Firewall does not enable on the OfficeScan Agent

    • Updated:
    • 9 Jul 2018
    • Product/Version:
    • OfficeScan 11.0
    • OfficeScan XG
    • Platform:
    • N/A N/A

Even if the Firewall setting is enabled on the OSCE Server console, the Firewall is not turning on on the Agent's end. When you check the System Event Logs, you will get the following error:

Event ID: 7003
The OfficeScan NT Firewall service depends the following service: tmlwf. This service might not be installed.

When you check TmInstall.log, it shows that the TmLWF driver failed to install:

2017/05/16 15:36:10.113 2c14:22fc options: -i C:\Program Files (x86)\Trend Micro\OfficeScan
Client\tmlwf.inf Software\TrendMicro\NSC\PFW InfNameForLWF - tmlwfins.cpp(145)
2017/05/16 15:36:10.117 2c14:22fc DoInstall Start. - driversetup_lwf.cpp(180)
2017/05/16 15:36:10.865 2c14:22fc Install Failed (0x8004a029). - tmlwfins.cpp(210)

This problem may occur if the number of installed network filter drivers exceeds the specified limit. You need to check if the Network Filter Driver limit has been reached.

By default, Windows 7 has a limit of 8 and a maximum allowable limit of 14.

To resolve the issue, increase the Network Filter Driver limit so we can install the Firewall driver:

  1. Click Start > Run.
  2. Type "regedit" and then click OK.

    Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.
  3. Locate and then click the following registry subkey:


  4. On the right pane, right-click MaxNumFilters and then click Modify.
    If the registry key does not exist, manually create it.
  5. Select the Base Decimal option, change the value to decimal 14 then click OK.

    The default value is 8 and the maximum value is 14.
  6. Close the Registry Editor.
