1
Dripping water
Dripping water (vertically falling drops) shall have no harmful effect on the specimen when mounted in an upright position onto a turntable and rotated at 1 RPM.
2
Dripping water when tilted at 15°
Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle of 15° from its normal position. A total of four positions are tested within two axes.
3
Spraying water
Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with a counterbalanced shield.
Test a) is conducted for 5 minutes, then repeated with the specimen rotated horizontally by 90° for the second 5-minute test. Test b) is conducted (with shield in place) for 5 minutes minimum.
4
Splashing of water
Water splashing against the enclosure from any direction shall have no harmful effect, utilizing either: a) an oscillating fixture, or b) A spray nozzle with no shield.
Test a) is conducted for 10 minutes. Test b) is conducted (without shield) for 5 minutes minimum.
5
Water jets
Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects.
6
Powerful water jets
Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects.
7
Immersion, up to 1 m depth
Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).
8
Immersion, 1 m or more depth
The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. The test depth and/or duration is expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion.
9
Powerful high temperature water jets
Protected against close-range high pressure, high temperature spray downs.
Smaller specimens rotate slowly on a turntable, from 4 specific angles. Larger specimens are mounted upright, no turntable required, and are tested freehand for at least 3 minutes at distance of 0.15–0.2 m.
There are specific requirements for the nozzle used for the testing.
The following is a list of common ports. During a network security audit, port scans will be performed to determine what network services are available. These services can be on different Operating systems.
The class sub-code provides a broad classification of the status. The enumerated values the class are defined as:
2.X.X Success
Success specifies that the DSN is reporting a positive delivery action. Detail sub-codes may provide notification of transformations required for delivery.
4.X.X Persistent Transient Failure
A persistent transient failure is one in which the message as sent is valid, but some temporary event prevents the successful sending of the message. Sending in the future may be successful.
5.X.X Permanent Failure
A permanent failure is one which is not likely to be resolved by resending the message in the current form. Some change to the message or the destination must be made for successful delivery.
X.0.X Other or Undefined Status
There is no additional subject information available.
X.1.X Addressing Status
The address status reports on the originator or destination address. It may include address syntax or validity. These errors can generally be corrected by the sender and retried.
X.2.X Mailbox Status
Mailbox status indicates that something having to do with the mailbox has cause this DSN. Mailbox issues are assumed to be under the general control of the recipient.
X.3.X Mail System Status
Mail system status indicates that something having to do with the destination system has caused this DSN. System issues are assumed to be under the general control of the destination system administrator.
X.4.X Network and Routing Status
The networking or routing codes report status about the delivery system itself. These system components include any necessary infrastructure such as directory and routing services. Network issues are assumed to be under the control of the destination or intermediate system administrator.
X.5.X Mail Delivery Protocol Status
The mail delivery protocol status codes report failures involving the message delivery protocol. These failures include the full range of problems resulting from implementation errors or an unreliable connection. Mail delivery protocol issues may be controlled by many parties including the originating system, destination system, or intermediate system administrators.
X.6.X Message Content or Media Status
The message content or media status codes report failures involving the content of the message. These codes report failures due to translation, transcoding, or otherwise unsupported message media. Message content or media issues are under the control of both the sender and the receiver, both of whom must support a common set of supported content-types.
X.7.X Security or Policy Status
The security or policy status codes report failures involving policies such as per-recipient or per-host filtering and cryptographic operations. Security and policy status issues are assumed to be under the control of either or both the sender and recipient. Both the sender and recipient must permit the exchange of messages and arrange the exchange of necessary keys and certificates for cryptographic operations.
X.0.0 Other undefined Status
Other undefined status is the only undefined error code. It should be used for all errors for which only the class of the error is known.
X.1.0 Other address status X.1.1 Bad destination mailbox address X.1.2 Bad destination system address X.1.3 Bad destination mailbox address syntax X.1.4 Destination mailbox address ambiguous X.1.5 Destination mailbox address valid X.1.6 Mailbox has moved X.1.7 Bad sender's mailbox address syntax X.1.8 Bad sender's system address
X.2.0 Other or undefined mailbox status X.2.1 Mailbox disabled, not accepting messages X.2.2 Mailbox full X.2.3 Message length exceeds administrative limit. X.2.4 Mailing list expansion problem
X.3.0 Other or undefined mail system status X.3.1 Mail system full X.3.2 System not accepting network messages X.3.3 System not capable of selected features X.3.4 Message too big for system
X.4.0 Other or undefined network or routing status X.4.1 No answer from host X.4.2 Bad connection X.4.3 Routing server failure X.4.4 Unable to route X.4.5 Network congestion X.4.6 Routing loop detected X.4.7 Delivery time expired
X.5.0 Other or undefined protocol status X.5.1 Invalid command X.5.2 Syntax error X.5.3 Too many recipients X.5.4 Invalid command arguments X.5.5 Wrong protocol version
X.6.0 Other or undefined media error X.6.1 Media not supported X.6.2 Conversion required and prohibited X.6.3 Conversion required but not supported X.6.4 Conversion with loss performed X.6.5 Conversion failed
X.7.0 Other or undefined security status X.7.1 Delivery not authorized, message refused X.7.2 Mailing list expansion prohibited X.7.3 Security conversion required but not possible X.7.4 Security features not supported X.7.5 Cryptographic failure X.7.6 Cryptographic algorithm not supported X.7.7 Message integrity failure

[:ask] According to default installation of Windows, the default keyboard layout (generally US - QWERTY) is used on login authenticaton screen. So how to change the default keyboard layout to my layout like french AZERTY or Swiss QWERTZ keyboard layout under Windows 2000 or XP.
[:idea] You need to change the keyboard layout of the default account to match the layout you do use.
Procedure:
This is correct to say that once you login to a system you can set what keyboard to use, but at logon time, the default selected keyboard is the same as the default keyboard layout that was chosen during the setup of Windows 2000/XP (in your case English–US).
For Windows 2000 there isn't any system settings you can change to add more keyboards for the logon dialog, but there is a workaround for those who have administrator rights to the computer. Here it is:
First add the keyboard layout you wanted to the your current user (open "Settings=>Control Panel=>Regional Options" and add a keyboard layout)
Open "regedit" in HKCU\Keyboard Layout\Preload
Look for the key you added
Create the same key value in HKU\.DEFAULT\Keyboard Layout\Preload
You will also need to replicate, the "Substitutes" folder.
Once you have set this up, you can select a different input locale in the logon dialog by:
1.Press the "Options >>" button. This will allow you to see the input locale in a blue rectangle. 2. Use <Right Alt>+<Shift> to toggle between the different installed input locales.
Now the good news is that Windows XP will make all this much simpler. The way you are able to do this is the following:
Open the "Regional and Language Options" in the Control Panel and go to the "Language" tag
Click the "Details" button and add all the keyboards you want to use in the logon window.
Go to the "Advanced Options" tag in the regional and language option.
Check the check box under "Default user account settings" (The system then applies all the settings of the current user account to the default user profile.)
Now when you go to the logon dialog do the same as mentioned above with the <Right Alt>+<Shift> key combination to toggle through the available keyboards.
