USS RealTime Server.  I'm using OPC to talk to the server.  In the united states I have no problems with the server, or I should say our app works fine with all installations where are stateside.  We recently installed in Australia and we are getting errors when trying to add items to the OPC group. We are are using the Fisher ROC Device, and the errors I'm getting are from items I'm getting out of the browse.

Error with OPC Configuration, unable to continue - WH20_ROC.ROC.BATTERY_VOLTAGE Exception from HRESULT: 0xC004800C.

Error with OPC Configuration, unable to continue - read:WH20_ROC.$DiagReset The parameter is incorrect.

any idea's, or anything you have seen in the past with locale's outside the united states using demand polling?
