What is the domain "nrb.footprintdns.com"??
The domain nrb.footprintdns.com is owned by Microsoft and represents servers in Microsoft datacenters. It is used for telemetry purposes that comply with Microsoft privacy commitments that you can read about at: https://products.office.com/en-us/business/office-365-trust-center-privacy. Data sent to this domain is used to identify network connectivity and performance issues and to support improvements to the service. We have plans to rename it to be more descriptive, and to publish it at the Office 365 IP Address and URL publishing site at http://aka.ms/o365ip. If you have any problems using Office 365 related to this, please raise a support incident so that we can assist at https://support.office.com/
But I'm not sure what exactly is trying to connect there...(and why)
MS, any reply ??
Thanks
My 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.
Not sure if this is the place to post, but as others have identified Microsoft Office and Outlook as involved, I'll make my contribution.
My Kaspersky Total Security application is identifying an invalid certificate. The source program is listed as Microsoft Office in the popup. The certificate in question lists the related certificate site as outlook.live.com, and the detailed report lists the involved program as Microsoft Word! I have attached the pertinent screenshots. As you can see, the issue is very repetitive, with a different prefix for the url each time. Comment would be appreciated.
