I'm trying to set up and run SBS 2003 on my local network, which consists of only 3 or 4 computers apart from the one SBS is running on. At one point, after installing SBS for the first time, everything was working fine, and I was continuing to make changes to settings. Apparently I did something at some point, and now SBS can't connect to anything.
I have a D-Link router at 192.168.0.1. I have my main machine at 192.168.0.101. SBS is set up currently at 192.168.0.165 -- that IP address is explicitly set (not DHCP). SBS can't ping 192.168.0.1 or 192.168.0.101, or any other local computer -- but it CAN ping itself, by the IP address or the computer name, or localhost. It also can't ping anything on the internet, by hostname nor IP.
The other weird thing is that I can ping SBS either by hostname or by IP from my other local machines -- and I can also use Remote Desktop, etc. So everything else knows where SBS is -- which I would think means it's on the network just fine -- but SBS can't see anything else.
I don't know if it has to do with something simple in the domain setup, or if it's only seeing machines in its domain, or if it's something else in Active Directory, or what. Any help would be greatly appreciated. This is driving me nuts.
