Hi

looking for some advice...

Running Config Mgr 2007 R2

Rebooted the DP and when it came back up WDS wouldnt start. i removed PXE Service Point and removed WDS Role, re-installed WDS role and PXE Service Point. 

WDS started ok since then i am unable to add/remove boot images to the distribution point stuck with Removal Retrying or Install retrying.
