I am trying to fix very old CRM 2011 environment. It doesn't at least from 2017.
CRM Server: CRMVersion: 5.0.9900.1060/ CRM 2011 Rollup 13, Windows Server 2012R2, no ADFS.
On the CRM Server I enabled tracing and in CrmAsyncService log I get error messages:
System.Security.Authentication.AuthenticationException: The user name or password is incorrect.
System.Runtime.InteropServices.COMException: The user name or password is incorrect.
MSCRMAsyncService, MSCRMAsyncService$maintenance, MSCRMUnzipService, MSCRMSandboxService
Using dedicated account:
- I can log in by the account to windows without issues,
- the account is included in the CRM Server and SQL server Local Admin groups,
- the account has granted SQL DB rights to CRM DB and CRM Config DB.
