34980A on LAN: invisible to Benchlink Pro

Dunno whether anybody else has encountered problems with Benchlink Pro finding instruments on LAN:

My problem: trying to get the 34980A DMM to talk to Benchlink Pro thru more than just USB connection.

1- IO Libraries 15.5 Connection Expert discovers and enumerates the 34980A okay when connected via USB.
2- Benchlink Pro discovers and connects to 34980A through USB interface.
3- Connection Expert discovers and enumerates the 34980A okay when connected via LAN; can access 34980A thru its web-server interface.
BUT:
4- Benchlink Pro can't discover or connect to 34980A through LAN interface.

A dump from the BP find log reads:
12. Searching GPIB stopped due to error
11. Error occurred on GPIB. Message is (Expression does not match any devices.)
10. Searching GPIB
9. Searching USB stopped due to error
8. Error occurred on USB. Message is (Expression does not match any devices.)
7. Searching USB
6. Searching LAN stopped due to error
5. Error occurred on LAN. Message is (Expression does not match any devices.)
4. Searching LAN
3. Searching GPIB stopped due to error
2. Error occurred on GPIB. Message is (Expression does not match any devices.)
1. Searching GPIB

Yet when I turn around and plug 34980A back in via USB, everything's fine again and BP can find & use it.

Agilent Support is taking their sweet time getting back to me about this. Any ideas or suggestions?
