Start: 0900
0935: going along swimmingly,
Some odd error message in a Command window:
"The Service Name is Invalid"
then it closed and went away -- this error appeared on every install.
0940: "C:\inetpub\Solarwinds could not be modified (error from Configuration Wizard)
Ran it agin
Same error
Rebooted the App server
Config wizard worked this time 
Except it FAILED to build a web-request to the https port -- really does anyone actually test https bindings?
0952: started the additional poller installs
1029: started app2 upgrade (primary server in the FOE pair)
1100: started the addiitional poller upgrades
- these seemed to require more reboots of a server than I expected.
1143: all upgrades finished.
12:00 the informationservicev3 on two of the additional pollers (primary in a FOE pair) was crashing periodically
12:15 noticed the firewall settings for RabbotMQ were incorrect (need to have the ALL profile active, because the profile they were configured on was not active)
Also noticed the RabbitMQ port in the manual was incorrect (it says TCP/5671, it's actually on TCP 5672)
messed around trying various things; the secondary pollers in the FOE pairs are working fine so
Opened a support case
Started gathering diagnostics
failed over to the secondary and went for a lunch
1300: ate a slice of pizza and thought about this while reading the paper
1330: uninstalled all of the Solarwinds Components on the two servers; rebooted them; reinstalled everything and ran the config wizard;
1430: all working OK; Solarwinds support haven't called me back (I'll close the cases out shortly)
1530: wrote this up
