If you have hosted Hospital ERP Software on your local server and want to use in local LAN network then your Hospital ERP Software hosting machine should have static ip address (not be dynamic assigned by your modem DHCP). Here suppose your server hosting machine have ip address 192.168.1.2 then when you are installing Hospital ERP Software then you should type 192.168.1.2/myhospital/ not localhost/myhospital/ other wise you can not access Hospital ERP Software from other computers in your LAN and will redirect to localhost/myhospital/ url. Now if you have installed Hospital ERP Software using localhost/myhospital/ then you can correct this by editing base_url value in file /application/config/config.php . In this file change localhost to your hosting server static ip address like 192.168.1.2 .
