LAN pode se conectar com o nome do computador, mas não com o IP

Question

Eu tenho uma pequena rede de escritórios, cerca de 20 máquinas, todas usando o Windows 7 e o problema descrito no título.

O Computer TM (o criador de problemas) quer falar com o Computer FS (um servidor de arquivos), mas só o fará através do nome COMPUTER-FS . Um endereço IP não funcionará.

Os fatos:

• FS pode pingar TM com IP
• TM pode não pingar FS com IP
• TM e FS podem fazer ping entre si usando nomes
• Todas as outras máquinas funcionam como esperado

Em um problema possivelmente relacionado, quando os usuários abrem o Network explorer, apenas algumas máquinas ficam visíveis. Às vezes eles são todos visíveis, às vezes não. Esse problema vem ocorrendo há várias semanas; o problema do ping começou hoje.

Como posso resolver isso e ter o TM capaz de fazer o ping do FS usando um IP?

EDITAR aqui está o ipconfig /all do criador de problemas:

Answer 1

Quando você faz ping pelo nome, você recebe o endereço ipv6 retornado? Vista e acima têm isso habilitado por padrão, então você não precisa de uma rede ipv4 configurada corretamente para se conectar.

Quais são as configurações do ipv4? Eles estão na mesma faixa de rede, com uma máscara de sub-rede adequada?
