We've got a few machines at a couple different clients that have the windows networking systray exclamation mark indicating limited network connectivity. The supposed error is "no internet access", though the internet works fine in every case. It is a very visible issue generating a lot of complaints, and the clients have a tendency to associate it with all kinds of other unrelated problems.
To clarify:
- Not all machines have the icon
- Problem machines all have the same basic setup as non-problem machines
- Some problem machines are win8, some win7
- They don't share common hardware specs
I have tried several things, including: reset ip stack, give manual ip settings to network adapter, disable ipv6, disable/re-enable adapter, all without success.
I don't know where to go to troubleshoot this. Is there a log with this info? Is the network connectivity check process well documented somewhere?
