OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc Namespace > ServerDescriptor Class > ServerDescriptor Constructor : ServerDescriptor Constructor(String,Guid)
Name of the machine. Determines the computer on which the OPC server is located. It may be an empty string, in which case the OPC server is assumed to exist on the local computer or at the computer specified for it by DCOM configuration.

The value represents a UNC or DNS computer name. Any string can be passed to this parameter (i.e. will not cause System.ArgumentException), but not all values make sense and will work when an operation using them is attempted. IPv6 addresses are normally enclosed between '[' and ']'.

The value of this parameter cannot be null (Nothing in Visual Basic).

The CLSID associated with the object to be created.
Initializes a new instance of the class, with specified machine name and object CLSID.
