SCCM 2007 PXE service point not selectable

Hi

I have a secondary SCCM 2007 site where PXE setups never really were needed and probably never worked.

After trying several workarounds I gave up und removed the PXE role and following WDS from the server.

After a reboot I installed WDS again but got stuck installing the “PXE service point” role again.

The “New site role wizard” only offers me these roles:

Are there any logs that can tell me what’s going on here?

Thanks
