[SOLVED] Network Configuration -- unable to start a service file

Question

I am following this wiki page (Using Static IP address step) and created /etc/systemd/system/network.service as instructed
[Unit]
Description=Connect to the other pc
Wants=network.target
Before=network.target
BindsTo=sys-subsystem-net-devices-lan.device
After=sys-subsystem-net-devices-lan.device
[Service]
Type=oneshot
RemainAfterExit=yes
EnvironmentFile=/etc/conf.d/network
ExecStart=/sbin/ip link set dev lan up
ExecStart=/sbin/ip addr add 192.168.1.2/24 dev lan
ExecStart=/sbin/ip route add default via 192.168.1.1
ExecStop=/sbin/ip addr flush dev lan
ExecStop=/sbin/ip link set dev lan down
[Install]
WantedBy=multi-user.target
But I am unable to start network.service
$ sudo systemctl start network
Job for network.service failed. See 'systemctl status network.service' and 'journalctl -xn' for details.
$ systemctl status network.service
network.service - Connect to voice
Loaded: loaded (/etc/systemd/system/network.service; enabled)
Active: failed (Result: resources)
$ sudo journalctl -xn

Additional info:
I have connected 2 PCs with LAN (Ethernet) cable and want configure them for exchanging files. Both running Arch Linux. I am following the Network Configuration wiki page from the beginning. Didn't have luck with DHCP/dynamic IP, so trying Static IP this time. Restarting the pc with network.service enabled results in same error (in systemctl --failed). Same error message on both PCs.
Trying to run ExecStart lines one by one:
$ sudo /sbin/ip link set dev lan up
$ sudo /sbin/ip addr add 192.168.1.2/24 dev lan
RTNETLINK answers: File exists
$ sudo /sbin/ip route add default via 192.168.1.1
RTNETLINK answers: File exists
Does this mean there already is IP address and route assigned? If so, how to find out which service has done that? Do I need to remove it? Am I following the right wiki page (didn't find another)?
What am I doing wrong and how can I correct this error? / Point me in right direction.

have you checked if the network file exists?
Oh thanks, that line was causing problems! Now I do have network.service(s) running on both PC's with this content:
[Unit]
Description=Connect to my desktop/laptop
Wants=network.target
Before=network.target
BindsTo=sys-subsystem-net-devices-lan.device
After=sys-subsystem-net-devices-lan.device
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/sbin/ip link set dev lan up
ExecStart=/sbin/ip addr add 192.168.1.2/24 dev lan
ExecStart=/sbin/ip route add default via 192.168.1.1
ExecStop=/sbin/ip addr flush dev lan
ExecStop=/sbin/ip link set dev lan down
[Install]
WantedBy=multi-user.target
I don't get any errors, and this is network's status (on both PCs) when cable is connected
$ sudo systemctl restart network
$ systemctl status network
network.service - Connect to my desktop
Loaded: loaded (/etc/systemd/system/network.service; disabled)
Active: active (exited) since Thu 2013-04-04 22:43:22 AMT; 8s ago
Process: 9761 ExecStop=/sbin/ip link set dev lan down (code=exited, status=0/SUCCESS)
Process: 9757 ExecStop=/sbin/ip addr flush dev lan (code=exited, status=0/SUCCESS)
Process: 9768 ExecStart=/sbin/ip route add default via 192.168.1.1 (code=exited, status=0/SUCCESS)
Process: 9766 ExecStart=/sbin/ip addr add 192.168.1.2/24 dev lan (code=exited, status=0/SUCCESS)
Process: 9764 ExecStart=/sbin/ip link set dev lan up (code=exited, status=0/SUCCESS)
And here wiki page is no more help. How can I test connection?
I try to ping, and it works on both machines (if it's the right thing to test?)
$ ping -c3 192.168.1.2
PING 192.168.1.2 (192.168.1.2) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.039/0.049/0.060/0.011 ms
Now I need to figure out how to share files. Thanks all.
