Hi Sarah,
There are a few things that I would check:
Have a look at the windows services. Control panel --> administrative
tools --> services and check that the Bruker flexlm server, Bruker tftp, Bruker
DHCP, and bfs services are all running. When you reconnected everything,
did you hit the red button on the ccu to reboot it and re-establish communication?
Did the ccu boot normally--if you watch the lights on the front of it, does it
go through the normal pattern?
Cheers,Mike

Hi all,
I am reading through old threads and trying to see if I can figure out what's going
on with our update to Windows 11 and Topspin 3.2 for an AVII system (2006). We were
previously running ok on Windows 7 with Topspin 3.1 but are being forced to upgrade
the hardware/OS. (My pleas of "don't mess with things that are working" went unheeded.)
The old computer did not have RS232 connection and it seems like we were able to achieve
everything through ethernet for 15 years, so I haven't pursued RS232 to USB adapter.
I haven't ventured down the VM route yet although that solution seems to work for many.
I have installed the OpenText NT toolkit and Topspin 3.2. I have flexlm running. I have
restored the previous spectrometer configuration with nmr_save / nmr_restore. I am able
to ping 149.236.99.89 without issue.
cf connects to the DRU and then hangs/errors at iiconf: connect to CCU. "connection to
spect (aqport0) failed unable to connect to remote hose (Unknown error) ('startd' demon
active on CCU ?)"
Any guidance would be appreciated. (Help me Sameer, you're my only hope, etc) :) This is
my oldest console but I have four more to go after this, unless I walk into the sea first.
Cheers,
Sarah
