select any drives pointing to tigercat, ocelot or snowleopard, and click OK.
 
 
 
=== Open File Security Warning when opening .EXE (or other files) on middfiles<br> ===
 
 
 
*Description: Open File Security Warning when opening .EXE (or other files) on middfiles
 
*Cause: This is a security feature of Microsoft Windows.
 
*Solution: Add file://*.middlebury.edu to the list of trusted sites in Internet Explorer. Start =&gt; Control Panel =&gt; Internet Options =&gt; Security =&gt; Trusted Sites =&gt; Sites, uncheck the checkbox that requires https. Add file://*.middlebury.edu
 
 
 
=== Computer crash with Blue Screen or error message NWGINA.DLL Failed to load  ===
 
 
 
Description: Your computer crashes and displays a blue screen of death with the error message "NWGINA.DLL Failed to load". The error message may also be: "The Logon User Interface DLL NWGINA.DLL failed to load. Contact your System Administrator to replace the DLL, or restore the original DLL."
 
 
 
Solution: The fix seems to be a Registry Edit (see below). I am sending this out just in-case this is a wider issue. Please make sure if you need to use this fix that the Help Desk performs ANY Registry edit.
 
 
 
#Restart the computer, and press F8, select Safe mode without Networking.
 
#Run regedit and go to '''HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon'''
 
#Change GinaDLL from NWGINA.DLL to MSGINA.DLL, then reboot.
 
#You should be able to logon and uninstall/reinstall the NetWare client.
 
#See also TID10052901 (http://support.novell.com/cgi-bin/search/searchtid.cgi?/10052901.htm).
 
 
 
=== Troubleshooting Classes and&nbsp;Dropbox folder issues ===
 
 
 
See [[Troubleshooting_Classes_and_Dropbox_Folder_Issues|Troubleshooting_Classes_and_Dropbox_Folder_Issues]]
 
 
 
=== Using Mac OS X to connect to middfiles and all folders/aliases appear grayed out  ===
 
 
 
*Description: You are using Mac OS X and the Finder to connect to middfiles. You can connect just fine, however all the folders or aliases are grayed out, or nothing happens when you click on them.
 
*Cause #1: You may be using the wrong server. Solution #1: Do NOT use smb://middlebury.edu/middfiles to access middfiles on a Mac. Use smb://middfiles.middlebury.edu/middfiles instead.
 
*Cause #2 and solution: Most of the "folders" that you see on middfiles are actually shortcuts (or aliases). When your Mac OS X computer opens a folder with any number of aliases, it starts analyzing them and tries to determine where they lead. In folders with lots of aliases (or when the server is under greater load), this process may take some time during which the aliases are grayed out and nothing happens when you click on them. Simply wait a little longer and the aliases/folder will become available. It also helps if you are viewing the folder as a list if icons in the Finder. You can choose this option under the "View" menu (top left corner).
 
 
 
== Technical Details of DFS ==
 
 
 
* A group policy update runs whenever an LIS staff person logs in to a PC computer.
 
* It might take a reboot or two for the group policy update to be applied.
 
** If a customer complains that they haven't been prompted to remove the novell client, have them reboot. You can also force the group policy update by clicking Start =&gt; Run =&gt; gpupdate /force
 
* When the update is applied, after login, after 1 min, a window appears asking the user to remove the Novell Client
 
* A reboot is required after removing the Novell Client
 
* After the reboot, there is no more Novell client and the file servers are mapped automatically by a script (it's invisible).
 
** Tigercat (our home drive) has been replaced with \\midd\middfiles\home (your new home drive remains mapped at U:\)
 
** Snowleopard (the "O" drive) has been replaced with \\midd\middfiles\orgs (still mapped at O:\)
 
* If a user was not using the Novell client, they will need to disconnect their old network drives and map the new ones (they can reuse the drive letters):
 
** Open My Computer, right-click on tigercat, disconnect
 
** Tools =&gt; Map Network Drive =&gt; Drive letter: U =&gt; Server is \\midd\middfiles\home
 
** Disconnect snowleopard. Snowleopard is replaced with \\midd\middfiles\orgs
 
* NetStorage (go/files) has been replaced with a product called HTTPCommander (seems to work fine and uploading is faster, but it did freeze when I tried searching). Can be accessed at http://go.middlebury.edu/files<br>
