virtualbox.org

Hi

My first post here because I've a little issue and I didn't found similar with answers.

I use VirtualBox 2.2 on a Linux Debian R4 server. I run a VM with Windows Home Server 2003 as the Guest OS, and access to it with VRDP throught the network (so, from my main computer which run Seven Beta 7000 x64)
For testing purpose I have an other VM with Debian R5.

The issue:

With the "Home Server" VM, VRDP is totally unstable. I loose connection every 5-10sec and need to reconnecte again & again.
The intial RDP connexion is fine, I see the OS loading, and the issue begin when I have to connect the user on WHS (CTRL+ALT+END for login). There's no connection lost until I log the user on WHS.
I've found that connection is lost each time try to access network configuration on the guest.. but it's not the only way to. Even the Home server console may crash the RDP connection.

Seem's that any network access on WHS has an impact on the network Interface. So I tried all the different mode: NAT, birdged, hostonly and internal... without success...

Have to say that the connecion is totally stable with the Debian R5 VM (with, or without GUI like Gnome).

As I searched where the issue can be. I tried the same thing with VirtualBox on my main computer wich run Seven Build 7000 x64. (VB2.x run pretty well on it).
There I've tried VRDP with 2 VM:
One with a later Seven Build (x86), one with the same Windows Home Server VM than on the Debian Server (I've made a copy off the *.vdi disk files).
And you know what ? VRDP run totally fine with the Seven VM... but same issues with the Home Server VM VRDP lost connection again and again and again.

So:
2 differents Physical Machines (the server and my main computer)
2 differents Hosts OS (Debian R4 and Seven Beta)
As Localhost or over network host
3 differents Guest OS (Debian R5, Seven x86 pre-RC, Windows Home Server 2003)

But same issue for only one guest OS.


Is there Somebody who have experient this issue with WHS and how can I go throught please ?

Thanks for answering.


Edit: Oups, I"ve made a mistake. Posted on the wrong section... Sorry

Found something..

Reinstallation of the guest additionnals and disabling clipboard on the VM configuration stop the issue on the Windows guest.

I try a reinstallation of Home Server on the linux server (I did the test after the begin of the new installation )... wait & see

Damn !!

There's something I really don't understand!
After reinstallation of WHS under the WM on the Debian Server, RDP work fine (as during all the installation). But soon as I install the GuestAdditions and reboot WHS.. badaboom! RDP lost connection again, again & again !!!

WTF!!

I use exacty the same VM configuration as on my main computer (on which it work fine now).

Please help ! what can I try now ?

INow I think that the issue come from mouse integration. For example if I make a selection square on the desktop of WHS the connexion is lost... and when I try to reconnecte I can see the selection square and badaboom deconnexion! .. again and again ...

The only error message is:

"Because of a protocole error, this session will be disconnected. Please try connecting to the remote computer again"

Try turning off the 3D effects in the VBox setting of the WHS machine and see if this helps. About a year ago there was an issue like this and it had to do with the visual styles in Vista. Maybe MS has given WHS a new element for everyone to deal with.

Hi

Thanks for reply

If you talk about "3D acceleration" in VB settings, it's turned off (never turned ON for this VM because for the Server it's useless).

If you talk about the desktop engine of Windows home Server: It is based on Server 2003, so there's no 3D desktop like Aero in Vista, rendering engine is the same as in XP (GDI+).

BTW, I've found a way to go through the issue. I use the RDP of WHS instead of VRDP. The harder to do was to configure the network of WHS, but now I can acces to my server thanks to the RDP of WHS.


But I would be thanksfull if someone help me to find why I have thise issue with VRDP only with this WM and only on my server system.

Hi

Back for news.

Today I try to connect to the VRDP over the web with and XP SP3 computer. And it works great!
So the point is between VRDP, WHS and Windows Seven over network (locally it works fine with WHS on the Seven host) !
At this time I use Seven x64 beta, toninght I will install Seven RC x64 ... will see if the issue is still there or not.

Incredible
