“正在檢查網絡配置需求...檢查完成。此次檢查的總體結果爲: 未執行 <<<<
解決方案: Oracle 支持在具有 DHCP 分配的 IP 地址的系統上進行安裝。但在安裝之前, 必須將 Microsoft LoopBack Adapter 配置爲系統的主網絡適配器。有關在配置有 DHCP 的系統上安裝軟件的詳細信息, 請參閱 Installation Guide。”
解決方法：
在安裝ORACLE 10g前系統會檢測安裝的一些前提條件是否滿足，往往會提示說：將Microsoft LoopBack Adapter配置爲系統的主網絡適配器。
如果你沒有這樣配置，且你不希望安裝過程由於這個而出現問題，那麼可以按如下過程操作：
控制面板->添加硬件，在嚮導中選擇“是，已經連接了此硬件”→添加新硬件設備→安裝我手動列表選擇硬件(高級)→網絡適配器→廠商：Microsoft 網卡：Microsoft Loopback Adapter，添加完成，你會發現新建了個“本地連接”，用的就是這個假的“Microsoft Loopback Adapter”（因爲根本就沒有連接這個硬件，只是騙下Oracle而已）。把這個本地連接的IP設置一下（例如192.168.0.1）。好了，現在回去重新讓Oracle檢測一遍吧，應該通過了吧。

During Oracle installation on a windows machine that is configured to use DHCP in order to obtain its IP address, the Following message will probably be displayed:
Checking Network Configuration requirements …
Check complete. The overall result of this check is: Failed <<<<
Problem: The install has detected that the primary IP address of the system is DHCP-assigned.
Recommendation: Oracle supports installations on systems with DHCP-assigned IP addresses; However, before you can do this, you must configure the Microsoft LoopBack Adapter to be the primary network adapter on the system. See the Installation Guide for more details on installing the software on systems configured with DHCP.
As the error message say, this due to the fact that you are trying to install Oracle on a machine that is using DHCP to obtain its IP address. You can still install oracle on a machine without a constant IP address. All you need to do is configure the LoopBack adapter:
Install the Loopback adapter
1) Go to the control panel and choose add hardware
2) The Add Hardware wizard will be displayed, click Next
3) Choose “Yes, I have already connected the hardware” and click Next
4) An hardware list will be displayed. Navigate to the bottom of the list and choose “Add new hardware device”
5) Choose Install the hardware that I manually select from a list (Advance)”
6) Choose “Network adapter”
7) Choose “Microsoft” on the left side of the window and “Microsoft Loopback Adapter” on the right window”
8) Click Next and verify that Microsoft Loopback Adapter is about to install and click next again and finish.
Configure the loop back adapter
1) Go to control panel – network connections, you will see a new network connection.
2) Choose “local area connection 2” (the name may vary but basically it is the one we just added) and click properties.
3) Click on tcp/ip and then properties.
4) Enter an IP address and a subnet mask (you can use 1.1.1.2 and subnet 255.255.255.0)
Go to network connection and click on Advanced settings under the Advanced menu and verify that the loopback adapter is in the first one. (Update: it look like this step is optional because it seems to work in most cases anyway)
Now you can continue your oracle installation.
