Hi Jennifer,
After trying Taylor's suggestions, if you are still facing the same error, please try these steps:
1. Do not configure the TDOD service separately on your laptop. We will attempt connecting to the server where it is correctly configured.
2. On the "server" machine, make sure that the Service URL in the TDOD configuration editor reads something like http://COMPUTER_NAME:8090/GTService instead of http://localhost:8090/GTService.
3. Upgrade the Microsoft Silverlight version to the latest (on your laptop). You will be able to find your current version from "Control Panel" -> "Programs and Features" -> "Microsoft Silverlight" entry.
The latest version available for download is Build 5.1.41212.0. You may download it here: https://www.microsoft.com/getsilverlight/
4. After upgrading Silverlight, try a connection from your laptop web browser to the TDOD Service URL that has been set up on the server machine (which you are able to access fine from the server machine directly).
If you are still facing problems, please open a support ticket at https://support.ca.com and one of our Support Engineers will contact you directly to help.
Thanks,
Sameer
