Please refer to this blog post for additional information.Hi, When I attempt to rename, drop, or anything DDL related to a particular table the query just hangs. This PowerShell script uses two queries from this blog post. This should help you understand why the block is happening. In the CSV files, you should be able to see the last queries of the sessions involved in the block, their isolation level, if they are inside a transaction and the locks they are holding. $DataSet.Tables | Export-Csv -Delimiter ' ' -Path "$OuputFolder\test_connection_$(get-date -f yyyy-MM-dd-HH.mm.ss).csv" -NoTypeInformation $DataSet.Tables | Export-Csv -Delimiter ' ' -Path "$OuputFolder\lock_list_$(get-date -f yyyy-MM-dd-HH.mm.ss).csv" -NoTypeInformation
