Problem: Long login times at windows clients


Long login times at windows clients with roaming profiles.
Maybe also error messages like that. Windows bluescreen:

Fehler bei der Anmeldung des Diensts „Benutzerprofildienst“ Das Benutzerprofil kann nicht geladen werden.

eventlog likes this:




check if GPOs affect the login process negativly.

Check sysvol replication
samba-tool ntacl sysvolcheck

Check for Data in AppData/Roaming for Teams cache files, or browser cache files this Data can increase to lots of small files, which can slow down the login.

Also realy long UNC - Universal Naming Convention can interrupt the login.

Possible Solutions:

Repair sysvol synchronisation with:

samba-tool ntacl sysvolreset

Controll the result again with:

samba-tool ntacl sysvolcheck


  • Folder redirection: Redirection of the folder AppDat\Roaming, Dokumente, Desktop und Download.
  • The first login takes some time (15-20 minutes), the second login is significantly faster (1min 30 Sec).
  • Waiting for network during login
  • Remove the cache of chrome and FireFox after closing the browsers.
