VISA 0xBFFF0011 Network Instrument Connection Error

[Kenneth]

I found several topics addressing the VISA 0xBFFF0011 error.  I have a single calibration instrument attached (via RS-232) to a B&B ES1A adapter on the local network.  I originally wanted to use it as a COM port from a custom calibration routine.  However, two computers are calibrated simultaneously and I switched the 'driver' from B&B's RealPort (Virtual COM) to using TCP sockets. 

I built a test VI (as an EXE) to communicate with the instrument.  I tested on my dev PC, yesterday and it worked OK.  Today, I assigned a static IP to the adapter, so that it could be found by both targets on the local netwoork.  I copied the EXE to a target PC (#1) and it works okay there.  To test simultaneous access, I tried to run from my PC, but it returned the VISA error 0xbfff0011. 

The possible reason is:

ISA:  (Hex 0xBFFF0011) Insufficient location information or the device or resource is not present in the system.

Some of the topics that matched the error:

1. https://forums.ni.com/t5/LabVIEW/VISA-Hex-0xBFFF0011-Insufficient-location-information-or-the/m-p/69...

Describes a COM port issue with local computer, 2 pages.  Focused on fixing the problem via Device Manager and MAX. 

2. https://forums.ni.com/t5/LabVIEW/insufficient-location-information-when-communicating-with/m-p/70647...

Describes a TCP connection issue.   Issue resolved in that the network instrument was locked up. 

3. https://forums.ni.com/t5/LabVIEW/Error-Code-0xBFFF0011-Manual-TCPIP-Connect/m-p/1145259/highlight/tr...

Describes a similar network issue.  Issue was with instrument.  Inquiry into instruments, etc, but not resolved.

Things I have tried:

Target PC #1: Running Test program & communicating with network instrument

Development PC:

1. ping: ok

2. in MAX, change IP addresss (when changing from DHCP to static IP): test BSOD'd the dev PC

3. in MAX, Delete Network VISA resource

4. in DevMgmt.msc;

   found the device with its old IP address under Multi-Port Serial Adapters! => Uninstall it.

5. in MAX, Add Network VISA TCP/IP Resource

   Manual Entry of address, port

6. MAX reports the specified IP address as its 'name' and reports actual IP address = 'Unknown' (both PC's)

7. Stop program on Target PC #1; Run test program on Dev PC => <ERROR> on Dev PC

   > Restarting communication program on Target PC #1 works, still.

DEV PC: > Win 7 Pro; LV 2009 sp1; NI VISA 5.1.1; MAX 5.1

Target PC: > Win 7 Pro; LV 2009 sp1 Run-Time; NI VISA 4.6; MAX 4.6.2
