I have attached a wireshark .JPG to this question, so you can see exactly what I'm talking about.
It is hard to describe the problem, but I'll try ...
For about 2 weeks last year, I was contracting at a site as a daily IT helper ...
The netBIOS name of each PC on site was something like this:
The AL was the company name ... the number is the location of the PC ... and the last part is the OS on the system.
Since that time ... I always see these DARN broadcast messages from my laptop when I do any Wireshark work (I've cleared my DNS cache dozens of times ... I'm using DHCP 99.99% of the time, and I've check all the TABS for network configuration (even the advance TABS ... etc.)
I simply cannot find 'where' on my laptop this reference to the old company is located at.
I hope this make sense.
I have not been back to the site where this started at in nearly 6 months ...
I have no idea why, how, or where this is 'stuck' in my networking configuration process.
