I'm replying to myself here because I forgot a couple of extra items at
When a global drive is mounted, and the user logs on. If you open an
Explorer file browser the drive will show up as a "Disconnected Network
Drive". You are not able to change the label of this drive because the
Explorer file browser does not consider that drive as yours, under your
explorer shell mount table. This is not a problem however because the
drive operates as normal. It's just ugly for the user to see the
"disconnected" part. We get questions from our users about this from time
to time. Others just don't care.
Related and ugly messy stuff related to the global drive...
If you have roaming profiles for your users, and you are using a global
drive, then you need to figure out what to do about this registry key...
This is the users explorer shell mount table. Actually the disconnected
drive is listed there in the mount table, but the Explorer lists it
(recreates it) at every logon as a different GUID and so we can't do
anything with that since we have no idea which GUID is the proper one to
change (if we want to set a drive label). As the user logs on and off over
time this table will normally be managed by the shell for you. However, if
you are using global drives, the explorer shell will not ever remove those
newly created GUIDs and it will begin to fill up over time with registry
entries. This is BAD.
At our site, since we have the luxury of being fully in control the users
desktop experience, I decided to completely erase this folder at every user
logon, using a user logon script. Our user logon script runs before the
explorer shell starts, so there is no interference with explorer while
performing this deletion. Since the "MountPoints2" folder is the root of a
tree of registry keys, you need to delete that folder and everything under it.
I found the "MountPoints2" key quite by accident last year when doing
research on why a drive label can't be set for "Disconnected Drives". It
was then that I observed that it filled up over time.
Once the user is logged on, if you create and other driver mounts to AFS
for the user in a user logon script, then you CAN set the label
name. Here's the code I use for example...
Note: this is the forced way by direct registry manipulation. Microsoft
frowns on this because you aren't supposed to go changing things behind the
Explorers back, and besides, according to Microsoft you shouldn't change
anything under their "Microsoft" key anyway.
Drive mount in user logon script: net use u: \\afs\%username%
ntregedt AddValue HKEY_CURRENT_USER
"_LabelFromReg" REG_SZ "AFS Unix Drive"
Here's the more appropriate programatic way (using vb scripting):
Set oShell = CreateObject("Shell.Application")
mDrive = "U:"
oShell.NameSpace(mDrive).Self.Name = "AFS Unix Drive"
If you've understood this, then you must be sober, so enjoy,
