are you getting this error on my windows IIS, ii you have a default.asp page in my wwwroot folder.

An error occurred on the server when processing the URL. Please contact the system administrator.

If you are the system administrator please click here to find out more about this error.

how to fix this error.

you might be getting this error if you have windows 2008 server.

what does this error mean: basically, this is just a default error that IIS is showing, it doesnt mean anything, well, at least it doesnt mean the real error, this is for security reasons. so everytime you get an error on your .ASP pages, this error will show up, so it doesn't tell you what is really wrong with the script. this is a security feature if you are running a public website on the internet.

if you are familiar with PHP, in php you can configure it so it wont show the errors, well, this is the same, except that windows shows this default message, you can create your message also if you want to.

so if you are getting this error message on your server, you will need to configure it so that it shows the real error on your script. i will be using windows 7, fist access the computer management tool in windows

to access computer management tool go to Start then righ click on "My Computer" and select "Manage"

- then click Apply under Actions [Actions is the menu on the right]

now refresh your browser and you should see the real error. for example, mine says:

Microsoft VBScript compilation error '800a0401'

Expected end of statement

/Default.asp, line 4

response.write("Link: " & request.querystring("link"));
