We host a website locally for employees to use to complete their work. We noticed once and a while an employee will lose connection to the local website and can not access the site anymore even though other employees still can. We found that the machines that are having the problem have static IP's and according to one employee it happens when they come back from a break.
The employee only loses access to that site but still can access the internet and OTHER local websites we host on different servers. Ping & Traceroute work fine from the PC to the server they can not access.
Unplugging the network cable and plugging it back in fixes the problem.
Employees PC - Windows XP & Windows 7 ( Ones losing connection to server )
Server - Linux ( Centos )
Employees are accessing the server through chrome using the domain name not IP ( HTTPS )
