Trouble with Ethernet-connected Keithley lab bench setup

My team has spent the last several months getting things sorted and finally have our lab bench more or less set up. Four Keithley instruments, connected to KickStart on a PC through a Netgear Ethernet switch, but still hitting snags. Some troubleshooting assistance would be helpful.

• DAQ6510 Data Acq Multimeter: Runs fine.
• 2260B-80-27 DC power supply: cannot get IP address assigned.
• 2260B-30-72 DC power supply: Gets IP address, but KickStart cannot see it even if the IP address is manually typed in.
• 2380-120-60 electronic load: plugged directly into the laptop by USB due to lacking an Ethernet port, appears in device manager but is not found by KickStart.

Have installed the Keithley I/O Layer C10 and the IVI-COM/IVI-C driver for the 2380.

For the 2380 load, the only application of KickStart that recognizes the load is the Battery app.  That is an extra license (not included in -SUITE).
It can control the load for generating a battery model.

The 2260B may only be recognized by KickStart when using the USB-CDC interface not the LAN.
