We have a large mix of WTOS clients running 6.5.0_46 and 7.0_217.
A group of the Wyse clients was recently moved to a WDM server for management. All WNOS.INI configuration is the same – except we are using WDM instead of a legacy FTP server.
For unknown reasons, the Wyse WTOS clients no longer report their hostname to the DHCP server. When I look at the DHCP leases, the hostname field is blank. Other devices, Windows PCs, printers, etc. are still showing the hostname as provided by the client, but all Wyse TCs that have been moved to WDM do not appear to be providing their hostname to the DHCP Server at least time.
