<p class="MsoNormal"><span lang="EN-US">10.1.2.3 is the PVS server and ARDBP32.bin is the Citrix boostrap that intercept BIOS interrupt 13 to request the PVS server for missing blocks to be streamed<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">The PVS bootstrap always starts correctly but i’m having a random problem with OS streaming : sometime, the windows boot hangs. The problem does not appear on the same machine each time. If I configure DHCP so that the
machine contacts the PVS server directly, the problem never occurs (but I can’t stay with this configuration because I have to redirect to different PXE environment).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I also tried different command line (autoreplace, autofree) but no change. Even tried PXEBS instead of direct tftp chain, still no change.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I suspect a memory conflict between iPXE and PVS (ARDBP32.bin). I have opened a ticket at Citrix, but is there a way to diagnose what happen and if there is a memory conflict ?<o:p></o:p></span></p>
