This may be a dumb question, but does TCP/IP need to be bound to a network adapter in Windows 2000 if you are only using dialup? I am troubleshooting a friend's computer and he has just upgraded from Win98SE to Win2K Pro. In doing so, we had problems getting his modem working right. We got that seemingly working, but now we can't browse the internet. At first, we couldn't even ping, it would say "unknown" host pinging by name and I didn't know any IP addresses of any websites off the top of my head.
So then, I went into the settings for the dialup connectoid and found that only tcp/ip was installed for networking components. So I installed Client for Microsoft Networks, restarted, now when we ping, the names resolve to Ip address, but we still get "Request Timed Out". I tried pinging the default gateway (got that from ipconfig /all) and that was successful. But tried pinging the DNS server and that failed (both of them).
So, I am thinking this sounds like a winsock problem, hence my earlier post about trying to find WinsockXPFix, in which that question was answered.
So back to my question. I ask this because I tried to do a release and renew of the Ip address while connected, but it says that TCP/IP is not bound to a network adapter. I know that in Win9x, TCP/IP does get bound to all adapters, dialup or nic. But I am thinking this is not the case in Win2k and that TCP/IP is only bound when on a LAN connection.
