Setupapi.log - very useful

To debug driver installations setupapi.log is very useful. Its present in WINNT folder.

If any probs in NDIS driver installations at site, i ask support engineers to increase loglevel of setupapi and request the logs. Its easy to narrow down the issue.

To increase loglevel of setupapi.log
1. If the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup registry subkey does not contain a LogLevel entry, create one as a new REG_DWORD value.
2. Set the value of the LogLevel entry to the 0x2000FFFF.
