VMware – {hostname} could not reach isolation address: none specified


KB ID 0000445 Dtd 13/05/11


Seen on vSphere:

could not reach isolation address

Error Host {hostname} could not reach isolation address:none specified.


1. In my case the host did NOT have a default gateway, (this had occurred because the subnet mask of the server had been entered incorrectly when the server was built. So the default gateway appeared to be on a different network).

2. With the offending host selected, Configuration > DNS and Routing > Properties > Routing > Put in the correct default gateway > OK.

esx set default gateway
