# "WARNING: Some or all identity references could not be translated" in the Client.log

*Applies to: Patch My PC Client*

## SYMPTOMS

Why do I see warnings like the following every 24 hours in the Patch My PC Client log (**C:\ProgramData\PatchMyPC\Logs\Client.log**):

`WARNING: Some or all identity references could not be translated.`\
`Exception: System.Security.Principal.IdentityNotMappedException: Some or all identity references could not be translated.`\
`at System.Security.Principal.SecurityIdentifier.Translate(IdentityReferenceCollection sourceSids, Type targetType, Boolean forceSuccess)`\
`at System.Security.Principal.SecurityIdentifier.Translate(Type targetType)`\
`at PatchMyPC.Agent.Modules.DeviceInventory.Providers.Windows.ComputedInventory.UserProfileProvider.GetAccountName(String sid) in D:\a\1\s\Modules\PatchMyPC.Agent.Modules.DeviceInventory\Providers\Windows\ComputedInventory\UserProfileProvider.cs:line 66 PatchMyPC.Agent.Modules.DeviceInventory, Version=1.0.50.19, Culture=neutral, PublicKeyToken=null 10/17/2025 8:28:42 AM 16 (0x0010)`\
`llationToken cancellationToken) in D:\a\1\s\Modules\PatchMyPC.Agent.Modules.StateManagement\Communicat`i`ons\WebApiStateChannel.cs:line 54`

## CAUSE

This issue can be caused by numerous factors, such as:

* Network problems
* Switching Intune tenants
* If the referenced account has been deleted from Active Directory/Entrad ID

It can also occur when we attempt to look up an account's "friendly" name (typically during inventory actions where we record user info, such as user apps, local groups, etc.).

If the account is not a local account and the device is using Active Directory, this involves a lookup to Active Directory to resolve the account SID to an account name. When that process fails due to a lack of permissions or network connectivity, then this error is output.

## RESOLUTION

This is a very uncommon scenario because most of the clients we service are not Active Directory joined because they are Intune devices.

Due to the various potential causes of this error, there is no one resolution other than checking for causes such as those detailed in the [Cause ](#cause)section.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.patchmypc.com/patch-my-pc-cloud/troubleshoot/client/warning-some-all-identity-references-translated.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
