• Digital signature failing to be verified issues.

  • All windows Error code: 0x800*****, -2146******,

    For example:

    Windows Error code: 0x80096005, 0x800b010a, 0x800b0110 etc.
    Windows Error code: -2146869243, -2146762486 etc.

  • Other error codes related with signature checking failure.
• OSCE’s own certificate file(public key file: OfcNTCer.dat) missing or mismatched issues.

1. "Set Log Path" to assign a log folder path, by default, it will be: C:\ _OSCE_IssueDetector\.
2. Turn ON OfcDebug using the Turn On/Off OfcDebug.ini button.
3. After turning On OfcDebug, you need to unload and reload the OSCE Agent to start writing debug log.
4. This tool will create C:\OfcDebug.ini to enable OSCE debug mode, and after reloading the OSCE agent, OSCE will write OfcDebug.log into the log folder that you set in Step 1.
5. Reproduce your OSCE agent problem/issue.

6. Click Detect Certificate Issue, then check the result in the Message Box and also check in ADT's own log file.

   It will analyze the OfcDebug.log generated under the log folder you set.

7. When an issue is detected, the issue description, possible root cause, and also the solutions will be in the output of this tool’s own log file (C:\Log_OSCEIssueDetector.log) as well as in the message box.
8. Currently the Detect Certificate Issue button only supports analyze ofcdebug.log file under the assigned log path.
9. Make sure to turn OFF OfcDebug.

• If Cert_001 or Cert_002 issue is detected, which means an OfcNTCer.dat (OSCE’s own certificate file) related issue, you can choose to fix it by using the tool.
• It will ask the user to unload agent first, then it will automatically copy the correct OfcNTCer.dat file from [\\%OSCE server% \ofcscan\Pccnt\Common\] folder to the local OSCE install folder for the user, then ask user to reload the agent.
• If SMB access to \\%OSCE server%\ requires a user name and password login from local, you first need to log in using Windows Explorer.
• If \\%OSCE server%\ can directly be opened via Windows Explorer without prompting a login dialog, this tool can directly copy the public key file to local.
• Only for OfcNtCer.dat file related issues will this tool try to do some fix.

• As for other issues, possible solutions and root cause will be in the output of both message box and in the following log file:

  C:\Log_OSCEIssueDetector.log

If you have an existing ofcdebug.log on hand (may be collected by CDT tool), and you want to analyze it using the Detect Certificate Issue button.

1. Place the ofcdebug.log file into the %LogPath% folder:

    

   %LogPath% is the folder you set using button "Set Log Path", by default, it will be C:\_OSCE_IssueDetector\.
2. Click Detect Certificate Issue.

When an issue is detected by the Detect Certificate Issue function, hitted logs will be the output in this tool’s own log. The “hitted log” means which log lines in the OSCE debug log indicate the issue.

So you can check “hitted log” to see which file signature failed to be verified. For example:

• It depends on the IssueDetector.ptn file that should exist under the same folder as this tool.
• .NET framework 3.5+ version

• If the OfcDebug.log file is very big, it may be a bit slow to respond after clicking the button.

  If the log file “OfcDebug.log” file is too huge, this tool may NOT be able to analyze it successfully or quickly, due to lack of enough free memory or other system resource.

  After turning ON ofcDebug.ini, click Detect Certificate Issue button to analyze the log file without waiting too long and to keep the log file from getting too big.

• After the OfcDebug debug mode is turned ON, OSCE's log server will drop 5 files under C:\ for debug purposes, which will the same effect if you manually create C:\ofcdebug.ini:

  The 5 files are:

  • 7z.dll
  • 7z.exe
  • LogServer.exe
  • OfcPIPC.dll
  • tmdbg20.dll

  After OfcDebug is turned OFF, these 5 files will remain under C:\. You may manually delete them if they are no longer needed.

• Supported OSCE versions:

  10.6 *, 11 *, 12 *

• Supported Platforms:

  All Windows platforms the OSCE Agent Program supports

• The tool does not need installation.
• The tool will not get installed in your system and may be deleted anytime.

• Changes To The System:

  • It only writes a registry key on the following registry:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\OSCE_IssueDetector
    "LogPath"=

  • A log file under C:\ :

    Log_OSCEIssueDetector.log

  • You can remove them manually after troubleshooting is done.
