IPAC_OFF.INF - DISABLE TCP/IP IP AUTOCONFIGURATION

The Windows ME TCP/IP stack supports a new mechanism for automatic address assignment of IP addresses for simple LAN-based network configurations. IP Autoconfiguration Addressing is an extension of dynamic IP address assignment for LAN adapters. It enables configuration of IP addresses without using static IP address assignment or installing a Dynamic Host Configuration Protocol (DHCP) server.

If a network LAN adapter is configured for TCP/IP, and if "Obtain an IP address automatically" is selected on the IP Address tab in the TCP/IP Properties dialog box, Windows ME TCP/IP attempts to find and use a DHCP service on the attached network to obtain a dynamically assigned IP address. If it does not find a DHCP service, Windows ME uses IP Autoconfiguration Addressing by assigning the adapter a Class B IP address out of the network number 169.254.x.x IP address space. In this way, two PCs can be plugged into a LAN hub and can start without any IP address configuration, and can use TCP/IP networking for internetworking. Each computer that uses IP Autoconfiguration Addressing gets an IP address and tests to determine that the IP address is unique and not already in use on the LAN.

IP Autoconfiguration Addressing is enabled by default. IP Autoconfiguration Addressing can be controlled by setting the value of IPAutoconfigurationEnabled (type DWORD) in the registry key

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\DHCP

If the value of IPAutoconfigurationEnabled is nonzero or if the registry key is absent, IP Autoconfiguration Addressing is enabled. An IPAutoconfigurationEnabled value of 0 disables the IP Autoconfiguration Addressing feature.

If Windows ME initially does not detect a DHCP service and configures an IP Autoconfiguration IP address, and then subsequently discovers a DHCP service on the network, Windows ME uses the DHCP service and switches from 169.254.x.x addressing to IP addresses assigned by a DHCP server.

To set the registry value for IPAutoconfigurationEnabled value to 0:

  1. Select IPAC_OFF.INF in the \Tools\PSSutil folder on the Windows Millennium CD.
  2. Right-click IPAC_OFF.INF
-or-

Hold down the SHIFT key and press F10.

  1. Choose INSTALL to modify the IPAutoconfigurationEnabled value.

IPAC_ON.INF - ENABLE TCP/IP IP AUTOCONFIGURATION

Refer to the previous section for information concerning IP Autoconfiguration.

IP Autoconfiguration Addressing is enabled if the value of IPAutoconfigurationEnabled is nonzero or if the registry key is absent.

To set the registry value for IPAutoconfigurationEnabled value to 1:

  1. Select IPAC_ON.INF in the \Tools\PSSutil folder on the Windows Millennium CD.
  2. Right-click IPAC_ON.INF
-or-

Hold down the SHIFT key and press F10.

  1. Choose INSTALL to modify the IPAutoconfigurationEnabled value.

NNT.INF - REMOVE THE NAMENUMERICTAIL VALUE FROM THE REGISTRY

If you add the "NameNumericTail=0" value to the registry (as documented on page 688 of the Microsoft Windows 95 Resource Kit) and then run Windows ME Setup, Microsoft Plus! ME Setup, or the Add/Remove Programs tool in Control Panel, programs in the Program Files folder may no longer work correctly.

When you add the "NameNumericTail=0" value to the registry, Windows ME Setup, Microsoft Plus! Setup, or the Add/Remove Programs tool may change the short name for the Program Files folder. For example, if you run the Add/Remove Programs tool after you add the "NameNumericTail=0" value to the registry, the short name for the Program Files folder may be changed from Progra~1 to Programf.

If the short name for the Program Files folder is different from the name that the program you are trying to run expects, the program may not be able to locate the folders and files it needs.

Various tools and components installed in the Program Files folder may use short file names internally or during installation. If the short name for the Program Files folder is different from the short name expected by a tool or component, the problems described in this article may occur. This problem can affect any program installed in the Program Files folder.

The "NameNumericTail=0" value is not supported in Windows ME. Although this registry value works as expected, it can cause problems for Windows ME components.

To correct this problem, follow these steps:
  1. Delete the value "NameNumericTail=0" from the following registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem
  2. Using Windows Explorer or My Computer, rename the Program Files folder to Programs.fld.
  3. Rename the Programs.fld folder to Program Files. Note: Renaming the folder forces a new short name for the folder to be generated.
To remove the NameNumericTail value from the registry:

  1. Select NNT.INF in the \Tools\PSSutil folder on the Windows Millennium CD.
  2. Right-click NNT.INF
-or-

Hold down the SHIFT key and press F10.

  1. Choose INSTALL to remove the NameNumericTail value.

PTXT_ON.INF - SENDS PLAIN-TEXT PASSWORDS TO YOUR NETWORK SERVER

For security reasons, Windows ME will not allow you to send plain- text passwords. The password is encrypted by default. However, Samba servers require plain-text passwords, so you will not be able to connect to Samba servers unless you change a Registry entry to enable plain-text passwords. 

   Caution: Enabling plain-text passwords could compromise security.


To enable plain-text passwords, add the Registry entry for EnablePlainTextPassword (as a Dword) and set the value to 1 in the following Registry location:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\VNETSUP

To set the value for EnablePlainTextPassword to 1:

  1. Select PTXT_ON.INF in the \Tools\PSSutil folder on the Windows Millennium CD.
  2. Right-click PTXT_ON.INF
-or-

Hold down the SHIFT key and press F10.

  1. Choose INSTALL to add the EnablePlainTextPassword entry and set its value to 1.

PTXT_OFF.INF - SENDS ENCRYPTED PASSWORDS TO YOUR NETWORK SERVER

To re-enable the sending of encrypted passwords to your network server, add the Registry entry EnablePlainTextPassword (as a Dword) and set the value to 0 in the following Registry location:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\VNETSUP

To set the value for EnablePlainTextPassword to 0:

  1. Select PTXT_OFF.INF in the \Tools\PSSutil folder on the Windows Millennium CD.
  2. Right-click PTXT_OFF.INF
-or-

Hold down the SHIFT key and press F10.

  1. Choose INSTALL to add the EnablePlainTextPassword entry and set its value to 0.

REMFDMA.INF - DISABLES FDMA ON PCI-ISA BRIDGE DEVICES

Having FDMA capability enabled on some PCI-ISA bridge devices can result in loss of audio when recording using an Aztech 2320 based audio device and the Aztech 2320 WDM audio driver. REMFDMA.INF will disable FDMA capability on the PCI-ISA bridge, allowing audio recording to function properly. However, with FDMA disabled, digital joysticks may not operate properly.

To disable FDMA:

  1. Select REMFDMA.INF in the \Tools\PSSutil folder on the Windows Millennium CD.
  2. Right-click REMFDMA.INF
-or-

Hold down the SHIFT key and press F10.

  1. Choose INSTALL to disable FDMA capability.
  2. Restart your computer.

ADDFDMA.INF - ENABLES FDMA ON (SOME) PCI-ISA BRIDGE DEVICES

Having FDMA capability disabled on some PCI-ISA bridge devices can result in the degradation, or loss, of digital joysticks' operability when audio is playing. ADDFDMA.INF restores FDMA capabilities that were disabled with REMFDMA.INF. 

   Note: Not all PCI-ISA bridge devices are able to take advantage of

FDMA, regardless of whether or not ADDFDMA.INF or REMFDMA.INF are used. Also, enabling FDMA on some PCI-ISA bridge devices may result in loss of audio during record operations when using an Aztech 2320 based audio device and its WDM audio driver.



To enable FDMA:

  1. Select ADDFDMA.INF in the \Tools\PSSutil folder on the Windows Millennium CD.
  2. Right-click ADDFDMA.INF
-or-

Hold down the SHIFT key and press F10.

  1. Choose INSTALL to enable FDMA capability.
  2. Restart your computer.
