Permanently map network drive in Windows

May 2, 2012

Have you ever run into an issue when after mapping a network drive and saving login/password you end up with disconnected drive after a reboot? To overcome this problem use command line with the following switches to net use routine:

net use w: \\server\share /savecred /persistent:yes

Then enter your username and password and that seems to be it.

But I had a problem when network drive doesn’t map with error: “Invalid username/password”. Even though they are correct. If you run into a similar problem include username and password into the command like this:

net use w: \\server\share password /savecred /persistent:yes /user:username

Old share mapping upon reboot

February 25, 2012

When you change share mapping in users AD logon scripts, for example if you move share to another server, after a reboot users can still see an old path in their drive mappings. Usually it happens if you forget to unmount drive before mounting. If share was already mounted before it won’t remount to a new one. To get rid of that, always add something like net use N: /d /y before mounting line.

However, sometimes it screws up. In case you steel see an old share go to HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\ CurrentVersion\ Explorer\ MountPoints2 and remove cached record for this share. It will look something like ##SERVERNAME#SHARENAME. After that you will hopefully have your share automatically mounted to the correct path.

I made several pictures of tape library which serves as primary backup facility in our data centre. Here what you can achieve with this library in maximum configuration:

  • 18 drives with more than 9TB/hour throughput.
  • Up to 575 cartridges and 862TB of uncompressed storage.

Our configuration is rather small, 2 drives and 45TB of storage.

Here you can see how robo-arm performs library inventorization by reading barcodes with infrared scanner:


Both tape drives and robot are connected to NetApp filer with SCSI cables. All data is backed up from disk shelves directly to tape library via NDMP protocol. There is no need to feed data through backup server which eliminates any LAN congestion.




Here are connections to NetApp:
