A set of interface system of external network is set up in the local area network environment which can not connect to the Internet, and the access is very slow.

cannot connect to the Internet . A set of interface system has been set up in the LAN environment where several public network domain names are involved. No matter what browser you use windows PC to access, it is very slow to return unresolvable. If you visit it with linux, you can return it directly. Is there any way to set the dns parsing timeout for windows?
Note: no DNS server has been built in the private network
