My laptop originally had Windows 8 (which had been updated to 8.1 and the spring update) and I had Suitcase installed with no problems. Today I blew away the whole machine and installed a clean copy of Windows 8.1 Pro. Everything was humming away just fine till I installed Suitcase. After the reboot the laptop could still access the local LAN just fine, but wouldn’t access anything beyond the router. Flashing back to a restore point before installation resolved the issue.
I have since installed Suitcase 3 times and restored 3 different previous states, each time with the same result. Once it didn’t block access till the 3rd reboot after install, and once I got access back briefly by shutting down Bonjour. Is Bonjour really necessary on a single machine install?? I remember it causing problems years ago.
