FSLogix Codes and what they mean

Article
03/31/2023

The Profile and ODFC container set three values that represent the state of FSLogix for the user signing in:

Status
- Normal
- Error
Reason
Error (generated from Windows, not FSLogix)

The three values are stored for each user's session in the local machines registry. Depending on the container, the user's session information could be stored in one (1) of two (2) places.

Profile container: HKLM\Software\FSLogix\Profiles\Sessions\%sid%
ODFC container:
- HKLM\Software\Policies\FSLogix\ODFC\Sessions\%sid%
- HKCU\Software\FSLogix\ODFC\Sessions

Status and Reason codes provide a holistic view of the FSLogix state for any specific user. The Status code can be one (1) of two (2) types, normal and error. Error codes are set when an FSLogix operation didn't succeed. These codes are generated from Windows.

EXAMPLE: Status codes in Profile Logs

[07:31:26.900][tid:00000d30.00004c04][INFO]             Status set to 28: No user session config found
[07:38:15.311][tid:00000d30.0000218c][INFO]             Status set to 100: Waiting for the Windows Profile Service to determine the user's profile folder
[07:42:47.045][tid:00000d30.00004168][INFO]             Status set to 200: Setup in progress
[07:42:48.076][tid:00000d30.00004168][INFO]             Status set to 0: Success

Reason Codes

Reason codes are used to help clarify the normal Status codes as described and aren't used to with error Status codes.

Code	Description	Explanation
0	REASON_PROFILE_ATTACHED	The container is attached
1	REASON_NOT_IN_WHITE_LIST	User isn't a member of the include group
2	REASON_IN_BLACK_LIST	User is a member of the exclude group
3	REASON_LOCAL_PROFILE_EXISTS	A local profile for this user exists on this system
4	REASON_SHORT_SID	Not an appropriate user type
5	REASON_UNSET	Reason initialized to empty state
6	REASON_COMPONENT_NOT_ENABLED	Component isn't enabled in product key (legacy)
7	REASON_WINDOWS_TEMP_PROFILE	Profile is a Windows temporary profile
8	REASON_NOT_WVD_SESSION	Session isn't an Azure Virtual Desktop Session
9	REASON_FAILED_TO_LOAD_PROFILE	Profile load failed

EXAMPLE: Reason codes in Profile Logs

[07:26:39.015][tid:00000d30.000044b4][INFO]             Volume name: \\?\Volume{c04ba195-522c-40b8-a894-879025d9b386}\
[07:26:39.015][tid:00000d30.000044b4][INFO]             Reason set to 0: The container is attached
[07:26:39.015][tid:00000d30.000044b4][INFO]             queryFreeDiskSpace returning after 0 milliseconds

Error Codes

When an FSLogix operation fails, a Warning or Error code is set. The Warning and Error Codes come from Windows, where FSLogix made an API call and the operation wasn't successful. These codes correspond to System Error Codes.

EXAMPLE: Warning codes in profile logs

[07:31:01.428][tid:00000d30.00004c04][WARN: 00000005]  Error removing directory: \\fslfileserver\profiles\jdoe-S-1-2-34-000000000-000000000-0000000000-00000000-test (Access is denied.)

System Error Code troubleshooting

System Error Codes can be decoded in various ways. The following links describe the most common methods for investigating these codes and their meaning.
