I am setting up a business server for a small office use with 5 users / 5 devices or so. Nothing elaborate here.
J’ai set up a SINGLE Lenovo TS440 server (single NIC) with Windows Server 2012 R2 Essentials. Step by step via install and wizards. No secondary domain controller. I will look into other secondary solutions when I can. I do not want to purchase another server, but I do understand the importance of it.
I set up a domain administrator account which I use for all the workstations and le serveur during this setup process. Users will not have admin privs, and no local accounts will be on the workstations so they cannot get into workstation without server authentication.
Nous avons a Comcast Business router (CISCO DC3939B with wifi) with a dynamic external IP that hardly ever changes. We also have a TrendNet switch, TEG S80g.
The coax cable internet comes in to the router then router to switch.
The server and about 3 workstations and 2 devices feed in to the switch, and tVoici a couple wireless devices.
My problem is that after testing the system by removing power to the router and turning off the internet, the workstations can no longer authenticate correctly. Everything works fine with internet available, but J’ai besoin de to assurez-vous that the workstations can still communicate with each other and le serveur when the internet goes down. I guess J’ai besoin de this WSE 2012 R2 server network to work as if there wasn’t internet access to begin with.
Does this maybe have something to do with the router doing DHCP? I am not sure if DHCP can be disabled in the router.
The errors I get when the workstations try to connect to other workstations is that they require l’utilisateurname and pw again, and sometimes they fail to connect. The server isn’t down, just the internet. At first J’étais getting a prompt to turn on Network Discovery, which I did (not public, but private), but we still have this AD problem.
If I left any important details out, please let me know and I can round those up.
