ISA Clients >> =?Utf-8?Q?clients_can=C2=B4t_acess?=

by VGhpYWdvIEZyZWl0YXM » Tue, 04 Jul 2006 19:35:01 GMT

Minhas estaes no consegue acessar a internet. J conteceu de um dia ser
possivel acessar a Internet e no outro no. Simplesmente elas no conseguem
ping no servidor proxy. Diz que tem um erro de DNS, mas no achei erro nenhum
j que as vezes todo mundo conecta as vezes no conecta.

No achei nada por ai...tem problemas parecidos...mas no resolveram o meu.

Obrigado,

Htello Tony,

Your old information may still be cached in public DNS servers for awhile 
yet... sometime up to a couple weeks, typically.

You can test whether you're configured properly as follows...
From outside on the Internet, point to a DNS which you know should resolve 
properly (I manage my own public DNS, so this is very easy for me to do... I 
can simply point to my machine).
Or, depending on how you're exposing your website(s), connect by IP address 
instead of by FQDN.

Either way, you're attempting to get the "straight scoop" from your machine 
bypassing any possible DNS issues.

That won't solve Internet name resolution for everyone, but at least you can 
know if you're configured properly and should just wait.

HTH,
Tony Su

Hello

Normally this is not possible to prevent this message, but you can do some 
things to reduce the appearance of it. Try to increase the delay for the 
sever timeout and mybe the response time for the POP server to 200 or 300  
and the SMTP server to  30 or 40

This should help
