Installation Repo Vs. Software Repo?

I’m trying to set up a PXE Boot Installer for Linux. The problem I’m having right now is that our standard repo that was have set up (http://MYHOST/repo/$RCE/SLES11-Online/sles-11-x86_64/) doesn’t seem to be working as an install point (I keep getting “no repository found”), even though it works great as a means for a software repo (Its used by several hundred other servers)

Is there a difference between a software repository and an installation repository?

Thanks in advance!

From the fact that your repo URL looks very strange to me and contains the term SLES I deduct that you are talking about a SLES installation. Now these are the openSUSE forums.
While SLES/SLED users might get usefull help here (after all Linux is Linux), you might consider it being more usefull to go to: SUSE Linux Enterprise Server (SLES) - NOVELL FORUMS
