Redirector Registry Settings
The following table shows the modifiable registry settings for the HKEY_LOCAL_MACHINE\Comm\Redir key.
Note The default registry values vary depending on which features are included in your platform. For more information, see Default Registry Settings.
| Value : type | Description |
|---|---|
| AllowedAuthMethods : REG_DWORD | A DWORD value that is treated as a bitmask.
Bit 0: LanMan authentication method enabled or disabled. Security Note When this authentication method is used, a password can be subjected to hacker attacks. Bit 1: Authentication that uses a security subsystem that is negotiated with the server. The protocol used depends on the settings of the security subsystem and the server capabilities. The negotiated authentication method can be NTLM, NTLMv2 and/or Kerberos. Security Note Disabling NTLM will cause authentication failure with down-level servers (such as Windows 95/98 or Windows NT) that do not support Kerberos. This will also cause failure for pass-through authentication, which is used by Windows CE Web server and DCOM components. |
| ClearTxtPwdAllowed : REG_DWORD | Default setting is zero (0). If this value is set to 0, the Redirector refuses connection to a server that negotiates cleartext passwords.
Specifies if a cleartext password is accepted. Security Note Setting this value to accept cleartext passwords allows anyone listening on the network to view passwords. |
| DefaultDomain : REG_SZ | Default setting is NULL. If this value is set to NULL, operations that require a default domain will fail.
Specifies a default domain for a NTLM security service provider to use for authentication. |
| DefaultDomainPDC : REG_SZ | Optionally specifies a primary domain controller for the default domain. |
| FindCacheMaxSize : REG_DWORD | Default setting is 8192. A value of zero (0) disables caching.
Specifies the maximum memory to use for find caching. |
| RecvBufSize : REG_DWORD | Default setting is 4096.
Specifies the size of the receiving buffer. |
| RegisterFSRoot : REG_DWORD | Default setting is 0, which does not expose the \NETWORK directory for mapped resources.
Enables a project to expose the \NETWORK directory. |
| ResourceExpiryInt : REG_DWORD | Default setting is 600.
Specifies the number of seconds before releasing unused resources. Note Because processing is performed on a periodic cleanup thread, it can take up to 60 seconds in addition to the specified time between the time that the file is closed to the time that the memory is released. |
| ServerTimoutMs : REG_DWORD | Default setting is 10000. You can double this value for slow interfaces, such as dial-up.
Specifies the number of milliseconds to wait for SMB responses. |
| SmbSignature : REG_DWORD | Default setting is 1.
A value of zero (0) means that SMB signatures are not used. A value of 1 means that SMB signatures are used if the server requires it. A value of 2 means that SMB signatures are used if the server supports it. Specifies SMB signing when communicating with the server. With Windows 2003 Server, SMB signing is required by default if the server is a domain controller. |
**Note **If settings change, the device must be warm booted before they take effect. Exercise caution when changing default values — this can affect system performance or the Redirector operation.
