Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk. 1. Edit Registry for each service. 2. Set Parameters/LogFileTruncateSize to 0xffffffff. Method 2 -------- 1. Force the registry to write correct value into Parameters/LogFileTruncateSize through InetMgr. 2.
