So I am trying to manage my system and a wireless router using a remote
desktop connection only to find that when I try to connect to any wireless
network Remote Desktop immediately forgets what interface it was started on
and refuses to accept new remote desktop requests until the wireless host it
was connecting to forcefully disconnects it (via unplugging, or other means).
Why does Remote Desktop forget what interface it is on and immediately bind
to the WLAN interface? I have configured windows to give preference to LAN
connections over WLAN connections (Network Connections -> Advanced Settings),
and there is no indication that the original LAN connection has been dropped
since all my other services are running as to be expected.
Because this machine does not have a videocard (waiting for RMA return) I
have managed this machine through Remote Desktop and this bug, yes bug- there
is no reason why it is terminating all connections to the non-affected LAN
interface, is making it impossible for me to manage my wireless router which
lost its configuration after a firmware reflash.
STEPS TO REPRODUCE:
1. Disconnect from wireless if used and connect to LAN via ethernet.
2. Set priority to LAN device over WLAN device in Advanced Settings in
Manage Network Connections (Advanced menubar -> Advanced Settings (hit alt if
necessary to make menubar visible)).
3. Remote into machine using Remote Desktop (TSClient v6).
4. Start -> Connect to. Choose any access point Windows may not recognize.
[If you can only remote in, make sure it is an AP you can turn off]
5. Wait until windows attempts to connect. You will notice Remote Desktop
has lost its connection after about 30 seconds.
6. Ping the machine or access any other service running on it. It should
still be responsive on the LAN interface (as it has not been disconnected).
7. Attempt to reconnect using Remote Desktop over LAN. It should not connect
to that machine at this point.
8. Turn off Access Point you control. Attempt to use Remote desktop to the
machine that was unresponsive over LAN. It will connect now.
Wireless device connects without interrupting and denying Remote Desktop
As long as wireless device is connected, Remote Desktop becomes unavailable
until wireless device has been disconnected or disabled.
Windows Vista Business, fully patched.
LAN [nForce4 Ethernet [ven/dev: 0x10DE/0x0038]: nForce 15.00 driver
WLAN [Linksys Wireless-G PCI [ven/dev: 0x1814/0x0301]: Windows WHQL driver
Note: This system does not currently have a videocard and can only be
accessed via remote desktop.
