When the OSCE server is located in an isolated network enviroment, the DLP agent is unable to deploy to agents. In the filelist, there is no DLP package or DLP SDK DLL in the DLPlite folder on the client's side. Upon checking tmudmp.txt, it shows the following:

524, 525, and 526 are DLP-related Active Update Identifiers (AUIDs). Since the customer is in an isolated network, the OSCE server is unable to get them from Trend Micro Active Update (TMAU). Above, it shows that 524, 525, and 526 cannot be found and there is no need to update them.
