Error "adprep.exe is not a valid win32 application"...

[Guest SammyBar]

Hi all,

 

I'm upgrading a Windows Server 2000 DC based network to Windows Server 2003

R2 64 bits. One of the first steps is to prepare the existing Active

Directory to contain W2K3 DCs. It is done by adprep /forestprep. I

downloaded the ISO images for W2K3 64 bits installation CDs. The first

problem is the adprep.exe utility does not is available at \i386 folder of

the CD as the documentation says. I found it only at \AMD64 folder. But when

running it I get the error "adprep.exe is not a valid win32 application". I

suppouse the W2K3 64 bit installation media only comes with the 64 bit

version of the adprep utility. It sounds consistent but this utility is

supposed to prepare a W2K server which is only available in 32 bits!

Any way, what to do? Should I download all the 32 bit version of W2K3 only

to run the adprep utility? Is it adprep available for download? Where? Can I

run adprep.exe 64 bits from W2K3 to prepare the AD that resides on a 32 bits

W2K server?

 

Any hint is welcomed

Thanks

Sammy

The schema updates for 2003 R2 are the same (v31). What you need is the

correct version for the schema master you will be executing the adprep

/forestprep. In this case, the 2000 server would need the 32bit of 2003 R2.
