RDP-Server very slow then 1 connection unreachable

[dk_lcom]

Hello,

the RDP-Server have some trouble if the client gets unreachable. All another connections (available and future) are extreme slow and unusable.

The problem comes up then someone change from LAN to WLAN, without cancel conventional the connection before.

To reproduction that issue do the follow:

1. Enable RDP for a VM
2. Start the VM
3. Connect via RDP-Client to the VM

Way 1:

4. Change the IP ( ifconfig eth0 192.168.1.15 netmask 255.255.0.0 )
5. Close the connection and reconnect

Way 2:

4. Unplug the networkcable physical.
5. Connect with a another PC

Now the RDP connection is unusable / heavy slow.
