"Server not found" problem on FF 39, Win 7

I have gone through the whole thread couple of times, and haven't seen anything regarding: do you have devices that work ok? or is this the only one that is connected?

Since it is not a hardware issue, it is bound to be fixable one way or another.

Please run cmd as admin:

Code:

sfc /scannow

If corruption is found also run in cmd:

Code:

findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >"%userprofile%\desktop\sfcdetails.txt"

and attach the sfcdetails.txt here

OK, here is the chronology.
I ran cmd yesterday evening:
sfc /scannow
The corruption was found. It said that the repair will be completed on the next boot.
Today I turned on my PC expecting that finally everything will be OK. But, as you probably expect, it wasn't.
I could not connect to internet at all. There was an red X mark between "Network" and "Internet" in Network and Sharing Center.
(Note that when I had "usual" messages "Server not found" and "The connection has timed out" that red X mark wasn't there. The connection was OK then.)
I tried to troubleshoot it, but I only succeeded in getting this message. So, I switched from Obtain IP address automatically and Obtain DNS server address automatically to - Use the following IP address. I entered the usual numbers.
First I tried with these numbers in Preffered DNS Server and Alternate DNS Server fields > 8.8.8.8 and 8.8.4.4
Nothing happened.
Then I entered 208.67.222.222 and 208.67.220.220.
Nothing happened.

In order to connect to internet, I pulled out the cord from Marvell Yukon adapter and plugged it in Realtek PCI GBE. Now the connection is OK, but I don't know for how long.
Here is sfcdetails.txt

While I am at it, this is copied directly from the cmd screen after running sfc /scannow

(btw - Server not found message started to appear again)

Ok, there are a few corruptions that need to be taken care of.

Please follow Step 4 of Windows Update Posting Instructions. If CBS.zip exceeds the file limit, exclude the older CBSPersist files from the zip.

Once you attach the CBS.zip file, I will PM our expert on fixing these corruption.

I will upload compressed CBS folder (61 MB) in my Dropbox folder and send you a PM link to it.

Alright, there is nothing personal in those files by the way, you can link here without worry.

PM sent to NoelDP, expect him to respond to you (may take a day or two depending on his current load).

OK.
