internet access problems

Posted on 2006-05-08

I recently installed SBS on a computer, and am using that computer to share an internet connection between about 8 computers (going through a 16 port switch).  Initially, I decided not to join the computers to the domain, and simply created user accounts on the server that mirror those on the workstations.  Everything seemed to be working fine, until all of the computers were being used at the same time.  Randomly (or so it appeared), the server would cut all of the computers off from the internet as well as the shared folders on the server.  I can temporarily fix the problem by disabling and re-enabling the network connection to the local network, but this only allows about 5-10 more minutes of connectivity.  So, is this some sort of security feature in SBS that keeps non-joined computers out of the domain, and thus off of the internet, or is it more likely that there is a problem with the computer or configuration of SBS?

Thanks for any help.

    The fact that you can fix the problem by disabling and re-enabling the network connection seems to suggest that it may be an ethernet or IP problem rather than a problem with SBS security.

    When the connection fails can you still ping the server?  Can workstations still ping each other? Try these before and after the connection fails. Have you tried different ports on the switch?  If you can first resolve these basic connectivity issues, then we can look at other issues.

    Can you please post an IPCONFIG /ALL from both the server and a workstation?

    OK...I've since been told that the switch that I was using has had problems in the new switches and (knock on wood) haven't had any problems yet...thanks for your suggestions, though, I appreciate your time.
