ARP drops and returns? - intermittent connectivity

We have a Windows machine that is joined to 3 ZT networks. We can start pings and after some time one of the ZT network GW’s appears to fall out of ARP, pings fail, then after a bit it will return on it’s own…or we can cancel the ping, restart and the ping will be successful again for a while.
Is there a limit to ZT networks a Windows client can join?

No, a typical Windows computer can join and participate in more than three ZeroTier networks.

Try reproducing the client configuration on a clean Windows host, and/or doing a semi-hard networking reset on the affected computer:

> netsh winsock reset
> netsh int ip reset

BTW, your screenshot is compressed and unreadable.

The local site has identified a core router issue, we believe this is the culprit. Thanks for the info on the networking reset. We’ll continue to troubleshoot after hardware replacement. As for screenshot, interesting…shows up clear on the post when I load the page…??
