Upon restarting one of two esxi hosts, some of the client machines can now only see host LAN not the physical one. These are windows server clients and if I add an additional VMware nic, the original one then works. On two VMware I have added this new card and in the guest os, swapped over the ip addressing and then in the client settings, deleted the original nic. For these all is well but for the last one, this workaround fails.
Note that in all cases, the NICs are set to see the whole network, not just host, and that none of the port groups have changed. Any ideas? Is there a way to simply reset the NICs on the machines to some factory default?
Any help much appreciated.
