The ENC28J60 is the Ethernet controller... not the discovery board.

Thanks Cutty, I will have a look on the board and search for an replacement. The IC should not be too expensive.
GOOD NEWS EVERYONE,
I thought about the IC but I also I thought that freezing the station would at least do something.
So I froze the station, dried it quickly to prevent buildup of dew and once there was no dew depositing on the station I hooked it to power.
The display was stills showing -70C (an error as my freezer is not that good) but it connected.
Disabled DHCP on the board side and allocated an fixed IP to both the board and router side.
I hope this redneck type of fix will hold until I have the time to tinker with the board.
So in the end the DHCP error was on the station side. The important thing is that the mystery was solved even if I would not recommend anyone to freeze their station as an temporary fix.
Will let you know how long this fix will hold.

That is great!
Which may indicate a poor solder connection on the Ethernet controller, or associated components.
Us 'old' techs used a 'freeze' spray of Freon, and its cousins, to narrow such things down to component level.
Good Job!

Yeah, thanks!
Once I began thinking about the IC I also thought that there might be an issue regarding soldering and it might be worth it to throw the whole thing into the freezer. On the other hand I clearly recall checking each point with the magnifying glass.
I do expect the issue to return at some point. At least this time I know where to look for the issue.
But for the moment: if it ain't broke don't fix it
Thanks Cutty and Steph for all the support and help!

Because the station was down again for some time (behaving strangely, rebooting, stalling), I finally allocated much needed attention to the issue of the ENC28J60 (after checking all the solder points on the board under the microscope and all seemed OK).
The issue (and the fix) was surprisingly mundane... as I noticed that ENC28J60 was not sitting exactly parallel to the discovery board (one side looked a little bit tilted relative to the socket)
In the end it was just an issue of pushing [ENC28J60 harder in its socket (it seems it got loose a little bit).
I noticed some people just hard soldered directly the ENC28J60 to the board (not soldering the provided socked and pushing the IC in). Regarding the unlikely case of this issue returning, is it preferable to solder the ENC28J60 directly to the board or should I look for a new socked? (I am quite confident the problem should not return as I applied more the sufficient force).
