Hello Telecomvn,
I guess that in your case you probably want to use an html page to redirect the users to the long winded url easily.
Here's an example on how to do this very easily:
<html>
<head>
<meta http-equiv="refresh" content="0; URL=http://NSserver/Altiris/console/?mainUrl=%2faltiris%2fconsole%2fItemPage.aspx%3fItemGuid%3d94f31ff6-347e-4765-864d-20d1dde87ad9">
</head>
<body />
</html>
Now save the file as 'default.htm' under an easy to remember web-directory (for example /Reports/ which would be created under '\inetpub\wwwroot').
Then when your user navigate to http://NSServer/Reports they would go to the report page you created. If you want to have many reports you can put a redirect file with the proper name under the report folder etc.
