I recently installed NIS ver. 20.2.0.19 on an XP machine. NIS works fine until I log out and go on standby. When i log back on, the NIS icon fails to appear on the taskbar. If I restart, it comes back. I have used the Norton uninstall/install utility twice, to no avail. Also have installed this on two other machines, one XP one Mac/Paralells XP with no problems.
