Customer is running av Win 2003 server as domain controller in a small LAN (less than 10 users). Recently they installed a multi-function printer and attached it to the LAN. This unit is configured to scan to a specified folder on the server.
In order for this to work, the printer supplier defined two registry settings on the server:
HKLM/System/CurrentControlSet/Services/lanmanserver/requiresecuritysignature value = 0
HKLM/System/CurrentControlSet/Services/lanmanserver/enablesecurityseignature value = 0
These settings seems to work for a short time, but then they are reset or changed to a value of 1 (which causes the scanner to stop working).
I'm not sure what these settings are doing, but suspect that they're used to get access to the server (without defining a specific user/password). Questions are then: What is causing these settings to change?. Any ideas how to make this work better?
