What is agent blacklisting?
When computer X merges into computer Y then X gets put into the AgentBlacklist table and it (computer X) disappears as a resource in the SMP Console. However the Sym Agent still has GUID X and thinks it is allright. The AgentBlacklist table tells the Notification Server (NS) which computers are not allowed to receive policies and whose NSEs (X, for example) should not be processed.

to the agent which means that the Sym Agent should change its GUID. The Sym Agent then is supposed to call Createresource.aspx which would return the new GUID Z.Note: In cases where the merge was automatic (X was merged into Y due to equal resource keys) Z = Y, then we will have 2 machines sharing the same GUID. The ONLY workaround in such cases is to make sure all the resource keys are unique for the problematic pair of computers. This is not always possible.
Manual Blacklisting
There are 2 filters that are supposed to be managed by users manually. The purpose of these filters is to tell the NS what computers should stop receiving policies - all policies or user-based policies. The use-cases for maintenance of these filters are undefined. However here is what they technically do:
Both filters are regular filters, so they may contain either explicit resources or be query-based.
