I'm having a heck of time getting my home network going and it's for sure because of my firewall. Computer 1: Win7 32bit Home Premium - ESS5 is installed here Computer 2: Win7 64bit Professional - using MS Security essentials here I have shared the C: drive of Computer 1 to allow Everyone access. Theoretically anyway since currently it only works if I have my ESS5 Firewall off. I have found in the trusted zone (in ESS5, Setup -> Advanced Personal firewall setup -> Network -> Personal firewall -> Rules and Zones -> Zone and Rule editor -> Setup) that you can added a particular IP address as to be Trusted and therefore ignored by the firewall. However, since everytime Computer 2 gets restarted, I don't know what IP address it will be assigned. Is there a way to get an entire range trusted so that anything that gets plugged into my network is considered trusted? I have PS3 elsewhere in the house and it also is getting blocked when trying to access Computer 1. Thanks for any help - please be as detailed as possible in describing steps to fix, or let me know if more info is required from me (log files, etc). Thanks!
