When performing a discovery the above error appears on the PowerConvert Server. In addition the discovery job will fail at 50 percent.
Solution:1 Confirm IIS and NTFS Permissions on the PlateSpin Server
Step 1: Confirm the IIS and NTFS Permissions are set as stated in KB Q20718
Solution:2 Modify the System Wide .NET machine.config to include your proxy server
Step 1: Open My Computer and navigate to <WINDOWS>\Microsoft.NET\Framework\v2.0.50727\CONFIG
Step 2: Locate the machine.config file and open it with notepad
Step 3: Add the following lines somewhere within the body of the configuration file
usesystemdefault = "false"
Step 4: Restart IIS on the PlateSpin Server.
This will resolve the 401: Unauthorized error message as this changes the system wide .NET 2.0 Configuration to not use the systems default proxy. This can be an issue if a proxy server requires authentication and the PlateSpin Server is not able to authenticate to the server.
