Solution:

This issue occurs because setup is looking for more media.

If you are installing from CDs, the CDs have to be local. Using a network share for CDs won't work because setup.exe doesn't recognize that it is installing from a CD and won't ask for the Media switch when installing Tools.

It's okay to share a DVD since all of the information is on the one disc and setup can find it.

So you've got some options -
1/ Install with the CDs in the local drive (swapping as necessary)
2/ Copy both CDs to a share, using the name of the cds as the folder to copy in to
3/ Burn a DVD - put CD1 in the a “Servers“ folder, and CD2 in a “Tools“ folder.
4/ Install everything except tools from the Shared CD1, then install just Tools from Shared CD2.
