Trouble with Teaming | See notes and warnings in the Teaming page. |
The computer has trouble detecting both ports on a dual port adapter |
Adding the Intel PRO/100 S Dual Port Server Adapter through hot plug may present some difficulties.
If your second port is not detected, a restart may be required. When installing this adapter in NetWare with hot plug, include the |
Windows 98 is unable to update device driver files |
If you're using Windows 98 and have updated or added an adapter, you may experience a problem with device driver update files not being
copied. (This is a known problem, for which Microsoft has published a Knowledge Base article, Q242150.)
To resolve this problem:
|
Install prompting for Prodd.vxd and Prokddp.vxd files in Windows 2000 or 98 |
If you use the Add/Remove Programs icon in the Windows Control Panel to remove an Intel adapter, and then try to install drivers from a later
Intel CD, you may see a prompt asking for the following files: "Prodd.vxd" "Prokddp.vxd" This is because Windows is attempting to install the files associated with the earlier driver, which are not present on the later Intel CD. To resolve this problem, finish the installation and choose "Skip" when prompted for a missing file. Then, instead of removing the driver, update it with the later Intel CD. For instructions on updating the adapter driver, see the "Install the Network Drivers" section in the online guide on the Intel CD. |
After upgrading operating systems, Intel PROSet is no longer available | If you are upgrading Windows operating systems and you have Intel PROSet II software installed, it will be deleted in the process. You will need to reinstall Intel PROSet II. |
In Windows XP, IP addresses are lost or Intel PROSet becomes unstable with bridging enabled |
With bridging enabled, Intel PROSet II does not retain adapter IP address information. If changes are made to any Intel PROSet II advanced feature after enabling bridging, the Intel PROSet II software becomes unstable. |
Terminal Server support | When using Terminal Server, make sure only one session of Intel PROSet II is open at any one time. Simultaneous sessions are not supported in Intel PROSet II. |

Use the drivers that came with your adapter, or download the latest ones from the Intel support web site.
If the LINK light is not on, check all connections at the adapter and link partner. Make sure the link partner matches the link partner or is set to auto-negotiate, and the driver is loaded. (The link indicator will not be active until the driver is loaded.)
Make sure the cable is installed properly. The network cable must be securely attached at all connections. If the cable is attached but the problem persists, try a different cable.
For 100 Mbps, make sure the cable is a 4-pair Category-5 or better.
Test the adapter. Run the adapter and network tests described in Test the Adapter.
Check the Common problems table and try the recommended solutions
If none of these works, check the Late-breaking News document that came with the adapter or check the Intel support Web site. See Intel Customer Support for information on connecting to Intel's online services.
When configuring a multi-adapter environment, you must upgrade all Intel adapters in the computer to the latest software.
If the computer has trouble detecting all adapters, consider the following:
Your operating system may need to re-enumerate the bus, especially if any devices with bridge chips are used. To force the re-numeration, uninstall or unload the drivers for all PCI devices installed and shutdown the computer. Then restart the computer and reinstall or reload all drivers.
The Intel PRO/100 Dual-Port adapter incorporates a PCI bridge device which allows the card to appear as two adapters to the PCI bus controller. When configuring a multi-adapter environment - when one of the adapters is a dual-port device (such as the Intel PRO/100 S Dual Port) - you must upgrade all Intel adapters in the computer to the latest software.
The "Plug and Play OS" setting in the BIOS should be set to "No" for Windows NT 4.0 and most other non-Windows operating systems.
Check the sections on installing driver software for your particular operating system for further information.
If the adapter is not recognized by your OS or if it does not work you may need to change some BIOS Setup program settings. Try the following only if you are having problems with the adapter.
You may need to change the Plug and Play setting in your computer's BIOS. See your computer's manual for instructions on how to access.
Enable the PCI slot. In some PCI computers, you may need to use the BIOS Setup program to enable the PCI slot.
You must install the network adapter in a bus master slot. Some BIOS Setup programs require you to enable the slot for bus master/master. Check your BIOS Setup program and the computer's documentation to make sure the slot is set for bus master/master.
Configure the slot for level-triggered interrupts. The PCI slot the adapter is using must be configured for level-triggered interrupts instead of edge-triggered interrupts. Check your BIOS Setup program to make sure triggering is set up.
Reserve interrupts and/or memory addresses into the BIOS. This prevents PCI cards from trying to use the same settings as ISA cards. Check your BIOS Setup program; there may be IRQ options such as Enable for ISA or Disable for PCI.
Here are some examples of BIOS Setup program parameters:
PCI slot #: Slot where the adapter is installed (1-3)
Master: ENABLED
Slave: ENABLED
Latency timer: 40 - 80
Interrupt: Choose any one of several that the BIOS Setup provides.
Edge-level: Level
The exact wording of the parameters varies with different computers.
If you insert a 64-bit PCI card into a 32-bit PCI slot, it will operate correctly, but not at peak performance.
If you insert a 32-bit PCI card into a 64-bit slot, it will also operate correctly, but there will be no performance gain, and the bus will be slowed.
The same conditions apply with PCI-X cards in a PCI slot, and vice versa. For example, if you have a 133mhz PCI-X adapter card and insert it into a PCI slot, it will still work, but far below its rated capacity.
The entire bus will operate at the speed of the slowest PCI card installed in the bus.
Attaining gigabit speeds requires that many components are operating at peak efficiency. Among them are the following:
Cable quality and length. Do not exceed the maximum recommended length for your cable type. Shorter lengths provide better results. Straighten kinks and check for damaged sections of cable.
Bus speed and traffic
Processor speed and load
Available memory
Transmission frame size
Operating System - Features vary by OS compatibility, such as offloading and multiprocessor threading.

NOTE: On NT4.0 computers, some applications may cause incorrect behavior and even blue screen at deserialized drivers. This is an operating system bug admitted by Microsoft that currently won't be fixed in NT4.0. This bug was fixed for Windows 2000 and later. Intel's base drivers are not affected. |
This section lists the current known issues that have been observed by our testing labs.
Issue: network adapter in systems that use the Intel 450GX chipset.
Symptom: The computer locks up after running for a few minutes.
Description: The 450GX chipset has an errata related to "zero-byte" write cycles that causes a system failure under certain conditions. For more information on the errata, download the latest specification update for the Intel® 450KX/GX chipset. A link to this specification update can be found at:
http://support.intel.com/support/chipsets/450GX/Solution: Run BIOS setup and change IOQ Depth From Auto or 8 to 1.
The server hangs when the drivers are loaded.
Change the BIOS interrupt settings. See PCI Installation Tips for more information.
If you are using EMM386, it must be version 4.49 or newer (this version ships with MS-DOS 6.22 or newer).
Diagnostics pass, but the connection fails or errors occur.
At 100 Mbps, use Category 5 wiring and make sure the network cable is securely attached.
At 100 Mbps, connect to a 100BASE-TX hub/switch (not 100BASE-T4).
For NetWare, make sure you specify the correct frame type in your NET.CFG file.
Make sure the duplex mode setting on the adapter matches the setting on the switch.
The Wake on LAN feature is not working. (NOTE: Only the PCI 2.1 bus requires a WOL cable. The PCI 2.2 bus does not have a cable.)
Make sure the WOL cable is attached and that power is being applied to the computer.
Check the BIOS for its WOL setting. Some computers may need to be configured for WOL using the BROW utility in the \BootAgnt directory on the CD. On server adapters, the WOL setting is Off by default.
Make sure the network cable is fully attached to the adapter.
The IPv6 protocol does not seem to work after updating adapter drivers on Windows 2000 Advanced Servers.
When using a Windows 2000 Advanced Server SP1 with IPv6 bound to the adapter,
you must unbind the IPv6 protocol from the adapter before updating drivers. This is a result of the operating system implementation of the IPv6 protocol. To update an adapter using the IPv6 protocol:
- Unbind the IPv6 protocol from the adapter. To find the IPv6 setting, click
Start > Settings > Control Panel > Network and Dial-Up connections >
Local Area Connection ###. Right-click the Connection number to open
the Adapter Properties dialog box. Clear the IPv6 checkbox then click OK.- Update drivers.
- Bind the IPv6 protocol to the adapter. In the Adapter Properties dialog box,
click the IPv6 checkbox. See step one for detailed instructions on finding
the IPv6 option.
