When enabled, User Account Control (UAC) removes the privileges from the resulting token, denying access. This setting controls whether you can use a local account to connect to a remote server, for example, to a C$ share. Local accounts are a high risk, especially when configured with the same password on multiple servers. Recently we had this issue where scanning to a shared folder didn't work because the printer only supported SMBv1.Īpply UAC restrictions to local accounts on network logons: Enabled Note: In case you have an older device on your network, like a network printer, make sure it supports SMBv2 or higher before disabling SMBv1. The correct setting is Enabled: Disable driver. Be careful with the client driver setting-do not set it to Disabled because this will cause issues with the system. Therefore, Microsoft recommends completely disabling SMBv1 on your network.

SMBv1 is roughly a 30-year-old protocol and as such is much more vulnerable than SMBv2 and SMBv3. Configure SMB v1 client driver: Enabled: Disable driverīoth settings control the Server Message Block v1 (SMBv1) client and server behavior.
