Hello,
I am getting the following errors when starting a VM -

00:00:07.467549 VRDP: TCP server failed to bind to a port: default 3389, range [3389]
00:00:07.467808 VRDP: Failed to start VRDP-IN thread, rc = VERR_NET_ADDRESS_IN_USE
00:00:07.468570 VRDP: TCP server closed.
00:00:07.469262 VRDE: Warning: failed to launch VRDE server (VERR_NET_ADDRESS_IN_USE): VirtualBox Remote Desktop Extension server can't bind to the port(s): 3389

This is my first foray into VirtualBox - The person who set this machine up is no longer with the company and when trouble arose I was tasked with resolving it. I have tried numerous things and can't seem to get it sorted. The machine starts, but I can't ping it which then means I can't RDP to it or access shared resources on it. I have attached the log file and the results of vboxmanage showvminfo DEV-EVANS-SQL02 > showvminfo.txt. I have also included the showvminfo results below.

On Windows hosts, the standard RDP port 3389 is already in use. In the VM configuration, configure the VRDP server to use another port (e.g. 3390).

I get the same error with the new port number.

00:00:07.467549 VRDP: TCP server failed to bind to a port: default 3389, range [3389]

is now

00:00:07.467549 VRDP: TCP server failed to bind to a port: default 3389, range [3390]

Did you check that the combination of IP address and port that you're trying to bind to is free on your host?

Could you provide a quick lesson in how the address/port actually works between the host and guest?

This machine was working without issue (connected to it with the same RDP connection I use to connect to all my other servers) until one day it didn't. The original error was about a missing extension pack. It seems that a few files were missing from the extension pack directory. I remedied that by installing the identical version of VirtualBox Manager on my laptop and moving the missing files over to the actual host. The original error disappeared and this new error is now happening.

Is the vdreaddress supposed to be the IP address of the guest (therefore, obviously can't be an in use IP address on the network)?

Is the vdreport supposed to be unique from any ports used on the host?

And if I was using a standard RDP connection in the past to connect to the guest, wouldn't it have been using port 3389?

Another question, being the VirtualBox user that I am, is there any risk to uninstalling and reinstalling VirtualBox Manager on the host server? The GUI console has never worked on the host - all changes have to be made by command line and I would love to have the GUI functioning as well.

The VirtualBox VRDP implementation (part of the VirtualBox Extension Pack) starts its own RDP server on the host H, not on the guest G. The display content from G isn't transferred to H via any network connection in this case. You simply connect from your RDP client running on C to the host H. If C == H, you can also use 127.0.0.1 (localhost) as destination IPv4 address. Because the Windows OS on the host usually starts its own RDP server on port 3389, the VirtualBox RDP server has to use another port.

More details are documented in the VirtualBox User Manual: 7.1. Remote Display (VRDP Support).

Other parts of your description sound to me like you should completely uninstall and reinstall VirtualBox on your host. This usually doesn't delete your existing VMs, so you can re-add them afterwards.

Thanks. I will give that a go. I will backup the vmdk files before I begin - gotta love a safety net.

Thanks for your help. In the end I did completely uninstall and reinstall VirtualBox. The VM was preserved and in fact, it was already visible when I started the console. Once I got the IP address on the NIC set properly and the vdreport set to an unused port I was able to ping, RDP, and see shared resources once again.

How do I mark a post 'Solved'?

Edit the title of your initial post by prepending "[Solved] " (without the quotes, of course ).
