Virtualbox internal network [Help]

[jakes9x]

I specified DHCP server with this command and it was successful
VBoxManage dhcpserver add --netname intnet --ip 192.168.56.1 --netmask 255.255.255.0 --lowerip 192.168.1.2 --upperip 192.168.56.254 --enable

Then i opened cmd in my original pc {host pc} and gave this command for internal network
C://Program Files\Oracle\VirtualBox>VBoxManage modifyvm "my virtualbox name" --nic<x> intnet
and this
C://Program Files\Oracle\VirtualBox>VBoxManage modifyvm "my virtualbox name" --intnet<x> "network name"

And it showed me an error "The system cannot find the specified file"
What is wrong with this command i used it exactly as shown in virtualbox manual

You did replace the "<x>" with the NIC number?

From the Network tab in the VM settings; it says "Adapter <x>" on the tabs...
