I have been using Uniform Server successfully for about one year.  It's loaded on my Windows Vista laptop.  It works perfectly.   Recently, I had the need to install it on my Windows XP Pro system.  I can't get it to start up.   In the 'Server_Start.bat' line that brings up 'redirect.html', I see the the blue Uniform Server logo page perfectly.  But after one second, when it tries to refresh with 'http://localhost/apanel', I get the '404' error that the page wasn't found.   By modifying the 'Server_Start.bat' file so that it stops just after the 'redirect.html' line, I see that if I enter the URL 'http://localhost/apanel' into the browser, it can't find it.  And if I enter, instead, 'http://127.0.0.1/apanel', it can't find it, either.   The "w:\" drive appears to be alive and well.  But for whatever reason, 'localhost' and '127.0.0.1' are not found.     Facts:   (1)  Windows XP Pro   (2)  Have Norton Internet Security on the machine.  Turned off all its protection, but that didn't help.   (3)  I tried using the 'hosts' file from my Windows Vista system (where Uniform Server is working fine), but that didn't help.   (4)  I tried a few things I saw in this forum -- still doesn't recognize 'localhost' or '127.0.0.1'   Thank you, in advance, for any suggestions.
