Not sure why there is a red X mark on the Open VPN network adapter(TAP-Windows Adapter V9)

We use a hosted finance system outside to our network.  The guys who host had asked me to open port 1194 on the fire wall. The firewall team had opened this port for us. The hosted system connects through the open Open VPN, The open VPN is set to start automatically .
They had given us few IP address  10.x.x.x  range  and told that I must be able to ping these IP addresses  from our network.

When I ping I get destination net unreachable.  

When I install the open VPN on my Laptop at home with all certificates and credentials it successfully pings these IP addresses 10.x.x.x

One thing I noted was, when I went to the network properties  in my office.
I can see the Local area connection2  (TAP-Windows Adapter V9)and there is red X mark and it says Network cable unplugged.

I restarted the open VPN services several times,
I disabled IPV6 and did a repair on the adapter still I am not able to ping the IP addresses that was provided by the hosted guys.

Not sure why there is a red X mark on the adapter and how to ping this Ip addresses.

Any help much appreciated.

The TAP adapter can be set up to have application controlled connection state. If OpenVPN runs, and that state is not set up as connected, OpenVPN has not found it, or could not connect to remote target.
You should check the OpenVPN logfile.

I found something interesting, on the laptop which was connected through a hot spot, i did a ipconfig and made a note of the IP on the Open VPN - TAP adapter.

I then disconnected that laptop  and gave the same IP on the Open VPN - TAP adapters as a static on my PC and the red X mark disappeared and the IP 10.x.x.x started pinging successfully  and all works ok now.

So not sure how the Laptop gets an  IP. Is it  from their DHCP ?
and why my PC is not getting a IP and  i have to do a static entry. Please let me know is something restricted on the firewall \core switch  as my PC is not able to get the IP dynamically.

By all means, please check your OpenVPN log!!!
I cannot see any reason offhand that the OpenVPN server was not able to hand out an IP address. And that setting a static IP should work is even more confusing.

So, please go into your OVPN file used to connect, change or add verb to at least 3 (or higher), and then connect. The logfile generated hopefully will tell the actions performed, and failures. If there is no log file, you'll have to watch the OpenVPN window for info.

Go into the OVPN file with an editor (best to use WordPad, as the file might have Unix formatting). The file should be in your OpenVPN program folder under config\.
Then add verb 3, or change an existing verb setting to at least that value.
Start the OpenVPN connection. You should now see a log window, or at least have a log file in the OpenVPN's log\ folder.
