| Debugging Tools for Windows |
The !ndiskd.dbglevel extension sets the NDIS debug level.
Only one level can be selected. The following levels are possible:
| Value | Meaning |
| INFO | All available debug information is traced. This is the highest level of tracing possible. |
| LOG | Log information is traced. |
| WARN | Warnings and errors are traced. |
| ERR | Errors are traced. |
| FATAL | Only fatal errors, which can cause the operating system to crash, are traced. This is the lowest level of tracing possible. |
| Windows 2000 | Ndiskd.dll |
| Windows XP | Ndiskd.dll |
| Windows Vista and later | Ndiskd.dll |
