I've got some problems with sharing internet between two 7 systems. I'll let you know how things worked before the new installs.
I use crossed ethernet cable with an ethernet network card. Before I had XP running as the host with a bridged connection and then a Vista system using the internet from the XP system. All that was needed then is to make sure the internet connection is shared on the XP host system and the internet would be shared without any problems.
I now have both systems running 7 and have tried to bridge the connections the same way I did before to share the internet but it won't work as ICS won't start and I can't find any box to tick to share the internet on the host in any of the network adapter properties or configirations. I can share folders but no internet.
I've tried troubleshooting, shutting down both PC's and unplugging the modem for 10 minutes and rebooting to no avail.
I've also tried to start ICS in task manager and in services but it won't run, it says when trying to start it in services:
The ICS on local computer started and stopped. Some services stop automaticly if they are not in use by another service or program.
I have all network discovery and sharing all turned on both computers.
