WebISO Troubleshooting

Follow steps in this section if you experience problems authenticating at the WebISO login page.

Make sure you have configured your web browser properly.
If you have never changed your Andrew password or not changed it in a long time, change it now.
Check your computer’s clock to make sure your machine's time, time zone, and Daylight Savings Time (if applicable) are set properly for your geographic region.
Quit and restart your browser and try logging in again.

Following these four steps solves the majority of WebISO problems. If you are still having problems, continue reading the following:

Problem:
I can't log in to WebISO with my Andrew account; however, I can read my email and do other things with my Andrew account.
Solution:
Your Andrew account password has either never changed or hasn't been changed in a very long time. Changing your password may resolve this problem. For help with changing your password, read Managing Your Andrew Account and Password.

Problem:
I'm using a Linksys wireless AP router and can't get into WebISO.
Solution:
Make sure you have the latest router firmware installed.

Problem:
When I try logging into WebISO, I get the following error message:
Base64Decode error '800a0001'
Bad Base64 string.
/bin/n_libBase64.asp, line 45
Solution:
You may have a piece of spyware installed called "Commonname" which is interfering with your browser. Select Start > Control Panel > Add/Remove programs, remove "Commonname," and then restart your computer.

Problem:
I have two Andrew accounts and I can't access my Blackboard courses.
Solution: Contact the Computing Services Help Center 412-268-HELP (4357). We can merge the two accounts together. Changes may take a couple of days to be reflected in the Student Information System and in Blackboard which may cause interruption of access to your Blackboard courses.

Problem:
I am accessing WebISO from behind a firewall.
Solution:
Since every Intranet and firewall configuration is different and beyond our control, we are unable to provide technical assistance to users accessing WebISO server from behind a firewall. We can, however, provide basic information about the resources used by WebISO. Minimally, in order to use these services, the following traffic must be permitted for machines that you will be using in your organization:

Ports 80 (HTTP) and 443 (HTTPS) should be permitted for all machines in the CMU.EDU domain. There are many machines being utilized within the WebISO system, and more will be added in the future. Allowing HTTP and HTTPS traffic to pass to all machines within CMU.EDU will greatly reduce the potential for problems.
