I recently installed a SonicWall TZ270 Firewall in my home office environment. I have four different "zones" set up. The work zone has my main work PC, a Windows 2012 file server, a NAS device, and a network printer in it. I am having several problems with mapped networked drives that just started after installing the SonicWall and may be due to its configurations and policies.
First, I have three mapped drives on my Windows 2012 Server: G-drive, L-drive, and O-drive. When I boot up my work PC and open explorer all three drives have a red X through them and the following error message:
An error occurred while reconnecting G to \\myserver\G-drive
Microsoft Windows Network: The local device name is already in use. The connection has not been restored.
I tried disconnecting the drive and remapping to no avail. I am having issues accessing my Sonic Firewall (see other question), but am pretty sure I did not set up any policies allowing or blocking any Work zone to Work zone services.
I am also having problems mapping my NAS drives. I have four different drives on my NAS mapped on my work PC. I recently upgraded my work desktop from Windows 7 to Windows 10. After the upgrade, I needed to manually map each drive when I booted my work desktop. I posted a question about this in June and followed advice from arnold and solved this with a bat file that runs on startup and got around this by writing a I have a small bat file on startup that contains:
net use [drive[: /delete
net use [drive]: \nas\sharename /persistent:no
Everything worked fine until the TZ270 firewall was installed. Now when the cmd window opens it asks me to enter my username and password for each of the four network drives every time after boot up.
1. Is all of this because the 270 is blocking some service(s) between different computers on the same Work Network?
2. If yes, which services should I create a policy for to allow Work to Work communication?
3. If not, how do I solve these problems?
