I was going to say sounds like PXe is not installed properly. Once you get up to speed with altiris you will want the client of every workstation on your network and wonder how you did without it! It is THE best management tool we own. Jim > wrote: I've done a full reinstall of Altiris and the PXE service is now behaving. What's more, my test terminal has seen it and responded accordingly. I may actually have turned the corner on this one. -----Original Message----- From: Angus Macdonald [mailto:Angus.Macdonald@xxxxxxxxxxxxxxxxxxx] Sent: 25 January 2005 09:53 To: thin@xxxxxxxxxxxxx Subject: [THIN] More Altiris headaches. It's lucky I'm not particularly hirsute normally, because I'd be a lot less hairy now if I was? I'm trying to use Altiris Express 6.1 to manage an impending batch of 250 HP T5300 and T5700 terminals. I can happily configure them, remotely control them and do anything except image them. Jim and others have given lots of help regarding PXE and Bootworks and I feel I'm nearly there but I just haven't been able to get the terminals to see the PXE server. this morning, I've discovered that's probably because the PXE service on my dedicated (VMWare virtual) Altiris server terminates a few seconds after it is started, with a service-specific error 1003 in the system log. The application log has "ERROR: Unable to query master PXE proxyDHCP for multicast Address Allocation parameters". This is my only PXE server and as far as I can tell Multicasting is disabled. I've googled for the error message and come back with one, unhelpful, hit. Can anyone suggest somewhere to start looking? Angus
