If the problem does not appear on the same host, the problem lies between the 
ESX hosts or the net infra.

Nope, that's not it.  After moving it to the same ESX host as the other server, 
you can reboot either and not see this behavior.  It worked in the past (when 
it could reach the EMS box) while on separate ESX hosts.
 
IGMP Multicast mode FTW!!!
 
Nah... not really... seriously, I keep them in Unicast mode.
 
I will be taking NLB out of the picture, though; will put them behind a pair of 
F5 load balancers in the future.

Does ESX support cross-host NLB?
What NLB mode (unicast/multicast) are you using?
Have you tried switching between modes to see how things shake out?
