The entry in the server0.log file shows that the OfficeScan Server plugin is unable to obtain the password to log in to the IDF web console. The password and user ID is usually stored under the following registry key:

[HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\OfficeScan\Addon\IDF]
"IDFPASS"=""
"IDFUSER"="Administrator"

If one of the two registry key is missing, please do the following:

1. Re-create the missing registry keys manually.

   1. Open the Registry Editor.

       

      Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.
   2. Go to [HKEY_LOCAL_MACHINE]\SOFTWARE\Trend Micro\OfficeScan\Addon\IDF.

   3. Manually add a New String Value for the following:

      IDFPASS: Your own password
      IDFUSER: Administrator

2. Go to the command line and run the following commands under Intrusion Defense Firewall directory: 

   idf_c.exe -action unlockout -username USERNAME -newpassword NEWPASSWORD

   This will reset the password for the administrator user account. Make sure that the password matches the one specified in the registry key.

3. Restart the following services:

   • OfficeScan Plug-in Manager service (along with Intrusion Defense Firewall service).
   • IIS Admin Service or Apache Service
4. Log in to the web console and verify if login is now successful.
