If you are running IBM Cast Iron on Windows 8 or 8.1 and you get this error: Error while activating the activity. Exception: Address already in use: bind and you are scratching your head, try this:
Run cmd as administrator and type: net stop http. You should get a list like:
– SSDP Discovery
– Print Spooler
– etc etc.
Do you want to continue this operation? (Y/N) [N]:
Type Y and these services that interact with port 80 will shutdown.
Note that I had to run this a few times because BranchCache kept popping up and this was the culprit. It took hours of investigation to isolate it down to this but the joy of getting it working was worth it. Hope it helps save you a bit of time!
