[LDM #WVX-983889]: ldmping failing



Greg,

The firewall rules on the LDM servers must be configured to allow incoming TCP 
connections to port 388 from any port *and* allow bi-directional traffic on 
such connections. Sounds like your rules either don't allow such connections or 
only allow one-way traffic.

I've BCC'ed our systems administrator in case he has something to add.
