ESXi Version 6.5.0 Build 4887370
Dell PowerEdge R710
2x Intel Xeon CPU x5660 @ 2.80 GHz
128 GB Memory
The Problem:
1. This server had been running normally until a recent power outtage
2. Instead of listing a home address of 192.168.xxx.xx, it is defaulting to 169.254.141.138 (Waiting for DHCP...)
3. Gives the following message: "Warning: DHCP Lookup failed. You may be unable to access this system until you customize its network configuration"
Attempted Solutions
4. Restart ESXi - restart completes, still shows as in #2 above, still gives error as in #3 above
5. Restart Management Network - reports success; returning to the main screen gets home address of 0.0.0.0 while it (presumably) is attempting to reach DHCP for assignment. Returns error in #3 above after waiting 90 seconds or so.
Additional Information
6. There is not an IT department or network department to consult - we're a small (read as ~8 people) firm
7. I am an admitted neophyte in regards to this, so kindly bear with my ignorance - I don't know what I don't know, so I'm hoping someone has the patience and knowledge to assist here 
8. Tried "Test Management Network" option...ESXi attempts ping 208.67.222.xxx and 208.67.220.xxx and fails at both
9/ I've attempted to do my due diligence and scoured the web for similar cases - and I see similar issues, but never a solution. I've checked through the forums, as well as for any documentation or tutorials but have not found anything, yet.
Thanks in advance for anyone willing to lend time and assistance. They are very much appreciated!
