1_ Your LABEL directive is using space characters. For the LABEL 
directive, either limit the label to unique one-word type-able 
characters, or at least replace the space characters with 
underscores.

2_ Are you sure your "bootmgr.exe" is correct? Even for a UEFI 
system?

3_ Are all those files located in the same (working) directory as all 
your PXELINUX files?

4_ Are you using the *latest* Syslinux 6.03-pre* version? At the 
moment, the latest is 6.03-pre20 (and you should avoid using any 
prior 5.xx or 6.xx version, unless specifically requested for some 
test).

5_ Regarding files from Syslinux, are you using all files from the 
same exact version? Are you using pre-built binaries from kernel.org?

6_ When you mention UEFI architecture, I guess you are referring to 
clients only (not servers), right?

7_ Are the clients really configured for UEFI mode? Is there any 
chance they could be (mis)configured for CSM?

8_ Have you tried with lpxelinux.0 instead of pxelinux.0?

9_ Are you able to successfully boot anything else (so to discard a 
possible sever misconfiguration)?


The above comments (they are not really questions) most probably 
won't resolve all the issues, but perhaps they might give you some 
basic points to consider.
