pop-up message

When I turned on my computer I  received a pop-up message saying that ..'computer 224(+other numbers)......is attempting to access systemuiserver (not sure of spelling) on your....(not sure of the rest because the message went away after about 15 sec).

There was a button asking me to accept or not accept.

What am I supposed to do with this message?  How am I supposed to know what that long computer number means?

Thank you,

Quote from above site;

"...allowing traffic to/from 224.0.0.251 (the multicast broadcast address) on your firewall.

Don't worry, it's local traffic and shouldn't go to the outside world (the 224.x.x.x range is the multicast equivalent of 192.168.x.x or 10.x.x.x). But if you want to be sure, block it from the WAN side of your connection but allow it internally."
