Maybe. So how do I check it and then fix that if it did??
Thanks.
MC on the Mac should update that address automatically.
I'm assuming JRemote is on the Lan with the Mac.
You can go into Options->Media Network->Click on the access key and do Test connection to this server.
If your Mac has a DHCP address on your Lan you might want to consider giving it a fixed lease (on the router) or a static address outside of the DHCP address range but in the same Lan address block.
