my problem is our sales department and everybody of them connected to a switch for internet connection. today we can't connect for our email using ms outlook 2003/2007. when im using ipconfig it says 165.254.xxxx or the automatic private address. how can i go back to auto detect our DHCP enabled connection? As my troubleshooting, first i restarted the pc and unplug all the cables and plug again, restart the whole network, ping release and renew etc. is there anything i won't get that APIPA situation again when im connecting. thank you

Re: How to fix Automatic Private address
First: If you have a sales department, don't you have an IT department? And if not, WHY not?
You will get the APIPA address b/e your DHCP server is not working properly. That can be your router or your DHCP server. If that server is within reach go and check if DHCP is running. Otherwise restart that service.
It might help of you could describe your setup more detailed. What kind of server, how many PC's, problem with all of them (apart from sales)...

This solution is based on the assumption that this is your personal at home PC and not a member of any workgroup or on any connection that requires a proxy connection. These instructions are for Windows 7 and are very similar to Vista, if your OS is XP then I'm sorry I don't remember where these settings are but they have similar names so you should be able to find them.
1) Check your internet settings, ensure that it is configured to "automatically detect settings" >Control Panel>Internet Settings>Connections Tab>LAN Settings
Still not working?
2) Ensure that no alternate configuration has been input into your individual connection settings >Control Panel>Network and Internet>Network and Sharing Center>Change Adapter Settings>Right click on connection you want to use left click properties. Everything in this dialog box should be checked. Doubleclick Internet Protocol Version 4 (TCP/IPv4) The tickbox next to "Obtain an IP address automatically" and next to Obtain DNS server address automatically" should both be ticked. Go to Alternate Configuration Tab: Should be set to "Automatic Private IP Address"
3) >Control Panel>Network and Internet>Network and Sharing
Center>Change Adapter Settings>Right click on connection you want
to use and left click "diagnose"
If we haven't got it yet let me know and with a little more information we can try something else. In my experience this solves most connection related problems.
The internal ip address (differentiates the computers on your network) can be found by running the command prompt (start --> run--> cmd or start--> all programs --> accessories --> command prompt) and then typing int eh following command: "ipconfig" (without quotes). It will be the set of numbers in the form 192.168.something.something
Network Card's driver is not installed. Check and install drivers from Device Manager Window.
IP Address can be assigned automatically(through APIPA/DHCP) or Manually.
Automatic: There is no DHCP server, it takes the Automatic Private IP address(APIPA) or else get it from DHCP server by using "ipconfig" command Steps: Start>accessories>command prompt>ipconfig /renew
Manually: Right click on My Network Places> Properties>Right click on Local Area connection>Properties>General Tab>select Internet Protocol(TCP/IP)> Properties>General> select "Use the following IP address> assign IP, Subnet Mask, Gateway and DNS> Press OK Tab.
