I have a virtual windows server 2008 r2 with 2 virtual network adapters, one is part of a domain and the other isn't. When I ping to a specific PC that is part of the domain it connects to it through the second network adapter (the one that isn't in the domain) and I tried to change that with a static route:

ROUTE ADD -P <target PC's IP> MASK <Subnet mask from ipconfig> <Default Gateway of the adapter in the domain> if <tried it with all possible interfaces>

Unfortunately, that didn't work, so I'll be happy to be assisted with How to make this static route so my server will connect to the PC that is in the domain through the network adapter that is in the domain?

Output of route print and ipconfig:

As far as I understand the part of Tunnel adapter is for IPv6 (isn't it?) and the server is connected to the network - both of the domain and outside it. –  Moshisho Jan 28 at 15:43
    
@Moshisho Yeah, your network adapters are reported as connected. You're not using the Tunnel adapter in this set up but Windows insist on telling you all about it. –  ETL Jan 28 at 15:48

Part of the problem is that you have 2 DEFAULT GATEWAY which violates the meaning of DEFAULT GATEWAY. Put the default gateway only on one interface. Then with static route, direct the traffic you want to go via the other interface.

For example, LAN1 192.168.123.13 Mask 255.255.255.0 and GW 192.168.128.254. That will get all traffic to 192.168.123.x and anything to any other network will be directed through the gateway.

But then add LAN2 192.168.137.15 Mask 255.255.255.0 WITHOUT any default gateway. That will automatically create a routing entry that 192.168.137.x will go through this interface instead of the Default Gateway. Now, if you want other traffic to go through that interface, you can create a static route like:

ROUTE ADD -P 192.168.33.0 MASK 255.255.255.0 192.168.137.1

That will send the traffic going to 192.168.33.x through LAN2 as 192.168.137.1 is in the same network as LAN2 interface.
