To check for out-of-use InTrust servers:
1. Use the SQL Server management tool to open the dbo.ADCServer table in the InTrust configuration database.
2. Review the values in the LastServerPing and Status fields to identify the NAME of the InTrust servers that are not in use anymore.
When you have determined which servers should be removed, uninstall the InTrust Server and all its components directly from those computers using the Programs and Features tool from the Control Panel.
If this fails or is not possible to be done for some reason (for example, due to a corrupted InTrust Server installation or hardware failure), use the "adcremoveserver.exe" command-line utility to clear all configuration data for the out-of-use servers. For that, run this utility on an InTrust server different from the ones you are going to remove. The utility is located in the <InTrust installation folder>\ADC\SupportTools folder. The syntax is as follows:
adcremoveserver.exe <server_name>
