I have three satellite servers 11.2.2 MU2 one with Win 2008 Ent SP2 and two with Win 2008 R2.

The issue is around the R2 servers and the preboot service. When imaging a machine if you go to image a second machine the PXE boot runs incredibly slow to the point of sometimes failing to download the boot\linux image (takes 15 minutes just to pull down the boot image).

If I restart the Novell ZENworks Preboot Service. It will immediately return to normal speed on the preboot image download. This issue is only with the R2 systems the standard win2008 SP2 server works correctly. All Satellites are configured the same. We have had the network monitored and this shows no sign of any issues.

Anyone come across this sort of issue.
