Hi All, Our network is in workgroup but not in domain because of most of the computers in the office are home edition operating systems. Though we have windows server 2012 as a file server. Our issue is the network slow, by analyzing I found the issue may be with the computers cannot identify the other computers with their computer name, I mean DNS issue in LAN. INTERNET is working fine. The DHCP server giving all computers the gateway ip to firewall ip and DNS primary server as ISP IP which is external one. when I execute the command "nbtstat -r" which gives results related to Netbios /lookup functionality, here in results "Resolved by Broadcast " should be zero but I am getting some 77 value. It means its confirming that some broadcast issue is there because of computers cannot lookup with the computer names. So whether I need to create a local DNS server to resolve computers like "storage-pc" -> 192.168.1.11 ,"antivirus-pc" -> 192.168.1.12 etc.,. ??? but except some pcs all are DHCP clients. Please suggest me ,I have no idea what to do !!!
