pls help am using server 2003 i want to know how to install office 2007 or 2010 on it You can always create a VM on the 2003 Server to run as a Virtual Workstation within Server 2003 and install it to the virtual workstation that is running say a Virtual Workstation of Windows XP SP2 or newer OS within it.

Years ago I use to use Virtual PC 2007 to have a virtual XP Pro SP2 workstation that I could launch from a 2003 server. Here is more info:

Virtual PC 2007 Supported OS ( Server 2003 = YES ) http://support.microsoft.com/kb/831461

Here is link to Virtual PC 2007 download http://www.microsoft.com/en-us/download/details.aspx?id=4580

All you need is like an available license of XP to install to the Virtual PC 2007 to make a Virtual Hard Drive and then you can launch the Virtual XP ENVIRONMENT within Server 2003. Then while in that virtual environment you can insert the Office 2007 Disc and install directly to the virtual system.

You can then with the virtual system turned off, you can create a backup copy of the virtual system. For XP I think the clean virtual system of just XP Pro fully patched was around 4 or 5GB in SIZE.

*** NOTE: Virtual PC 2007 will request an allocation of physical RAM for the virtual machine. I have run XP on virtual machines on as little as 128MB, however for Office 2007 to meet the minimum system requirements you will want to allocate at least 256MB RAM. You will want to allocate more if you use other features etc... see this link for memory requirements and notation: https://wiki.csuchico.edu/confluence/display/help/Office+2007+-+Minimum+System+Requirements

The virtual machine will basically remove an allocation if memory from the servers physical memory as its own, so you dont want to take too much away from the real physical server, but find an amount that works and doesnt starve the server in memory from the other duties that this server has.

Lastly... you can run multiples of the Virtual PC 2007 virtual systems at the same time. Once I wanted to see how MANY virtual systems I could run at the same time, so I made duplicate copies of the virtual machine and then fired them all up. I was able to get 9 instances of XP all running at the same time on 192MB of RAM each on a Pentium 4 2.8Ghz HT with 2.5GB RAM which lagged it out badly with the CPU CORE(s) pegged at just about 100% to try to keep the juggle. I then deleted the 8 of the 9 virtual machines after since it would not have been legal to use 9 of the same license. It was just a test to see what would happen, but could not remain after the quick test due to legality reasons.
