Recently had a colleague call me , after a mainboard switch over , the DNS server was not working
- Could ping the server from Remote Device
- Nslookup from the device would come back with (Request Timed Out)
- I could NSLOOKUP local host on the SBS Server
- Restarted the DNS Server Service , enabled Logging could see Items
- DNS Server was listening on correct IP interfaces
Found out during the main board swap out , the Subnet Mask of 255.255.255.255 had been set instead 255.255.255.0
What does this do? It sets a Single Device on the Subnet , which means it can’t route to the Default Gateway
If you did want to do this , it should be set to 255.255.255.252 ( two items on the Subnet ) for 192.168.0.1 and .2
