NIS 2010 icon disappears from system tray and NIS uistub dos not run

Recently I have had to reinstall NIS 2010 3 times because it stopped working.  Used Norton Removal Tool to uninstall.  SYmtoms are:

 

1. NIS icon disappears from system tray after boot.

2. Clisking on the NIS icon on the destop will not run uistub.exe

3. running uistub directly will not work either.

4 reinstall works for a couple of days then quits.

 

I am running Windows XP SP3 with all the latest updates.  I have completely removed and disabled uPnP and disabled the following services:

 

SSDP discovery service

Universal plu and play device host

 

Anyone have any other ideas?  Does Norton have a fix or are they even looking into this problem.  I have seen other posts that discuss same problem.
