Desktop PC runing Vista Ultimate. Symantec NIS 2007 was installed before the upgrade to Vista. Two motnhs ago, upgraded Office 2003 to 2007.

Since a month ago, when I started my nightmare with Symantec Support, Outlook 2007 will suddenly stop SENDING/RECEIVE my POP accounts; Exchange (in the LAN) works fine. When this happens, the NIS and the Symantec Security Center icons are removed from the system tray. No telnet to mail servers on ports 25 or 110 is possible. All other internet access is fine. The only way to get it back for a while, is to manually luch NIS 2007. It will stay there for a while and disappear again around 2.5 minutes later.

Multiple unistall/reinstalls, disabled all StartUp and all non-Microsoft/Symanted servicee, same problem.

Yesterday, a Symantec Tech told me that because "NIS 2007 is a HOME product it is conflicting with my hardware firewall" and that I should better use just NAV 2007.

Just for the sake of my long troubleshooting journey, I installed NAV 2007. Now, I have no network connectivity at all and I can not ping anyone inside or outside of the LAN because it either produce a GENERAL FAILURE or PING FAILED; transmit error 1312 or something similar.

Is there anyone out there that can through some light on this one?
