Yes, I used the same cable and port, but finally I found that the problem was in the switch, as Tiago said. Tank you all very much. -----Original Message----- From: Jim Harrison [mailto:jim@xxxxxxxxxxxx] Sent: Friday, June 04, 2004 1:21 AM To: [ISAserver.org Discussion List] Subject: [isalist] Re: External network connection show as disconnected every some time. http://www.ISAserver.org What do you find in the system event logs?

I have the network connections visible in my systray. Every some time the network connection of the external interface is shown as disconnected and after 1 or 2 seconds it is show as reconnect again. I have changed the network adapter and the problem persists; and I have used my laptop connected to this physical line without having that problem. So I have concluded that the problem is ISA Server (I think so). Have some one any way to troubleshoot that problem? Thanks in advance. Lic.
