We face the problem, not able to connect to LAN or WLAN where the network status shows media disconnected. But, the media is connected and able to see the LED bliniking at the adapter.

Checked the LAN network devices found lot of devices with Miniport created for each adapter with suffix as Mcafee NDIS Intermediate Filter Miniport / Deterministic Network Enhancer Miniport & Packet Scheduler Miniport, which are all showing yellow exclamatory mark on each entry.

Please help.

This seems to be part of the McAfee Host Intrusion Prevention. I'd suggest uninstalling McAfee NDIS Intermediate Miniport adapter to determine if the adaptor is the root cause.

To uninstall the adapter:
Click Start, Run, type cmd, then press ENTER.
To stop the McAfee Host Intrusion Prevention service, type the command below and press ENTER:
NET STOP enterceptagent
To unload the McAfee firewall drivers, type the command below and press ENTER:
NET STOP firepm
Open the Host Intrusion Prevention agent installation directory, type the command below, and press ENTER:
Cd Program Files\McAfee\Host Intrusion Prevention\inf\
Uninstall the NDIS adapter, type the command below, and press ENTER:
installfirehk /u
Start the McAfee Host Intrusion Prevention service, type the command below, and press ENTER:
NET START enterceptagent
Reproduce the issue to verify if the NDIS adapter is causing the issue.

I hope this helps

its a Ghosted Netwrok Adaptor.

To uninstall the ghosted network adapter from the registry using one of the following methods:

1.      Click Start, click Run, type cmd.exe, and then press ENTER.
2.      Type set devmgr_show_nonpresent_devices=1, and then press ENTER.
3.      Type Start DEVMGMT.MSC, and then press ENTER.
4.      Click View, and then click Show Hidden Devices.
5.      Expand the Network Adapters tree.
6.      Right-click the dimmed network adapter, and then click Uninstall.

Helpothers: Thanks for your comments. We found the NDIS driver installed with Windows XP SP-3 machine needed driver updation.
