I have installed TMG 2010 and it was working fine. After electricity went off and restart my PC again then Internet stopped working. The scene is after booting windows when it loads my Internal LAN then TMG stopped and nothing works like "Can't ping internal
or external modem" but if I disable internal LAN then my internet starts working on Localhost. I just restore my backup and everything back to normal. My question is why is this happening? I had these type of issues earlier couple of times and again
I had to restore my backup. Why is it happening? My TMG is not a member of domain, Can you guide me what should I do if I face this problem again? Thanks a lot in advance and if you don't understand you can ask as many questions as you want :)
When the issue happened, you may run TMG BPA to check if there is error message. and you may also check the error message in the event viewer. Meanwhile, please update all the NIC drivers and see if it helps.
