Like the title says, I've got a Dell M6600, running Windows 7, that connects to the network just fine, I can use it to browse the web, including https://officesetup.getmicrosoftkey.com/, I can connect to it via RDP, it was joined to the domain (more below), no noticeable slowness in the network connection. The issue is that the active networks are reporting Access Type: No internet access, and I can't connect to some things, like I can't activate Office 2013 because "We are unable to connect right now. Please check your network and try again later". No software firewall is enabled.
Here's what I've tried:
ipconfig release & ipconfig renew
- run
netsh int ip reset c:\temp\resetlog.txt
(the log never gets generated) - Connect with Wired Ethernet only
- Connect with WiFi only
- Uninstall/reinstall the network adapters using the management console
- Wade through a swath of unhelpful google results like
route delete 0.0.0.0 if 11
- Attempt a domain rejoin, got as far as removing the computer from the domain, but can't readd, as "The network location cannot be reached" (I can still RDP to it at this point using local creds, there are gpupdate failure events that should've told me this would fail)
- Check NCSI issues: navigation to http://www.msftncsi.com/ncsi.txt in IE results in a page with the text: "Microsoft NCSI", dns.msftncsi.com resolves correctly
- Pinging the DNS server results in request timed out, but performing nslookup works just fine using said DNS server.
- changed the IP address of the DHCP reservation to a known unused IP address to check for IP address conflicts
- uninstalled AV software
- changing switch port, switch for wired access had no effect, Dynamic Address Tables correctly updated when switched to a different port (the ports on the switches have the same configurations for most of the other successfully communicating computers on the network)
- pinging DNS server works now, was failing, even though it was working fine with nslookup when pinging
