Error UNABLE DOMAIN LOGON NAME

Hello,

We have an issue in CRM, when user tries to execute any actions, this message happens "UNABLE DOMAIN LOGON NAME" and there is no possible to works in any CRM section.

In order to solve, we change value for "AutoGroupManagement" value set to 1 (false) in the registry (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM) and restart CRM services from IIS.

But we don't know because it happens.

Do you have any idea what may be the reason for this error?

Thanks and best regards,

Mónica.
