If a DX client wants to delete all source servers, the specification says to omit the parameter ItemIdentifier.

How is this accomplished using the COM interface since all parameters must be supplied in COM?

COM clients should set the parameter dwCount to 0 (dwCount=0) to indicate that all source servers should be deleted.
