Issue/Introduction

When the Sym Agents with a blacklisted GUID are requesting a policy and attempting to save a messaging resource an error similar to the following is seen:

GUID ... has been blocked by the Host Resource Blacklist.

Environment

ITMS 8.x

Resolution

Remove the GUID from the  AgentBlacklist table if the process was unable to get the new GUID sent out to the Sym Agent.

The following SQL query will delete the machines from the AgentBlacklist tables that are actively trying to communicate with the Notification Server:

delete from AgentBlacklist 
where Guid in
  (
     select c.Guid
     from AgentBlacklist ab
     join Evt_NS_Client_Config_Request ccr on ccr.ResourceGuid = ab.Guid
     join vRM_Computer_Item c on c.Guid = ccr.ResourceGuid
     where ccr.StartTime > GETDATE () - 7
     group by c.Guid
     having COUNT (ccr.ResourceGuid) > 5
  )

If errors regarding the ResourceMerge table begin to appear in the logs after the above query is run then the following SQL query may need to be run as well:

delete from ResourceMerge 
where OldResourceGuid in
 (
  select vc.Guid
  from ResourceMerge rm
  join vRM_Computer_Item vc on vc.Guid = rm.OldResourceGuid
 )
