thank you, I found that by accident when I found three objects in the network map for my wifes comp, I checked the properties of each & I found on the original (first created since i recognized the name) named , the IP (172.16.2.2) addy. then I used localhost & IP which u no didn't work, then I tried the IP and directory/administrator & I was in the back end of my joomla build.
sometime it is a small thing that stops all. thanks to all forumers for their help. I too will help when I know an answer
