Appendix B: Troubleshooting
Proceed with the following network checks:
 Check the user machine’s visibility to the domain controller from which
the logon script is being run.
 Make sure that NetBIOS is enabled on the machine.
 Make sure the user profile is not blocking the execution of the logon script.
Domain Controller Visibility
To determine is the domain controller is visible to the workstation:
 Attempt to map a drive on the client workstation to the domain
controller’s root shared drive. This is the drive from which the logon
script is normally run, and on which
LogonApp.exe resides.
 Run the following command from a Windows command prompt on the
workstation that is not being identified:
net view /domain:<domain name>
If either of these tests fails, see your Windows operating system
documentation for possible solutions. This is a network connectivity problem
and not a Websense issue.
NetBIOS
Make sure that NetBIOS for TCP/IP is enabled and that the TCP/IP NetBIOS
Helper service is running on the client machine. If either of these is not
running, the Websense logon script will not execute on the user machine.
The TCP/IP NetBIOS Helper service runs on Windows 2000, Windows XP,
Windows Server 2003, and Windows NT. In Windows 98, TCP/IP NetBIOS
is enabled by default.
If your network uses Active Directory, and if you have Windows 98 client
machines, go to the Microsoft website for assistance: www.microsoft.com/
windows2000/server/evaluation/news/bulletins/adextension.asp.
User Profile Issues
If the user profile on the local workstation is corrupt, it can prevent the
Websense logon script (as well as the Windows GPO settings) from running.
To eliminate this as a cause:
1. Log on to the workstation as a local administrator.
