What is the domain "nrb.footprintdns.com"??
Hello Everyone
From 3/2/2018, when I access my SharePoint site the following certificate site? is displayed.
https://37CFD84CE79EF6104C98E018AE6ABD10.nrb.footprintdns.com
And request me to type account and pw.. Although I entered my PW I cant access my sharepoint site. I want to know why? And how can I access my site.
So I want to ask the following questions:
1.When I access the above URL Office 365 sign in page is appeared what is the relationship between Microsoft?
2.Since today Microsoft is beginning to use the [nrb.footprintdns.com] domain?
3. What is the purpose that Microsoft use the [nrb.footprintdns.com]?
4. I googled and I found the following site. And I can also search the domain [37CFD84CE79EF6104C98E018AE6ABD10.nrb.footprintdns.com] in there.
I really don’t understand why microsoft use the thteats? Site for what purpose DNS?
I did not have this situation previous to 3/2/2018.
Can anyone tell me how to resolve this situation..
I do not have any certificate knowledge so I will very appreciate if anyone can tell me the reason simply.
Thanks.

Why is there no response from Microsoft on this?
This domain is blocked by my adblocker under the category "Spyware filter" though it is clearly owned by Microsoft.
We need an official explanation of what this is doing. Most importantly, we need to understand why this is not listed in the official URL list for Office 365.
We also need to know the impact of this domain being blocked which is clearly is being by some security tools.
Fiddler to my sharepoint site displays this: The server (0d255cb7441615dbb825de4d81cddac7.nrb.footprintdns.com) presented a certificate that did not validate, because it was issued to a different host.
Well since Microsoft have declined to respond. I recommend that everyone just blocks access to the domain.
I'm also seeing network traffic for this domain and it seems to be loading a 1px .gif image to the page.
The problem here is that the image takes multiple seconds to be loaded!
Same here Kas blocking the request since two day
Is nrb.footprintds.com safe - Kaspersky says no - if so, why is it not safe

Simple- Kasp says that the domain safety certificate is issued by some one, on whom either Kasp has no confidence on, or doesn't even know about it. In that case, the domain could be safe, could be unsafe (hackable), or could be even malicious by itself.
If I have Kasp on, I will go by its advice. Even if it is against MS' own domain (which it isn't, but is a sub-let domain). Let MS do its security analysis and ensure that the firewalls don't flag it down.
I cannot comment on Sharepoint, Word, Excel etc etc etc but I did notice it when using Outlook 365. Noticing this certificate issue for myself on my computer, I did some research and discovered that if you turn off the "Coming Soon" button in the top right corner of Outlook, the "Invalid Certificate" issue went away.
It seems to me that by activating this part of office, it is allowing Microsoft to send adverts about their products. I am lucky that I am using Windows 7 where that OS was never designed to be one large advertising platform where Windows 10 is.
I haven't investigated too deeply but after seeing this thread, I though I would give my 2 cents worth. I hope it helps some people out.
Cheers.

How can I disable and/or opt-out of this service?
Our SharePoint implementation is extremely slow. Hundreds of files are downloaded on every request, many of them unnecessary, and this represents a large portion of them. I'm trying to speed up the user experience. Please do not respond by saying it is a necessary feature, or that it doesn't affect our site, because both of those responses would be wrong and unhelpful.
Thank you.
Well it´s about 3 months ago now. Microsoft missed to add FQDN to Office 365 endpoints list (https://docs.microsoft.com/en-us/office365/enterprise/office-365-endpoints), but confirmed that this one is added to the code for service improvements.
For me as a customer, I expect that Microsoft becomes active much faster.
- Sorry, but I'm not following you here: when is that Url displayed?
Can someone explain the purpose of *.footprintdns.com domains? To be specific what *.nrb.footprintdns.com does? Something weird about this domain.
Attempts to visit blocked websites (2)
Any progress with knowing what this URL - nrb.footprintdns.com is for? Detecting it from user using o365 services.
- No, nobody from Microsoft has bothered to reply. I strongly recommend blocking the domain. I can't find anything it impacts.
It seems like the calls are made from a javascript called fp.js, which is downloaded from here:
https://r4.res.office365.com/footprint/v2.6/scripts/fp.js
(just click the link if you want to read the source code)
Still no response from MS ? Till today it was silent, but now, all the computers are getting this message, and the firewall installed is blocking it (the security certificate is not from a known or approved agency) Anyway, it isn't affecting the operation, so I think it is immaterial, except the nuisance value. But which group of microsoft is tryying to fish here ? The Office 365 group or the windows ?
- hmm, last days my KAV starts to show me this warning with site nrb.footprintdns.com with invalid certificate...
But I'm not sure what exactly is trying to connect there...(and why)
MS, any reply ??
ThanksMy KAV is blocking access due to invalid certificate past 2 days now, too, saying, that these domains are accessed by Outlook. I saw the same in the past, but way less frequently.
