Ok, so I have an actual error message now
C:\Users\Peter>net view \\169.254.184.206
System error 53 has occurred.
The network path was not found.
Again, I can ping the machine:
C:\Users\Peter>ping 169.254.184.206

Searching for "System error 53 has occurred" leads to
this page which lists the following:
1) if it is domain environment, check your WINS;
2) if it is peer-to-peer workgroup, enable NetBIOS over TCP/IP;
3) make sure the machine is running;
4) make sure file and Printer Share enabled on remote computer;
5) make sure client for ms networks is enabled on local computer;
6) make sure you type the correct name.
7) Make sure no firewall running or any security setting.
1 doesn't apply, 2 didn't work, 5 is enabled, toggling firewall made no difference.
I'm currently thinking it's got to be something in Local Area Connection Properties and/or TCP/IPv4 properties - something I inadvertently changed and whatever configuration I try I can't find the magic values that it had before. :(
