Empower Enterprise or Workgroup

The LAC/E32 is not visible on the domain. To verify, go to add a node in Configure the System to see if the LAC/E32 is showing in the node list. If it is not, the customer needs to confirm that the LAC/E32 has been added properly into the same domain as Empower.
FIX or WORKAROUND
Turn on and/or restart the watersservice on the LAC/E32.
Add DCOM port 135 in the exception list of the firewall.
If the LAC/E32 was added into a new domain, remove and add the LAC/E32 node from and into Empower using Configuration Manager as an admin.
