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.
