   SVRSVCSETUP -SF_ConfigDLPForensic UploadForensicDataSizeLimitInMb 150
   SVRSVCSETUP -SF_ConfigDLPForensic RejectDownloadOnFileSizeInMb 150
   SVRSVCSETUP -SF_ConfigDLPForensic maxAllowedContentLength 200000000

Optionally, it is recommended to further configure the agent behavior. This is to avoid having too many connections with huge DLP forensic data upload, which can impact server capacity. Perform the following configuration:

1. Open {Apex One Server installation folder}\PCCSRV\ofcscan.ini using a text editor.
2. Go to the [Global Setting] section, and add the following keys:
   EnableConcurrentForensicUploadControl=1
   ConcurrentForensicUploadControlMinTriggerSizeInMB=20
3. Open {Apex One Server installation folder}\PCCSRV\Private\vdi.ini using a text editor.
4. Search for the [TaskController] section, and Add the following keys: Controller_04_MaxRunningSeconds=600
   Controller_04_MaxConcurrentGuests=10
   Controller_04_BaseWaitingTime=10
   Controller_04_MaxWaitingTime=300
   Controller_04_TaskName=DLPForensicUploadSecure
   Controller_04_SingleVirtualHostOnly=1
5. Login to the Apex One web console, the go to Agents > Global Settings.
6. Click Save to deploy this setting to agents.

Since Apex One server will send DLP forensic data to Apex Central server, it is necessary to change IIS and PHP settings on Apex Central server to accept large files from Apex One. Do the steps below:

1. Open IIS Manager on Apex Central server.
2. Select Apex Central web site. By default it is the "Default Web Site".
3. Double click Request Filtering.
4. Click Rules tab and click Edit Feature Settings on right panel.
5. Change Maximum allowed content length (Bytes) to 1024000000.
6. Open {Apex Central installation folder}\PHP\PHP.ini with text editor.
7. Find "Memory_limit" and "Post_max_size" and change it as following:
   Memory_limit=1024M
   Post_max_size=2000M
