Network Drive disapear in Explorer (2012R2, Citrix XenApp 7.5)

We have some crazy bevavior on our Windows Server 2012 R2 infrastructur.
SERVERS
+ 3 HP ProLiant DL380 G8 Server with Windows Server 2012 R2, thereof 2 with Hyper-V Role
+ 13 Virtual Windows Server 2012 R2
On those virtual Server running the following roles:
+ 2 Domaincontroller with AD and DNS
+ 1 Exchange Server 2013
+ 1 Server with Citrix XenApp 7.5 Delivery Controller und Studio
+ 2 Server with Citrix XenApp 7.5 Delovery Controller Agent (Worker Server), one is inactiv
+ 1 Server with Citrix XenApp 7.5 NetScaler WebInterface
CLIENTS
+ ca 20 Windows 7 Pro
+ ca 25 Windows 8.1 Pro
ABOUT THE BEHAVIOR:
Users Login to their Citrix session from Intranet or Internet. Connection to their sessions works god and users can work normal. About 2-5 times a day every most of the users have Problems with the Network drives. in Windows Explorer the drives disapear.
about 30 seconds later most of the Network drives are available again. we were connected with some users to watch it an we can see in Explorer that de Network drives disapear one after the other on de left side in the Navigation tree. after that most of the
drives came back and are visible again. normally one drive is missing. not the same drive, every time another one. all Network drives are mounted by GPO Policies (GPP). If this happens a user had to Close his Citrix session and start a new one, until the drives
disapear netx time.
Someone of you ever see somithing like this? we didnt understand the Situation and need some help to find a solution. Thanks to all of you.

Hi,
>>If this happens a user had to Close his Citrix session and start a new one, until the drives disapear netx time.
When the drives disappear, are we able to access the network shares via UNC path? Besides, check event logs to see if some related events were logged. Moreover, if we use anti-virus software, we can try to disable it to have
a check. In addition, for this involves third party product, it's also recommended that we contact vendor support to see if they can provide some suggestions.

Unavailable mapped network drive hangs file explorer

I am using Windows 8.1 Pro (x64) and I have this problem from beginning.
I have mapped two network drives, one is my home NAS and second is shared network storage in our office.
When I open some application which is loading directories (XnView for example) in my computer OR I want open some file in any application
OR, especially, I want to save some new document by "Save as" button (in Notepad, MS Word for example), application hangs for about 30 seconds and I can not work with it. Other applications are working fine during this freeze.
The problem occurs when I am at home and the network storage in office is not available (or I am in the office and home NAS is not available of course), but Windows
doesn't show unavailable drive as disconnected.
When I connect my computer to the office VPN (and both network storages are available) OR I unmap unavailable network drive, everything works perfectly... but it is really not comfortable.
I have tried stop Indexing and disable Windows Defender as I read on some forums but without any solution.
Any hints how to solve this issue?

This isn't one I've seen personally, and I can really test whether this would work, however...
On each of your network drives, try selecting something (doesn't matter what, but probably something small is better), right clicking on the folder and selecting "Always available offline" so your machine maintains a local copy of that information.
My logic being, by doing that on both network drives, each of them contains some information which is available regardless of the resource itself being visible. In this situation Windows will continue to show those network drives as available and accessible,
even if you're no longer connected to either network. Since those folders are available the network drives will also be available, and if you're no connected to the resource itself, Windows will still see that drive as connected, will still be able to list
it, and the apps you're seeing this issue with should no longer have any problems (provided they're not trying to access information on one of those drives that isn't available obviously!).

Network Drive as library folder

I am interested in purchasing a wireless router that will allow me to connect an external USB harddrive and allow it to be shared out as a NAS device. Is it possible/has anyone ever had their iTunes library be a network drive like this? Im hoping to have all my music available via laptop sot hat I can play from my laptop as long as Im on the wireless network.
Anybody ever done this before, and/or have any experiences to share?

Some find it easy to do, others have trouble.
Most important thing is to get drive onto network and available to computer in Windows Explorer. Once you have that done make a folder on drive, call it whatever you want. Now map a drive letter to the folder on the NAS. In case you don't know it is under Tools>Map network drive in Windows Explorer. Fill in the appropriate information.
Then, in iTunes set iTunes library location to the drive you set up. By mapping the drive directly to a folder you only have to tell iTunes the drive letter. Make sure iTunes is set to copy files to library when adding. That way when you add files to the library it will automatically put a copy of the file on the NAS.
Read this about moving library
http://docs.info.apple.com/article.html?artnum=301748
A final caution is to make sure the NAS is available to computer before starting iTunes to prevent library sync problems. I did this by making a shortcut on desktop that opens a Windows Explorer window showing NAS. What this does is wakes the drive and ensures connection is ready. If you don't do this iTunes will revert to using the iTunes music folder in My Documents. You will then have to consolidate library after closing iTunes, making drive ready, then starting iTunes again.

Windows 8.1 windows explorer does not connect to network drives

I have a network drive (SAN) on my local network which everytime I re-install windows I cannot connect to it anymore.
Last time I fixed this issue it was just a single checkbox(or radio button) but I cannot remember where it was and what was it called.
I am getting error
"Error Code: 0x800704b3
The network path was either typed incorrectly, does not exists. or the network provider is not
currently available. Please try retyping the path or contact your network administrator."
Which none of them are true and by the way, I am the network administrator in my home network and sorry that I cannot contact myself (ain't sometimes Microsoft error messages as stupid as their developers?)
1- I can connect to internet and browse web and receive mail too. so my network connection is working perfectly.
2- I can ping my device (using both its IP and name). I can see an IP assigned to my device.
3- I can browse my device and even access its management service using firefox (I don't have internet explorer because I removed it)
4- I have File and printer sharing for microsoft network (in ethernet properties) installed and activated too.
5- windows installation is new so nothing is changed in it.
6- my firewall is not blocking the access to device either (If I disable it still cannot see the network drive)
7- Network and sharing center is empty!
8- In IPv4 advanced properties Netbios over TCP/IP is enabled too (which I think that was what fixed it last time)
9- there is no error event is listed in event viewer.
What is this problem that I have to fix every single time I install windows 8.1 I have to fix?

Hi Bob,
It seems like your network is working properly. So If you make sure your network path is correct, let us check other settings for mapping network drives.
Check if the issue persists under safe mode and make sure that “TCP/IP NetBIOS Helper” in service.mcs is running.
Make sure your computer name is unique and using NetBIOS over TCP/IP.
The computer name could be either a Netbios name or a DNS name. so if one doesn’t work check the other one.
You also could try the net use command, to see if it might return additional infomation

Windows explorer keeps computing items after accessing a mapped network drive

Our organization has decided to upgrade to windows 7 but we are running into a problem with windows explorer green progress bar hanging after accessing a mapped network drive. When you try to go back to computer or access the control panel after going
3 or more folders deep into the mapped drive, windows explorer just keeps searching.
When you expand the arrow in the address bar it states that it is computing items and never stops.
The only way around this is to right click on libraries and select reset back to defaults and everything is back to normal.
We are deploying this image of windows 7 to over a 1000 computers and we cannot have this problem lingering, does anyone have a solution to resolve this issue. This does not happen in Windows XP.
We have tried to turn off windows search and remote differential compression and this does work but the problem is that you lose all search capabilities in windows. So windows search needs to be enabled. We also tried to adjust the MTU, change GP settings,
and nothing seems to work except to turn windows search off or reset libraries back to default.
We also did some research online and there are so many people experiencing the same problem, with no resolution expect they have to go back to Windows XP. That is not an option for us.
Please help us we would really greatly appreciate it.

Hi,
The issue could be related to searching and indexing feature in Windows 7. I suggest rebuilding the indexing files.
Click Start -> Type
indexing options in the search box -> Advanced -> Index Settings tab-> Rebuild buttion.
For more information, you can refer to:
http://windows.microsoft.com/en-us/windows7/Change-advanced-indexing-options
If the issue persists, you can perform the following troubleshooting steps.
1. Go to update your network adapter drivers and BIOS from manufacture's site manually.
2. If any router is involved, please update the firmware.
3. Perform a System File Checker.

Windows Explorer: access to network drive is denied

Hello
When I open Windows explorer and type in the address bar a location that points to a drive (local or networkdrive), I get the error message: access to drive is denied.
The network drives points to an DFS location. The personal user drive is assigned through the users account name in Active Directory, the other drives are mapped with an logonscript.
When I browse to the drives (local or network) with command-prompt, there is no problem. The users have sufficient rights to their folder.
Also I have tried to remap the drive manually with net use, but the problem still exists.
Anyone an idea?
Thanks for the help.

Hi,
Could you access the local drive directly from Windows Explorer which show every your local drive?
Like Forest suggeation, please get the enough permission of these drive firstly.
If the issue still persists, please try this(Note: backup the registry entry when you modify it):
1. start -> run;
2. type regedit to open registry;
3. go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoint2\;
4 now you can see keys like
{4bdd4abb-fe4b-11d5-8453-806d6172696f}
{4bdd4abe-fe4b-11d5-8453-806d6172696f}
5. if you see any sub folder in it like Shell;
6. delete Shell folder;
7. confirm the issue.

Cannot quit Visual FoxPro (Windows Terminal Server 2008 + Citrix XenApp 5 + VMWare vCenter 5.1)

Hi everybody:
This is not the typical question about this error, because the problem here is not about how to quit (CLEAR EVENTS then QUIT). The really and weird problem is that our application do no execute the error trapping routines (Try/Catch and ON ERROR) and tries
to directly Quit.
I have never seen something like this before, error trapping routines not executed.
I try to explain the problem better:
- The user click on the Citrix icon of our App
- Citrix shows the executed processes (establishing connection, applying user config, loading profile, etc)
- The Application (VFP 9 SP2) is started and in any moment, while loading, occurs an error that is not handled by error handlers, and it executes a "kind" of a Quit command, that we detect because have a ON SHUTDOWN to catch it, then the App shut
down and the user must click the Citrix icon and start all over again, up to 7 times, when the App really load and work.
- I think that it is useful to make clear that no QUIT command is really causing this, just the behaviour of the QUIT when an error occurs, but just while loading. If the App get completely loeaded, then everything works as expected
Infraestructure:
- Windows Terminal Server 2008 + Citrix XenApp 5 + VMWare vCenter 5.1
- There are up to 50 concurrent users max in every virtualized server
- More than 10 GB of free disk space / Up to 4 GB ram
- RAM Memory is never used to the max
- CPU (Intel Xeon) is never used to the max (up to 90% in some cases)
- Data (DBFs for temporal work) ar on local drive, not over network (to avoid network known problems with smb2-3)
- There are connection to a Oracle 11 database for permanently storing the data
About the errors:
- They are not always the same or in the same place. In example, in one execution could fail the query of SET("Printer",2), in other execution could fail a SET PROCEDURE TO xxx ADDITIVE (sometimes already loaded), in other could fail a "DO
WHILE .T." in a init event.... completely crazy, and in all cases the errors are not thrown, not a single error code, the App just try to quit, as if ALT+F4 where pressed.
- All this does not happen allways to everyone, but happens many times in the day to many many users as to be worried
- The same user can have this error many times a day, but not allways
- Some of the problems started when migrating to Windows Terminal Server 2008, but didn't notice nothing special in the beginning, but a year later (last 2014) problems tend to go worse
Tried solutions:
- For the "SET PROCEDURE TO xxx ADDITIVE" error, a "IF xxx $ SET('PROCEDURE')" check was added
- The "SET('Printer',2)" check was moved out of initialization code, so it executes when user want to print the first time. In this case was neccesary to talk with IT guys to map a default printer after the App runs, and not in background, as it
was.
- Other checks and modifications was made to minimize posibility of errors
- Adding a timeout of 5 secs in the start of the program, to force a wait
- Restart of virtual servers (not the phisical) every 3 weeks
What I suspect:
- Some Microsoft optimization (memory?, process execution?) in WTS-2008 may interfere?
- Some VMWare memory management may interfere with WTS-2008?
- Some Citrix management may interfere with both?
- Server degradation because of day to day use
Results until now:
- Apparently, adding the timeout to force 5 secs delay and the restart of the server have made a notable enhancement in App start and running
with far fewer
errors
Has
this happened to anyone?
Thanks! o_O
Fernando D. Bozzo / Madrid (Spain)

I never had this type of problems, but somewhat similar start up problems. I'd say it indicates resource problems. Low RAM can cause many unpredictable things. In my case loading much data at the begin of an application caused out of memory errors, which
were reported and logged normally, though.
I made a small tool using Windows API functions GetPerformanceInfo and GetProcessMemoryInfo, you'll find declaration and usage like usual at the News2News site. It's a bit lengthy and cluttered, but pretty much what you find there anyway, so I'll not post
my utility code.
I could quite clearly see how many users degraded available memory per session and at some time no further instance of the application was possible on the server. In my case RDP was used to start the app, Citrix will be quite the same, in the end the application
runs on some server and users see the remote running application.

Oracle client with Citrix Xenapp 64 bit

Hi,
I have below queries :
1) Can we install Oracle 9i client 32 bit on Citrix Xenapp 64 bit machine ?
2) Can we install Oracle 9i client 64 bit on Citrix Xenapp 64 bit machine ?
3) Can we install Oracle 11g client 32 bit on Citrix Xenapp 64 bit machine ?
4) Can we install Oracle 11g client 64 bit on Citrix Xenapp 64 bit machine ?

Queries do not make much sense.
Oracle does not provide client db drivers for a hypervisor or vritual machine system software. It provides it for the operating system used.
Oracle provide client drivers, 32bit and/or 64bit, for a number of operating systems and operating system versions. Does Oracle provide drivers for Windows XP? Yes. For Windows Vista? Yes. For Windows 7? Yes.
See Instant Client Downloads.
Whether such a driver works on a Windows o/s that is running in a virtualised container, and can provide database connectivity, depends on the nature of that container's support for the underlying operating system, and the configuration of that container ito of network connectivity to the real world.
Oh yes - using Oracle 9i in any shape or form also does not make sense. It is a product discontinued years ago.

Adobe Reader X (10.1.1) Visual C++ Runtime error - Citrix XenApp 4.5

Error:
Microsoft Visual C++ Runtime Library
Runtime Error!
Program: C:\Program Files\Adobe\Reader 10.0\Reader\AcroRd32.exe
I work for a large government agency, and we are experiencing the above error, but we have the added complexity of Citrix (XenApp 4.5). Most of our servers run Server 2003 SP2 Enterprise.
When you log into the server's console, a PDF from a network location launches fine, however a Softgrid package which contains a link the PDF produces the error (unless you have elevated domain privileges - and then it works fine).
Using Citrix to launch the PDF via the Softgrid package or the network drive sometimes works, but randomly produces the error. Our security team will now allow us to disable Protected Mode (from our last test, disabling Protected Mode resolved the issue).
A Procmon log of a failure to launch shows AcroRd32.exe producing an Insufficient Resources error to an IPC share on all our DFS Namspace servers. After that Reader seems to terminate.

Hi,
Can you please let me know the following information:
1) Is the issue exist for previous versions of Reader as well (like Reader X, Reader 9)
2) Does your organization also use XenApp 5 or XenApp6? If yes, can you please try to reproduce the issue for the clients of those servers.
3) Please try out the following :
-- Launch Reader10.1, Goto Edit->Preferences -> General . Un-select the option 'Enable Protected Mode at startup' and close Reader.
-- Open the PDF file which was throwing Visual Runtime error and see if the error still persists.
-- After the observation please launch Reader again and goto Edit->Preferences -> General and now select 'Enable Protected Mode at Startup' and close Reader.
(Reader should always be kept at Protected Mode as it is much more secured)
Thanks,

the xenapp 6.5 command would be "D:\test.bat". now it's working fine..but we don't want to use this method..if any other solution or ideas would be greatful for us...
Kindly help..
Thanks in advance, Maheswaran

From an App-V perspective: is the app published to the users (log in as a user and run

Citrix XenApp Unable to Open Published Applications. Via UAG Trunk

Good Morning,
I'm trying to publish XenApp through a UAG trunk. When I click in the XenApp icon I am presented with the Citrix login page and am able to log in. However, if I try to open any application I am prompted to either open or save the ICA file and on clicking
open I always get the following message, "Unable to launch your application. Contact your helpdesk with the following information: Cannot connect to XenApp server. There is no Citrix XenApp server configured on the specified address." If I log in
to the UAG server I can connect to the Citrix server and run all applications without error. If I save the ICA file the contents are as expected and the correct server is listed.
Forefront UAG is running a two node NLB array with SP4 and Citrix is published via an F5 load balancer.
Any ideas out there?
Thanks.

hi patrick,
this problem is not solvable on the serverside since this is a desktop integration problem. since you want to use excel as your editor you have to use excel's client side software.
oracle drive purely addresses desktop integration and is not meant to be a server side component. it is a webdav client and for that only ensures that the communication between the client and the portal server has as much useful functionality as possible.
the only other option that i see is downloading the document to the client, update it and copy it back up to the portal server, which is cumbersome.
all webdav clients are client side software that is either shipped with the OS (MS webfolders) or needs to be installed on the client (oracle drive).
you could check if there is software availble that is an excel plug-in for internet explorer which at the same time talks webdav to portal. not sure if this exists ?

christian

Creating a folder alias on a shared network drive

Hi,
I have a folder that is housed on my computer that I would like an alias of on my company's shared network drive. I will have access to the shared network drive from my home computer either through Citrix or a VPN, so I would like the alias on that drive so that it will reflect any changes I make to the files within either from my work or from my home computer. My question therefore is, how do I create an alias of a folder on a shared network drive? I tried creating an alias on my local drive and then dragging it to the shared network drive, but that just copied the folder and removed the alias.
Any help would be greatly appreciated!

Nevermind. I must have copied over the original folder the first time instead of the alias, as a simple drag and drop of an alias folder just worked fine for me.

Error saving Project 2010 files to network drive - doesn't see network drive

ANSWERED (11 April 2014):
So it seems the resolution to this is to simply create a new share with a different name. I used the existing folder (to retain NTFS permissions) and just select to Add a new Share (applying the same Share permissions as the non working Shares).
Deploying this new Share via Group Policy as a test resulted in staff being able to open files from Windows Search, save files through MS Project and the Share being accessible through browsing SMB.
All problems resolved by using a new share name for the existing folder. Seems to be a corruption in the namespace.
Note: I had previously deleted the share and recreated it. I had removed all NTFS permissions and readded (through both the GUI and icacls). This didn't make a difference.
Only changing the name of the share fixed the problem.
Original Question
Already
posted here... but Microsoft Support has not responded.
It seems some staff on some computers are having problems saving MS Project files to the network. This is only since an upgrade to SBS2011 (from SBS2003). The only difference now, is that network drives are mapped via group policy rather than a 'net
use' script.
This is affecting users on Windows 7 and Windows Server 2008 R2, with either MS Project 2007 or 2010. The users have full change access to the folders and can create new files and modifying existing files, just not a MS Project file. Other file tyes, e.g
Word .docx, Excel .xlsx, Adobe .pdf files, all work fine. These files can be opened, edited and saved normally without problem.
To replicate this:
The user opens an existing file or creates a new file on the network folder (either through Windows Explorer or MS Project). They then click File > Save in MS Project and receive the following error (see pic below):
An interesting symptom of this is that if you select File > Save As in MS Project, the Sae As dialog box doesn't remeber the path location of the network drive. MS Project instead prompts to save the file in the local users documents folder (see pic below):
If they browse back to the original folder where the file was saved and choose to save it there, they are of course, prompted to overwrite the existing file and they can save the file. But the same thing happens every time they open the file.
It seems the problem is that Project isn't seeing the path of the file or that the network drive is attached.
If a user closes the file without saving it, they are prompted to save the file and the prompt shows the drive path:
Do you want to save changes to "N:\... Projects\Active Projects\CC...\F4 Project Plan File\004 Programme\test project file.mpp"?
But choosing to save the file gives them the same result as Save As, they are prompted for a new location as if the original file location doesn't exist.
I have disconnected the mapped drive and connected it again using net use but get the same error.
I have reinstalled MS Project 201, installed Project 2010 SP2 and installed Windows updates and it does the same thing, exactly the same symptoms.
Further, if the user opens a file from the network drive, the file shows in the Project recent files list. If they try to open the file from the recent files list in project they get the following error:
"Project cannot open the file.
-Check that the file name and path are correct.
-Check that the file format is recognized by Project.
Project files saved in a version earlier than Microsoft Project 98 can't be opened...."
This is a test file that I created on the user's computer and network drive, This is being opened with the same version it was created in. If I browse to the folder in Windows Explorer I can open the file. Of course, I then can't save the file (I still get
the original error). I'm logged on with Domain Admin privileges.
I've checked these links from other threads (neither apply to my scenario):
http://support.microsoft.com/kb/983458/en-us|
http://social.technet.microsoft.com/Forums/en-US/excel/thread/2eeea140-7e6c-4cb9-a89b-06d2102bd9f7/
I've downloaded my TechNet version of he software and installed it with Sp2 and Windows updates and it does the same thing. This also happens on the Remote Desktop server (Server 2008 R2) using MS Project 2007.

Case 1
This error message appears when the document is open on two or more computers that are running different operating platforms. For example,
if the document is open on a Macintosh computer and you open it on a second computer running Windows or Windows NT, the error occurs when either user tries to save the document.
This problem stems from a difference between the ways Macintosh OLE and Windows OLE open files. As a result, you cannot save a file on two different operating platforms at the same time.
Case 2
This error occurs in Word 97 for Windows if you save to a MAPROOT type network drive connection on a NetWare server where spaces exist in
the file or folder name.
Case 3
This problem may occur if an anti-virus program running on a network has the ability to scan for macro viruses in documents in shared network
folders.
For example, if you have the following:
a shared folder on a network server
-and-
an anti-virus program is running on the network server that is set to monitor the shared folder,
when you attempt to save a document (across the network) to the shared folder, the anti-virus checker may cause the error to occur.
Case 4
This problem may occur on Novell networks when the AutoRecover files path is either blank or set to a network drive.
According each, please try the following workaround:
WORKAROUND
To work around this problem, use one of the following methods appropriate to your situation.
Case 1
Method 1:
Move the document to your local hard disk for editing. Move it back to the server after you finish.
Method 2:
Save a copy of the
file with a different
file name, and work on the copy, either on your hard disk or on the server.
Case 3
Method 1:
Move the document to your local hard disk for editing. Move it back to the server after you finish.
Method 2:
Do not use spaces in the directory or document names.
Method 3:
Do not use MAPROOT-drive connections. Map your drive connections to the volume-level only.
Case 4
Turn off the anti-virus protection on the network server and then try to
save the document. Contact your anti-virus protection software company for additional details and/or updates to their programs.
Case 5
Set the AutoRecover files path to your local drive. To change the AutoRecover path, use the following steps:
1.
On the Tools menu, click Options.
2.
On the File Locations tab, select AutoRecover files and then click Modify.
3.
Change the Modify Location dialog box to a
folder on your local drive and then click OK.
4.
Click OK to close the Options dialog box.
Hope that helps.

Enable Recycle Bin on mapped network drives

A few years ago I discovered how redirected user profile folders in Windows get Recycle Bin protection, even when the folders are redirected to a network location. This was a huge find for me, and I used this feature to add Recycle Bin coverage to some of
my mapped network drives. I shared this information on another forum here:
http://forums.mydigitallife.info/threads/16974-Tip-Network-Recycle-bin
Today I figured out a better way to achieve the same goal that doesn't rely on user profile folder redirection, and am sharing that information for other users to try out. You might want to take a look at these forum topics for additional information:

The standard disclaimer applies - this might break stuff. I've only tested in Windows 8, and my testing is limited. Try this at your own risk.
This is what I've learned (or think I've learned - I might be wrong):
Windows Vista and later store the configuration settings for the Recycle Bin for redirected user profile folders in this registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\BitBucket\KnownFolder
Under this key are separate keys for each redirected folder that is protected by the Recycle Bin. The keys contain the configuration information for each protected folder, and are named to match the GUIDs for "Known Folders." A list of the Known
Folder to GUID mappings is available in one of the links above.
The registry also contains a list of "known folders" at this location: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions
So, I reasoned that if I could create my own custom "known folder," I could add that to the list of folders that were protected by the Recycle Bin and protect any mapped network drive I wanted. So I looked at the list of existing "known folders"
and created a key that was similar to the Documents key. I then fiddled with the values in the key until I narrowed it down to the minimum number needed to make the recycle bin work.
This .reg file will protect a mapped X: drive with a ~50GB recycle bin. You should modify the file to fit your needs:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions\{9147E464-33A6-48E2-A3C9-361EFD417DEF}]
"RelativePath"="X:\\"
"Category"=dword:00000004
"Name"="XDrive"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\BitBucket\KnownFolder\{9147E464-33A6-48E2-A3C9-361EFD417DEF}]
"MaxCapacity"=dword:0000c7eb
"NukeOnDelete"=dword:00000000
A few things of note:
The GUID in the above .reg file {9147E464-33A6-48E2-A3C9-361EFD417DEF} came from this PowerShell command: "{"+[guid]::NewGUID().ToString().ToUpper()+"}"
Each "known folder"/Recycle Bin combination requires a unique GUID. If you don't want to use PowerShell to generate a GUID, you can use an online GUID generator.
I don't know what the "Category" value does, but the key I copied had it set to 4, and that works, so I didn't test any other values.
The "Name" value is required, but is not the name that will be shown if you right-click on the Recycle Bin and select properties. (At least not in my environment.) In my environment, the name that is shown is the name of the network drive.
Making this change adds a "Location" tab to the properties page of your mapped network drives. I suspect this could be removed by changing the "Category" value, but didn't bother to find out.
I only tested with mapped network drives. I suspect this would work with UNC paths as well, but I didn't bother testing.
I hope you're as excited to find this as I was to figure it out. Let me know if this works for you. I now plan to deploy the registry keys with Group Policy Preferences and will update this forum post with any information I discover.
Best regards
--Russel
Update: I am now using Group Policy Preferences to deploy the needed registry keys, and all my mapped network drives are now protected by the recycle bin.
Update 2: I have tested now with UNC paths, and this works fine. I still use mapped network drives, but if your environment requires UNC paths instead, you can use them. Note however that if you have a mapped network drive that points to a UNC path, and
you protect the UNC path with a registry change, if a user deletes a file from the mapped network drive that points to that UNC path, the file will be permanently deleted. See below for more details.

FANTASTIC work Russel !
This is extremely helpful.
I've turned your work into a Bat Script that will automatically make the reg file.
It creates a unique guid each time it is run, so no worries on overlaps.
Just copy and paste the following into notepad
and save it as "Network Recycling Bin - auto make registry file.bat"
echo off

Firefox sees that (at least local or network dive located) .bat files are text and renders them as such. To download it as a .bat file, use save page as, (or Control-S) change "text file" to "all files" and type .bat onto the end of the filename, then hit save. Not ideal I know, but better than nothing.
