Hi All, I have done OSD successfully on test VM. VM is installed on same SCCM server. Now I am trying the same on Physical machine. When I boot the Physical system with PXE boot its taking more than 30 min to boot, same is working fine on VM. I have tried below with no success. 1) http://www.windows-noob.com/forums/index.php?/topic/2136-slow-pxe-booting/ 2) http://blog.danovich.com.au/2011/07/28/slow-sccm-osd-tftp-pxe/ Currently I am looking for http://technet.microsoft.com/en-us/library/cc731245(WS.10).aspx#BKMK_41 but I am not able to find any file with the name of "default.bcd" in remoteinstall\boot\x86 folder Need your help into this Please suggest if any log file I need to refer for this.. Thanks in advanced! Regards Rushikesh..

We experienced a similar issue and the cause in our case was that our Cisco switches did not have PortFast enabled.

If you are running Windows 2008 server then you need to ge the hotfix from MS. None of those fixes you can apply yourself from those articles resolved it for me until the hotfix was applied. I had a PXE on Server 2003 and 2008 and when I was booting from 2003, there was no issue and on 20008, it would take forever and eventually fail. Here is the article that references the issue. http://support.microsoft.com/kb/975710

What you're actually talking about is the TFTP transfer of the boot image after the system PXE boots. There can be a lot of different reasons for this including your actual network (as Eirik pointed out), the TFTP block size (from danovich's blog post and Windows noob), and others. Also note that this initial PXE/TFTP process is completely controlled by the NIC on the destination system. I have seen greatly different TFTP transfer speeds between different hardware models on the exact same switch port which directly points to the NIC as the culprit. Thus upgrading the BIOS can greatly improve performance. Have you tried a different model on the same switch port?Jason | http://blog.configmgrftw.com | Twitter @JasonSandys

Thanks for all your replys...... I will try with different hardware on same switchport also i will try for the hotfix...... I will chk for PortFast option lat as it will take more time consuming coz I have to followup with the respective team for the same will update the status here.Regards Rushikesh..

Can you get access to a switch on that network which has very very basic configuration? That way you'll be able to count in or discount the switch config. I worked with a customer who was seeing horribly slow TFTP performance and certainly PORTFAST and a lot of ACLs on the port were the villains of the peace

Hi, I have tried to boot a different hardware from the same switchport & its getting booted within a minute (Even its not showing a line for loading boot.sdi, its very fast booting )..... Problematic hardwae is Intel & working hardware is Gigabyte.... Alter - I will check for your suggetion & update... Thanks.Regards Rushikesh..

That pretty much narrows it down to the problematic "NIC" and eliminates all other possibilities. Have you tried upgrading the BIOS on the NIC?Jason | http://blog.configmgrftw.com | Twitter @JasonSandys

Hello All, Sorry for delay in response.... I assume that BIOS upgradation is a critical task, so I am little bit scared to proceed with this.. Still I will try this out on any spare system (Which is not much important in network) in future. Thanks for all your replys & great full help. Regards Rushikesh..

It's not a "critical" task, but if it fixes your problem, why wouldn't you do it?Jason | http://blog.configmgrftw.com | Twitter @JasonSandys

I'd be interested to hear how you resolved this as we are having the same issue.Chris Bilsborough UK NHS Support Technician

Me too. We have the same issue as topic's author. Difference between copying .wim in WinPE on VMware VM and physical PC is seven times. PC uses only 40 Mbit/sec on Gbit LAN. Inside Windows 7 copying works well. http://sccm.com.ua/

Hello frainds, As I am working away from my office for a project, so not able to check.... I will definately check it & update the status here.. Thanks for all your reply's!Regards Rushikesh..

In our case we enabled BITS, HTTP and HTTPS in distribution point properties. Speed in WindowsPE changed from 40 Mbit/sec to 900 Mbit/sec (copying using HTTP instead SMB).http://sccm.com.ua/
