Cannot Log In to CA Service Catalog

Symptom:

I cannot log in to a CA Service Catalog computer.

Solution:

Try the following:

Verify that your user name and password are valid.
Verify that CA Service Catalog services are running on the computer that you are trying to log in to.
Verify that no underscore character (_) appears in the CA Service Catalog computer name, if you are using Microsoft Internet Explorer to access CA Service Catalog. If an underscore appears in the computer name, do one of the following:
- Use Mozilla Firefox or Safari instead of Internet Explorer to access CA Service Catalog.
- Rename the computer to remove the underscore, and update all references to the computer name throughout your environment. Then continue to use Internet Explorer to access CA Service Catalog.
