Cannot Access Shared Folders on WinXP Host / WinXP Guest

Would be nice if you could provide more information. What does that mean can't create or access shared folders anymore? How do you create shared folders, using the GUI (VM settings) or during runtime from the menu? Are the 'VirtualBox Shared Folders' shown in the Folders list when you do 'Map network drive ...' and press Browse in the next dialog?

Hi Frank... ;-)

Well...

1) the old version (1.6.3) of G.A. (Guest Additions) don't work with 1.6.4. The Shared Folders cannot connect into Host;

2) So What I Did? I uninstall old version of G.A. and install new 1.6.4 G.A. - Shared Folders isn't present on "Map Network Drive..." and "VirtualBox Shared Folders" too;

3) Trying to access shared folder through Windows Explorer, like "\\vboxsvc\public" didn't work too;

4) After all what I explain above, I tried to uninstall and install G.A., changing the ethernet model and a lot of combos but have no success.

Ah! I tried to create/access Shared Folders through Command Line and GUI.

* about 1.6.3: after downgrade to 1.6.3, the Shared Folders is there...

If you need any help and I can help, let me know... ;-)

Best regards,

WCarvalho

I'm just curious: Where did you get a 1.6.3 version from? This must be some developer release then.

Furthermore, doing a "\\vboxsvc\public" won't work. A "\\vboxsrv\public" or "\\vboxsvr\public" will do it. So please go to the cmd line and type "net use s: \\vboxsrv\public".

If this doesn't help, please re-install the 1.6.4 G.A using "/l" (for logging into install.log) as command line parameter when executing the setup and attach the log as a file here.

Well... pentagonik

Have no success...

The install.log has been attached...

about 1.6.3: I received it version to do some tests after help to solve the issue: BSOD 8E on compiling delphi/visual C++ sources from shared folders.

Let's solve it ones... ;-)

WCarvalho.

from Guest Additions v1.6.4 (host/guest WinXP)

Which detailed version was that (the 5 digits are important as they name our internal SVN revision)...

With which user you are working? Does it have admin rights?

1. Open the registry (type "regedit.exe" into the command line).
2. Go to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services".
3. Verify, that the keys "VBoxGuest", "VBoxSF" and "VBoxService" are there.
4. Export each of the three keys above by right clicking on them and click
   on "Export". Upload the files to our board / bugtracker later!
5. Open the service manager (type "services.msc" into the command line).
6. Look up the entry "VBoxService". Is it started? What's its status?
7. With the Explorer go to "<Windows-Directory>\system32".
8. Look up the file versions (right click on the file, 
   "Properties" -> "Version" -> "Product Version" in item name table below) 
   of these files:
   
   <Windows-Directory>\system32\VBoxMRXNP.dll
   <Windows-Directory>\system32\VBoxService.exe
   <Windows-Directory>\system32\drivers\VBoxSF.dll
   
9. Include these file versions into your next report.

Hi pentagonik ... :-)

0) My rights for each machine is Administrator; 1) OK; 2) OK; 3) There's no one of that keys; 4) Cannot export because 3); 5) OK; 6) There's no VBoxService on Services List or on Registry; 7) OK; 8) There's no one of that files; 9) Cannot report because 8).

PS: I tried to install on 3 machines (Host/Guest WinXP), with Administrator Rights... two of them are Brazilian Portuguese SP3 and another one US SP3.

PS2: Have the .MSI all files and policies to install that missing files on right place and registry keys?

PS3: I'd a deep scan and haven't found it files: <Windows-Directory>\system32\VBoxMRXNP.dll <Windows-Directory>\system32\VBoxService.exe (VBoxSVC.exe ?) <Windows-Directory>\system32\drivers\VBoxSF.dll

Next step? ;-)

Hm, I forgot to mention that you have to do all the 9 steps above in your VM, not on your host :-) Could you try again, please?

Hello!

I have same problem with VB v1.6.4. My host is WinXP, and VM too. My VM not contain VBoxService.exe.

Hello pentagonik ;-)

0) Again, :-) my rights for the machine is Administrator; 1) OK; 2) OK; 3) OK, is there!; 4) OK! Exported and uploaded; 5) OK; 6) Is there! status: RUNNING; start: AUTOMATIC; 7) OK; 8) Is there! (except VBoxSF.DLL - I think it must be ".sys". misstype?)

- VBoxMRXNP.DLL is v1.6.4.33808

- VBoxService.exe is v1.6.4.33808

- VBoxSF.sys is v1.6.4.33808 (have .SYS - not .DLL)

9) Report done! (on guest) :-)

@szombatha: Please install the Guest Additions in your VM again; this time using the command line: "VBoxGuestAdditions /l". After the installation you'll find a "install.log" in the installation directory (usually in C:\Program Files\Sun\xVM VirtualBox Guest Additions\). Please post this log here then.

@WCarvalho: Thanks for the information. Yes, VBoxSF.sys is correct, not VBoxSF.dll. This still doesn't work? In addition, please do the following:

1. Go to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control".
2. Export the key "NetworkProvider" (like in step 4). Upload the files to our board / bugtracker later!

ready on! ;-)

Uploaded!

@WCarvalho: Seems all okay to me. So to provide me more information about your problem, please send me an e-mail to pentagonik at sun dot com. I'll then send you a debug version of the Shared Folders.

Some users report that installing the Windows guest additions a second time solves the problem.

I still cannot reproduce the problem here; nevertheless, I'm on it with the support of WCarvalho.

Replying to WCarvalho:

Hi!!! I can't create or access Shared Folders anymore... I tried it on several ways, installing and uninstalling the Guest Additions... changing the Ethernet model... reinstalling the Guest Additions... After one and half hour, Have no Success... Sorry guys but, for me, it's a BLOCKER status. I can't access or compile my projects... Downgrading to v1.6.3... Best Wishes, WCarvalho

I have the same problem. Uninstall Guest Additions, restart Guest OS, and Install Guest Additions again will resolve thie problem.

Hello,

I also have the same problem. Here is my post in the forum: http://forums.virtualbox.org/viewtopic.php?t=8483

Host & Guest : Windows XP Pro SP2. VB 1.6.4
Single PC connected to external DSL modem/router

-Guest configuration (as requested by Frank Mehnert in my forum post):
Windows XP Pro CD with slipstreamed SP2.
No windows updates or patches.
No windows components added.
No other software installed.
English language (did not install or activate any language)

All fairly standard setup:
- Enable : IO APIC, VT-x/AMD-V
- Disabled SATA Controller
- Network Adapter 0 : Enabled, PCnet-FAST III (Am79C973), NAT, Cable Connected

Could not share folder (transient or permanent)
I used the GUI and also tried VboxManage? and 'Net' commands in the host and guest. In the guest, windows explorer, under “My Networking Places” > “Entire Network” > “VirtualBox Shared Folders”, there is Nothing. I understand that the shared folders would show up there. I read the instructions carefully and followed it using the GUI and the command line but Nothing appeared under VirtualBox Shared Folders. Installing Guest Additions 1.6.2 solved the problem. Even after installing 1.6.4 on top of 1.6.2 still works fine.

Hi Guys...

I'm trying somethings here to help pentagonik...

Some tests give me a tip for a workaround...

Install the old G.A. (Guest Additions) v1.6.2 could fit on it...

After that, DO NOT UNINSTALL it... install v1.6.4 over it...

Some guys have success installing G.A. twice... but don't work for me and others...

Well... best regards,

WCarvalho

PS: Be sure you have G.A. v1.6.2 working fine with Shared Folders before install G.A. v1.6.4...

Hi,

As requested I'm adding my comments to this ticket.. Host = openSuse Linux 11.0 kernel 2.6.25.11-0.1-default x86_64 VirtualBox 1.6.4 Guest = Microsoft Windows XP Professional version 2002 Dutch language SP2 applied No software that intervenes with the registry No virusscanner, Windows firewall disabled, no other firewall. VM configuration = - Base mem 1024Mb - Video mem 128 Mb - ACPI enabled - IO APIC enabled - VT-x/AMD-V disabled - PAE/NX enabled - Dynamic VDI - Audio: Host driver ALSA Audio driver, Controller ICH AC97 - Network: Adapter 0, PCnet-FAST III (NAT) - Serial Ports: Port 0, COM1, disconnected, Port 1, COM2, disconnected - USB: disabled - Shared Folders: 1 - Remote display: disabled what happened is: Upgraded VirtualBox from 1.6.2.-> 1.6.4 But started the Windows client with GuestAdditions? 1.6.2 still installed. Connectivity with shared folders was o.k Upgraded GuestAdditions? 1.6.2 -> 1.6.4 (but just by installing it over 1.6.2, so not removing/uninstalling the older version the appropriate way.) This resulted in the loss of connectivity with the shared folders. Uninstalled the GuestAdditions? altogether (via Configuration -> Software -> Uninstall, reinstalled GuestAdditions? 1.6.2 and the connectivity with the shared folders was restored.

If more info is needed I'll be happy to send it, but since the problem can be easily worked around this is no big issue to me....

Best regards, Erik

The issue seems to be only with couple HOST WinXP and GUEST WinXP...

errr...apparently not....:-) I'm experiencing the same problem on a Linux host with a windows guest...

Best regards, Erik

Stumbled on this while trying to find a solution for the same problem on my boss's computer. He upgraded from an earlier version (1.5.6, I believe) to 1.6.4 and can't get shared folder access.

Tried installing guest additions multiple times as suggested by some others with this problem. No success.

Host: Linux- Kubuntu 8.04 (64 bit)
Guest: Windows XP

1.Unistall Guest Additions. 2.Restart Guest OS. 3.Install Guest Additions again. 4.Restart Guest OS.

Now, Shared Folders work well.

aaronwang,

It thread has been opened because uninstall/install G.A. (again and again) isn´t working for everyone...

Regards,

WCarvalho

I can't see Shared Folders from a Windows XP Guest using a Windows Vista Host. However, Shared folders work fine when using an Ubuntu Guest from the same Windows Visa Host. It would seem that the problem is consistently occurring on Windows XP Guests, regardless of the Host type.

Z:\driver\VBoxGuest\VBoxService.exe is missing from guest additions iso' 1.6.2 and 1.6.4 but is in 1.6.0 - No wonder the shared folder function does not work.

Just forget my statement - I don't know what the hell I'm talking about - Sorry.

can you share the folder on the host and then mount in the guest with \\10.0.2.2\sharename ?

I don't know if you are adressing me, Cornbread but if you are, then yes, I can actually access a share created on the host - This might be enough for me, I not quite sure yet, but for now thank you very much :-)

anders2209 Great!

This goes along with my bug: #1822, except mine will blue screen half the time if using \\vboxsvr\share.

There have been guest additions issues since 1.6.0 and they are still not sorted out... even if you get \\vboxsvr\share working it will be much slower than \\10.0.2.2\share (at least in my experience)

If you map the shared folder to a specific drive it should be notably faster that sharing over network. We are aware of some pending issues with shared folders and this is one reason for delaying the 1.6.6 release.
