Hi If you stop (freeze) the SMTP queue on the Exchange server does this also return your Internet connection to normal? Is there a possibility that your users could be sending or receiving very large emails which are causing the connection to be saturated with SMTP traffic? Cheers, Steve

Hello, in our company we're are having a strange problem. The internet connection keeps always on disconnecting and the ping to outside is very high. However if i disconnect the Exchange server from the Network, then everything go back to normal but when i bring back the server the ping goes up again. I searched if it was a firewall problem or the modem but then i noticed that exchange is causing this problem. Does anyone have a idea maybe ?

Hi, i made just what you did, the connection went back to normal, then i saw that in the queue there was like 30 times the same email in the with always 8mb attachment. I cleaned the queue and now it seems to work well again. Thanks

Great news. Glad you found the cause. Cheers, Steve
