dear all hope doing great
Have great day !
I have an issue with dns that not resolving some sites (our organizations sites such as outlook web access, service desk, SharePoint website …etc. ) but any other sites is working normally
these sites usually accessing every day with no issues since long time but before 2 days suddenly we faced an issue with responding these sites
I don’t know if the issue from isp or from my side am just checking with u ?
Note: Im using google dns server 8.8.8.8 8.8.4.4 as per the configuration that I shared on below , I have tried same dns with different ISP company and its works fine (all sites can be accessing normally)
i have problem with responding on these sites even i cant login to skype for business or visit servcie desk site of my company
i dont know it i can do something with my dns and dhcp server on router ? like reset or reconfigure again ???
