From: Lassiter on 4 May 2010 20:32 We loose Internet every few weeks and a restart of the server seems to fix it. This time when it happened I checked the router remotely, before rebooting the SBS 2003 SP2 server, and did a ping and trace and all seems good with it… which tells me that I have internet access but the SBS server is not allowing it. On another note I can remotely connect using gotomypc successfully when this occurs and can access both the server and clients. We have a DSL modem w/ a fixed IP and it is setup as a pass-through device to the router. I have the server setup as the DNS server and not the router. Like I said we loose Internet access only after the servers been up for a week or two. Any advice? Thanks

So it looks like DNS is okay, as is the internet connection. > We have a DSL modem w/ a fixed IP and it is setup as a pass-through device > to the router.

Thanks When you say you loose internet access can I assume from what you've said that it is only HTTP (i.e. browsing) that you are talking about? Do you use the SBS server as a proxy server (or run a proxy server on it)? If so is browsing okay if you don't? Also, as a way of checking HTTP download cryping (from http://www.cryer.co.uk/downloads/cryping/) and when internet next fails try (at the command line): cryping -http www.google.com That will do an "http ping", basically checking whether it can connect to the named server via http. If that works and your browser doesn't then it might be a firwall or anti-virus issue - although that would be unlikey given that its only after a period of time that it fails. Does this affect all pcs? Is it okay on the server itself? Does rebooting the router make a difference? Rather than reboot the server have you looked to see if any services have stopped that should be running? Also, is anything of interest in the system or application event logs? Please post back what you find. -- Brian Cryer www.cryer.co.uk/brian

Yes, web browsing does not work (http) and remote desktop connection does not work when I try to connect to the server remotely. We do not use the SBS as a proxy server... small office setup w/ 4 clients. All PC clients can't browse when this occurs as well as the server can't. And rebooting the router and modem has no effect. I'll look into the services and check the logs again, last time I looked all seemed ok but maybe I missed something (didn't think much of this till it occurred again). Taking it more seriously now. Thanks Brian... I'll post my findings.
