Hoping to clarify URL requirements for Live Response in Defender for Endpoint. The URLs listed in the Defender URLs spreadsheet online that reference being required for Live Response are:
*.wns.windows.com
login.microsoftonline.com
login.live.com
When you run the client analyzer tool, the MDEClientAnalyzer.txt file contains a results section called
############# Connectivity Check for Live Response URL################
That section lists the following 2 URLs as being tested:
Host: global.notify.windows.com on Port: 443
Host: client.wns.windows.com on Port: 443
I can see no reference to global.notify.windows.com (or *.windows.com) in the URL spreadsheet?
In my testing I have been able to successfully connect via Live Response to servers that show failed connections to global.notify.windows in their MDEClientAnalyzer.txt files.
Can anyone confirm if global.notify.windows.com is a required URL for Live Response?
Thanks

SolutionI've found an older version of the Defender URLs spreadsheet that has an entry for
*.notify.windows.com
The latest version of the spreadsheet doesnt contain this URL anymore and only lists the following requirements for Live Response:
*.wns.windows.com
login.live.com
login.microsoftonline.com
Interestingly in the ChangeLog tab on the latest version of the spreadsheet, it notes that *.notify.windows.com was removed on the 25/01/22. I have a version I downloaded in May this year with that URL present.
Regardless of the above it looks like perhaps they havent updated the connectivity analyzer to remove the test to global.notify.windows.com.
