Andrew, The following did not exist at the URL you provided. TransportBindName is there, but the SMBDeviceEnabled Registry value is not. Where did you find it? -- SMBDeviceEnabled Key: Netbt\Parameters Value Type: REG_DWORD—Boolean Valid Range: 0, 1 (false, true) Default: 1 (true) Description: Windows 2000 supports a new network transport known as the SMB Device, which is enabled by default. This parameter can be used to disable the SMB device for troubleshooting purposes. -----Original Message----- From: Andrew Oman [mailto:Andrew.Oman () predictive com] Sent: Friday, August 30, 2002 7:22 AM To: bugtraq () securityfocus com; vuln-dev () securityfocus com Subject: Re: SUMMARY: Disabling Port 445 (SMB) Entirely I hope this adds a little bit on one more method of diabling/unbinding SMB: ( sorry if the cross-post was not appropriate ) http://www.microsoft.com/ntserver/techresources/commnet/WINS/WINSwp98/WINS11-12.asp HKLM\System\Controlset001\Services\NetBT\Parameters Non-Configurable Parameters The following parameters are created and used internally by the NetBT components. They should never be modified using the Registry Editor. They are listed here for reference only. TransportBindName Key: Netbt\Parameters Value Type: REG_SZ - Character string Valid Range: N/A Default: \Device\ Description: This parameter is used internally during product development. The default value should not be changed. SMBDeviceEnabled Key: Netbt\Parameters Value Type: REG_DWORD—Boolean Valid Range: 0, 1 (false, true) Default: 1 (true) Description: Windows 2000 supports a new network transport known as the SMB Device, which is enabled by default. This parameter can be used to disable the SMB device for troubleshooting purposes. Using the SMBDeviceEnabled key removes SMB from binding to 445. Thanks, Andrew
