name mismatch errors

[nogi]

Firstly, my setup:
Build FreeNAS-9.2.1.2-RELEASE-x64 (002022c)
Platform AMD Turion(tm) II Neo N40L Dual-Core Processor
Memory 8170MB

It's a HP Microserver N54L. Since upgrading to 9.2.x, I've been getting the following errors:

Happens with any IP that connects to the server. Googling seems to indicate that it's nothing to worry about but how do I go about fixing what it's complaining about?

I'm getting the same problem, just with slightly different IPs (192.168.1.9X where X is 2, 3, or 4) reported on the console, and the webGUI reporting an alert saying " WARNING: The WebGUI Address could not bind to 192.168.1.93; using wildcard"

I'm afraid I'm an interested novice at this trying this out to repurpose an old Athlon XP 3200+ with 2Gb RAM and two 1Tb SATA-1 disks, so I have to confess I don't know where to start - perhaps by setting a fixed IP in my router? but I thought I'd better search and ask first!
