These are the parameters I specify to use the vWorkspace broker.
VDIBroker=NameorIPofBrokerServer:8080
ConnectionBroker=Default IgnoreProfile=yes
SignOn=Yes EnableOK=Yes DisableGuest=yes LastUsername=No
DomainList=yourdomainhere
AutoSignoff=yes
Note that using the “VDIBoker=” parameter in your wnos.ini file you are only able to specify one broker server.
