If you are using Root Hints, it may be necessary to update your root hints from time to time, as my good MVP […]

For as long as I can remember, Microsoft’s Small Business Server (SBS) and Essentials Server would default to using .local for the internal domain suffix during installation. So, if your company name was Contoso, it would create Contoso.local as your internal domain. And for me, using .local worked great all these years. The customer would […]
