DHCP server denied.
 

Can't access internet due to below DHCP error,

The IP address lease 100.64.227.64 for the Network Card with network address 001E101FBCAD has been denied by the DHCP server 100.68.69.210 (The DHCP Server sent a DHCPNACK message)

OK, so does this have anythign at all to do with linux?? You've not provided any mention of any software involved, let alone the logs of the relevant services. Is that address even meant to be valid?

I am using windows xp as guest os & rhel 5.4 as host os. In Network Connections there are three LAN card are available.

1. Local Area Connection (default with windows xp installation)
2. Local Area Connection 16(installation HUAWEI Mobile Connect 3G data card)
3. Local Area Connection 7(create for rhel 5.5 virtual os)

Internet get disconnect when i enabled "Local Area Connection 7"
& get below error.

The IP address lease 100.64.227.64 for the Network Card with network address 001E101FBCAD has been denied by the DHCP server 100.68.69.210 (The DHCP Server sent a DHCPNACK message).

why are you looking to request a public IP from a DHCP server? What DHCP server are we even using? This looks to be between your ISP and windows? Nothing to do with Linux still?

Exactly i don't have any problem in rhel but when i enabled other LAN card (Virtual LAN Card)for rhel then internet get disconnect.
