Challenging Multi-player Server Issue

We are experiencing an issue with running a MultiPlayer server. If we run our map in singleplayer mode everything loads properly. However if we set up a server (dedicated or not) running the same code, the server starts up but we see the following in the console log when any client tries to connect:

Mapping string: MissionStartPhase1 to index: 8
Entering clientCmdMissionStartPhase1(1, control/data/maps/newMission.mis, lush)
*** New Mission: control/data/maps/newMission.mis
*** Phase 1: Download Datablocks & Targets
Leaving clientCmdMissionStartPhase1() - return
Entering onDataBlockObjectReceived(0, 11)
Leaving onDataBlockObjectReceived() - return

Oddly, since it is the same code that works in single player, we are a bit perplexed as to why we would be getting a particle texture error when connecting to a multiplayer server.

I'd appreciate if anyone can shed some light on this.

Thanks.
