I’ve had a very long standing problem where mapped drives on Windows PC are shown as disconnected after a PC wakes from sleep or after a reboot. Clicking to open the drive results in a delay of several seconds and then the share opens. I had this problem with Windows 7 right through to Windows 10 1909. Oggi, thanks to a different issue, Ho finalmente rotto che.

The problem is caused by Microsoft’s out-dated NetBIOS name resolution system. Io (come la maggior parte delle persone) map drives to the name of the target server, e con “shortnames” (i.e. nomi senza un dominio dopo di loro) it seems like Windows tries to resolve the name with something other than DNS.

I discovered that disabling NetBIOS manually (vedere come sotto) meant that network drives were connected correctly after a reboot. I realised that if I could disable NetBIOS via DHCP i could fix all the PC on my network with very little trouble. Ho provato questo (instructions below) and was again successful!

disabilitare manualmente

  • right click on the networking icon in the system tray
  • Open Network & Internet Settings
  • Change Adapter Options
  • Right click on the relevant connection and select properties
  • Double click onInternet Protocol version 4 (TCP / IPv4)”
  • Clicca su “Avanzato…”
  • Clicca sul “WINS” linguetta
  • deselezionare “Enable LMHOSTS Look-up
  • Select the radio box forDisable NetBIOS over TCP/IP
  • Reboot

Disattivazione tramite DHCP

  • This will depend on your DHCP systemmine is a pfsense router
  • Nell'opzione impostare le opzioni DHCP 43
  • Sulla mia casella di pfsense questo è impostato su una stringa con un valore di 01:04:00:00:00:02
  • On a sonicwall box I found the type was set tobytevalueand I had to use a slightly different format which was 0x01;0X04;0X00;0X00;0X00;0X02
  • In both instances we are effectively setting the same value which I believe is a hex. Si noti che entrambi hanno 6 “bit” with the values 1,4,0,0,0,2. For different systems I found a quick google will provide the appropriate format
  • Delete the previous IP lease on the DHCP system, and then do anipconfig /release” “ipconfig /renew” (2 separate commands) on the client
