WinCC OLE DB provider problems

Hello ,
I have joined a standalone PC with WinCC running to Microsoft AD domain. After that I can't transfer archive data using WinCC OLE DB provider to Excel file. The problem is with login to SQL server database from WinCC OLE DB. In WinCC OLE DB provider properties I can't use windows login accounts (I have it in gray).

The only way to connect is setup a user and password. Before the changes the user was empty without password and all was ok. After moving the PC to domain it doesn't work. I have tested data transfer using Microsoft OLE DB and windows authentication.It works. Why WinCC OLE DB can't access the sql server tables using empty user and password after moving PC to domain ?
