[Samba] no Access to network share after login until restart of smbd

[L.P.H. van Belle]

Hai


now it has something todo with caching somewhere, i dont know why. 

But wait... yesterday/today is windows update day..
the day i always start with windows problem. 

 

Few tips. 
i noticed here in the office, laptops and pc had hybernation enabled

 out of the blue... (thanks MS, again).. 


Just try reboot the computer. Dont shutdown.. reboot.
not working, remove all shares (disconnect) then reboot. 



And if that does not work.
! in all cases, remove the drivemapping.. 
Create a new policy. 

make sure this is applied before the drive mappings. 

remove all mapping with it. ( after its all fixed, disable it )

Try this, use login format : username at REALM.TLD

or if you normaly use ADDOM\username .. try with only username 

i hope it helps you.. 

Greetz, 

 

Louis
