Troubleshooting RAS with Device and PPP logs

By Paul Anderson / October 3, 2016 — Network Services

Two files can be used to troubleshoot RAS problems: device.log and ppp.log. These files need to be enabled in the registry.

For device.log, set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters\Logging to 1. (default is 0) This will show you the communication between the server and the modem.

For ppp.log, set
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\Logging to 1. (default is 0) This will help you debug the ppp connection and includes all failed attempts.

Both files will be created in \<winnt_root>\system32\ras.
