For security reasons my company needs to disable LLMNR and I just want to find out if anyone’s had issues with this? I understand that its just one step above DNS (similar function) that is used primarily to resolve names to older machines (windows XP/Server 2003) but before we disable this on all of our systems windows visa on up. I was wondering if anyone has had trouble when they disabled this in the past?
it will be disabled from about 500 systems and I have been researching online but haven’t been able to find much on this. I’ll be pushing the GPO out the start of next week.
Thank you for your help guys! And thanks for taking the time to read this.
Have a great day.
As far as I can tell, if you have a functional DNS, you should not need LLMNR at all. It was designed for scenarios in which there is no DNS, such as ad-hoc networks and very small workgroups on a single subnet.
