Using Windows DHCP Server or Cisco DHCP Server

We have a Windows 2003 network. We also have a Cisco ASA Device which is currently assigning DHCP addresses. Would are the benefits of using the DHCP server on one of our 2003 domain controllers instead of the DHCP on the Cisco ASA. Please provide as much detail as possible. Thank you,

I do not know how configurable the cisco device is but on windows you can do a lot of things.

You can reserve IPs, set up default gates, DNS, WINS and other service/server addresses that clients may need to have.

Set up lease times and renew timer.

If your using DNS on the windows server you can get it update as DHCP sends addresses out.

Also has a GUI.

yes you have many more options in windows DHCP server than hardware device

Oh also you can install the DHCP service if you like on the windows server but just leave it unauthorized and it will not give out any IPs. This way you can configure it and see if you like it better. If you do then you can authorize it and then it will start giving out IPs. You can unauthorize it agn if you like as well.

Well, I guess I understood that it had more functions than a Cisco Router to offer, but what are the benefits of using the on Windows compared to on a Cisco device. Example, does it make the management of  AD, DNS, or easier. I already know what dhcp is and how to confgiure on the server. please see the first question. .....

You can get the DHCP to update your DNS

IF IT IS WINDOWS EVEN YOU CAN HAVE SECONDARY DHCP SERVER WITH SAME DATABASE AS FAIL OVER .

Ok grate, no we got it..
Ok, "YES ACTIVE DIRECTORY INTEGRATION ,DNS INTEGRATION ALSO ADAVANTAGES "
Could you enlighten me on the AD and DNS inergration and give some detail on how it works to advantage. Some coworker keeps saying the above, but he is not sure why?? For example, what does the DNS integration do??????

Lastly, why would anyone then do it outside of windows with all these benefits?. (may be they don't know enough like us :-)  ))))

The AD integration of DHCP and DNS just removes alot of work that you may or may not be doing with your DNS server.
All DNS updates are automatic so you'll only need to setup static DNS records for those machines that aren't getting IP's via DHCP anything else is updated in DNS when it is leased a new IP. I'm not sure what your current setup is like but this can remove alot of admin overhead.

Central management is greatly simplified aswell, if you have multiple sites with AD servers at each site you can manage DHCP from one spot instead of having to connect to each switch/router etc.

I can't think of a great deal of other advantages but then again i've never used anything else, it's basically just setup and forget. I've never had issues with it and if i need to add a new static IP or make a change somewhere it's literally a 1 minute brainless job rather than commandline pain.

I can't really think why anyone in an AD environment would use something other than Windows DHCP... they just go together.

In an AD environment, AD, DNS, DHCP, certificate, computer ip addresses are usually integrated.  If you've AD, then you should do it this way.  First is it is easy to monitor and administer because it's GUI.  AD should have its own DNS and DHCP will do the job on updating the DNS if there are any clients who wish to be added to the server.  Unlike if you use ASA, this is not possible because it has its own database.

About your question some people use the ASA or some other DHCP server, usually they do this if the company is not that big, no domain environment and they don't have inhouse servers to host the DHCP service.  Different companies have different needs, not just because they don't know it ;)  Peace bruv.
