2. Server properties

(open a blank worksheet in a separate window)

The worksheet below contains the data of the Exemplum Primary School in order to demonstrate the purpose of the worksheet. Use the blank worksheet for your own server.

3. Password list

(open a blank worksheet in a separate window)

The worksheet below contains the data of the Exemplum Primary School in order to demonstrate the purpose of the worksheet. Use the blank worksheet for your own server.

NOTICE: For your convenience a reference to the place where a particular password is discussed in the SIG (ServerAtSchool Installation Guide) or the SUM (ServerAtSchool User Manual) is added in the Remarks-field in the worksheet below.

(...10 more blank password forms snipped to save some space...)

Additional passwords can be added to the extra password forms in the blank worksheet, such as:

• the username/password for the router of your xDSL/cable connection
• the username/password for managing your network switches
• the username/password for remote networkprinter administration
• the usernames/passwords/license codes for all educational software packages
• etc. etc.

4. Calculating the NoDrives registry setting

(open a blank worksheet in a separate window)

You can remove the icons representing selected drives from My Computer and from Windows Explorer by setting the key NoDrives in [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] in the Registry. NoDrives is a bitmapped value where individual bits each represent a single drive letter. Here are some commonly used values:
03FFFFFF - suppress all drive letters
03FFFB7F - suppress all drive letters except K: and H:
03FFFB76 - suppress all drive letters except K:, H:, D: and A:
03DFFB72 - suppress all drive letters except V:, K:, H:, D:, C: and A:
00000000 - suppress no drive letters at all.

The worksheet can be used to convert the desired bit pattern to the corresponding hexadecimal value that needs to be entered into the Registry.

The table operates as follows.

1. In the row 'Binary', set a 0 for every drive you want to be visible in 'My Computer' and a 1 for every drive you want to hide.
2. In the row 'Binary' you now have a row of 32 zeros and ones (32 bits). The 26 bits at the right hand side correspond to the drive letters Z: to A:, the remaining 6 bits at the left hand side are unused and already set to 0.
3. Convert the 8 groups of 4 bits to the corresponding hexadecimal digit using the 'Binary to hexadecimal' translation table below and write down the answers in the row 'Hexadecimal'.
4. The row 'Hexadecimal' now shows the value that needs to be entered into the registry.

Here is an example which suppresses all drive letters except V:, K:, H:, D:, C: and A:.

5. Calculating the NoDriveTypeAutorun registry setting

(open a blank worksheet in a separate window)

Various drive types can be configured to automatically start 'playing' whenever a new media carrier (diskette, CD-ROM) is inserted into the drive. This feature can be enabled by setting the corresponding bit in the bitmapped value NoDriveTypeAutorun in [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] to 0 and can be disabled by setting the corresponding bit to 1.

The table below works as follows.

1. For each of the rows enter the desired value (0 or 1) in the corresponding column. The column 'bit 0' corresponds to 'Disables autoplay on drives of unknown type (0)', 'bit 1' corresponds to '(reserved)', etc.
2. Copy each of the 8 bits entered to the row labeled 'Result (binary)'.
3. Convert the 2 groups of 4 bits to the corresponding hexadecimal digit using the 'Binary to hexadecimal' translation table below and write down the answers in the row Result ('hexadecimal)'.
4. The row 'Result (hexadecimal') now shows the value that needs to be entered into the registry.

By default, Autoplay is disabled on network drives and on removable drives, such as the floppy disk drive (but not the CD-ROM drive). The default hexadecimal value is 95. If the Autoplay function is to be disabled for CD-ROM-players too, then 'bit 5' must be set to 1. This yields a hexadecimal result of B5, as illustrated below.

6. Collecting MAC-addresses and other information

(open a full blank worksheet in a separate window)

NOTICE: The full worksheet that opens in the separate window is quite large; printing it will produce more than a few pages of output. The tables below show only part of the full worksheet to save some space in this example.
