Installed and configured NAV, POS2NAV and sales parser to the laptop from FSRI to test using wireless connection. Upon testing, I tried to ping the IP of the NAV server and it was unreachable. I also received a report from Ms. LC Manalang that they were completely unable to connect to NAV. I asked Maiky to ping the IP of the server from the machine of the sales audit staff and it was unreachable as well. Asked help from Elbert, he checked the switch from Payless and was able to ping the server. I also tried to ping the IP of Maiky's PC and the sales audit staff from the server. It seems that the issue was only from the machines of the sales audit users. The isolation will continue tomorrow.
