OK, have been testing/looking at NIS2009
If you open Internet Settings under Smart Firewall you have Program control.
In program control you will see (naturally) there are entries for Symantec NIS. I had 3 entries.
I deleted these 3 entries and rebooted expecting NIS to put these back. They have however not reappeared.
Can anyone check what entries you have for NIS in program control i forgot to write the info down!. I am wondering why NIS2009 has not put these entries back in since program control is on/auto. I would have expected them to be required. Live update etc is all working as normal.
