Auth Session is invalid

[chinajade]

So.
Changed router, [size=+1]changed internet provider[/size], switched off all antivirus programs, reinstall network card settings and TCP/IP protocol - all time the same.
It not internet connection problem cause all time navigation server was reachable but bot lost connection with it or so.
What seems to be the cause of the trouble?

Hi, MX2012,

Are you by any chance running redundant connections to two different ISPs simultaneously? (If so, that is uncommon and very sophisticated. )

Alas, this can also be a problem as Windows frequently doesn't handle this situation well. It finds two different paths to the same location, and gets 'confused' as to which should be used. This results in packet loss.

If you are running redundant ISPs, please shut one side down, and see if the problem goes away. If so, that will confirm its a Windows bug being aggravated.

cheers,

Hi again, Mmx2012,

Thats kinda curious. Largely, DNS should be resolved without leaving your machine—as they should be cached. If they do leave your machine, most routers provide an interim caching DNS server.

Are you seeing them leave your machine or premise?

You might want to look through the "To Remedy a non-specific Authentication Failed:" section of this article, and make certain all of your network mechanisms are intact. Particularly, you're looking for damaged hosts file, 'poisoned caches', loopback devices, and such.

So, it was a lot tests etc.
I need you help with analyse TCP dump.
I've capturet disconect moment by WireShark.
Ofc you know protocol and can very fast see what wrong with it.
If you can help me with it tell me where to put this dump file.

Tnx.

Hello
I have the same problem, but when I put in DMZ everything works. I would like to know which port I should open.
