How do I debug roaming profiles?

A. It is possible to create a log file of all roaming profile transactions using the checked version of userenv.dll. The checked version of the UserEnv.dll is the same dynamic link library (.dll) as the retail version, except that it contains debug flags that you can set and use with the kernel debugger. This file, which is included in both the Windows NT Device Driver Kit (DDK) and the Windows NT Software Development Kit (SDK)

A log file of the roaming profile transactions will be written to userenv.log to the root of the C: drive. Below is an profile log.
