Thank you for reporting this issue. It seems we introduced a bug when modifying the SMB-related code to support Kerberos authentication. Previously, shared folders were accessed using an IP address with NTLM authentication, prepending \\ to the IP (e.g., \\x.x.x.x).
However, a customer recently reported that the Network Scanner didn't support Kerberos and failed when NTLM was disabled. This was because Kerberos requires network shares to be accessed via a fully qualified domain name (FQDN) rather than an IP address. To address this, we updated the code to use the FQDN where available, but we inadvertently omitted the required \\ prefix before the FQDN, unlike with IP addresses. This caused the bug you encountered.
The issue should now be resolved in
this build by ensuring the \\ is correctly prepended to the FQDN. Please give it a try and let us know if it works as expected.
