Windows 2008 server vs Windows 2003 server


I started to apply the Windows 2008 server.

I saw one improvement (compared with Windows 2003 server), such as:

1)      Function of Server Manager
•      All the files have been there (after the installation); we do not need to “insert the CD” for the installation of DNS, etc
•      No need to install the GPMC

I do not see “other improvements”

My question: Somebody saw other improvements of Windows 2008 server (compared with Windows 2003 server), If yes, would you mention or say it (which ones?) please

Thank you

Once you install Windows 2008 R2, there should be no reason to insert the CD to install DNS. The compaonents for DNS are copied into the boot partition during the installation of the O/S. All you do is go into Servwer manager and install the Role and it activates that portion of the functionality and you enter the DNS specifics you want.

GPMC is not necessarily required if you don't need it, but it's good to have just incase.

Oh, yes, 2008 is much more secure than 2003 and it has some new features built in. A few are Partition shrink/enlarge, better support for the newer devices, Capacity for more ram, IIS 7.5, Windows backup is better than the old NT Backup, Redesigned HyperV and many more enhancements.
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Windows 2008 is 5 years more mature.  Is like comparing a 7 year old with a 12 year old.  I would recommend that you evaluate exactly what you need.

But to answer your question, if you have to deploy a new server or do an upgrade on a server, I say do it unless the application that your company runs on do not run on Windows 2008.  

so many optimizations and improvements added.

I agree to all above.
Please install windows 2008 and just start using it then you will feel the difference.
MS will release new version by adding the new user requirements which they get from the previous OS and the new features they found by continuous R&D.

So please dont think backward. This is for your good.
please install the new version and try with a dummy apps or as a member server

There is a lot more in Server 2008 and a lot of improvements under the skin

I think you should go a step further and leave out 2008 server, but rather go for 2008 r2 server. 2008 server is based on the Vista kernel, which isn't that good and is getting obsolete too, while 2008 r2 is based on the Windows 7 kernel, which is still current and very good. Apart from that all 2008 r2 server versions are 64 bit, which means that all of them support above 4GB of RAM directly. With 2008 server you can also get 32bit versions, and those will only have limited access to the RAM above 4GB.

Apart from that 2008 r2 server already includes the advantages mentioned above. I also don't know how much longer 2008 server will be supported by m$, but probably that won't be much longer than Vista.

RAM limit of windows2008 32bit is 12GB
rindiConnect With a Mentor Commented:
It depends on whether you are using the web, standard, enterprise or datastore versions, and then you need the pae switch which doesn't give you the full functionality that a 64bit OS gives you for your RAM.

> RAM limit of windows2008 32bit is 12GB

This is incorrect.  The RAM limit is still 4 GB.

If you believe it to be correct, please cite your source.

As for other improvements, there are MANY.  As to improvements you can "see" that depends on what you do with the server.

If your primary responsibility is administering multiple servers in small & medium companies like we are, then Server 2008 R2 is the first choice. Yes, Microsoft products are not always the easiest or bug free, but they outperform other servers in that workspace and provide the functionality we need to allow our clients to conduct business properly and keep us employed today and tomorrow if we can keep up with the new technology and demands our users have.

Here is a document that should provide all the info on R2 that you might need.

Just want to share with our experts regarding ram limitations

@ leew
Please correct me if I am wrong as I got confused by your comment and the MS article

What is confusing?

The one thing I'll clarify - 32 bit Standard is limited to 4 GB (as the link states).  Enterprise/Datacenter is limited to 64 GB but even with that, it's not REALLY 64 GB - there are certain limitations to stacks and other memory related items that make 64 GB on 32 bit NOT equal to 64 GB on 64 bit in terms of overall RAM capabilities.

Many thanks to leew.
My server running with 12Gb without any issues. But as you said there will be limitations that I might have not noticed.

Thanks once again
