Ok we have tried everything we can think of, but can only get this working for a few images and it chokes again.

We have a zen 7 installation on OES2 servers both fully patched. However, whenever we try to image we might get two or three images out of it and then the server will hang at the preboot policy section of pxe. The tftp logs seem to point at a network issue, but nothing else seems affected. We removed and reinstalled zen 7 and it worked for awhile this morning and is back to the same thing.

Any thoughts?
