In my Distributed SpectroSERVER (DSS) environment, the Spectrum Control Panel "Select Host Machine" dialogue, lists incorrect hosts. These extraneous entries do not show up in the landscape map and are not visible on any SpectroSERVERs in the DSS.
The $SPECROOT/SS-Tools/HostUpdate command can be used to view the Location Server cache by entering the following command
HostUpdate can also be used to remove entries from the cache by entering the following command where <HOSTNAME/IP> is either the hostname or the ip address of the entry to be removed:
./HostUpdate -r <HOSTNAME/IP>
