Troubleshooting
Symptom: A user cannot be redirected to the specified URL server, no matter what URL the user enters
in the IE address bar.
Solution:
z If a user enters an IP address in a format other than the dotted decimal notation, the user may not
be redirected. This is related with the operating system used on the PC. In this case, the PC
considers the IP address string a name and tries to resolve the name. If the resolution fails, the PC
will access a specific website. Generally, this address is not in dotted decimal notation. As a result,
the PC cannot receive any ARP response and therefore cannot be redirected. To solve this
problem, the user needs to enter an IP address that is not in the free IP range in dotted decimal
notation.
z If a user enters an address in the free IP range, the user cannot be redirected. This is because the
switch considers that the user wants to access a host in the free IP range, unconcerned about
whether this PC exists or not. To solve this problem, the user needs to enter an address not in the
free IP range.
z Check that you have configured an IP address in the free IP range for the Web server and a correct
URL for redirection, and that the server provides Web services properly.
