this is not related to OS
i remember i used to ask this question before , but i can't find it anymore&i don't known how to find it , for this time , i want to say i have found the rootcause, i'd like to share with all of you;
this is related to WPE (windows preinstall environment) not that hot ,seldom people will use this;
for athores lan chip has high fail rate issue--TFTP fail, while the client try to PXE boot from lan, and we ask the vender for help, they send us a patch issued by MS(http://support.microsoft.com/default.aspx?scid=kb;EN-US;2673007)
to solve this issue: after adding this patch , the issue really goes;
and when WPE 4.0 (6.2.9200) phasing in for pilot run, we encounter a strange issue after the client load the boot.wim from WDS server successfully, when the client try to boot from local, it will show 0XC0000428 directly;
finially we find the rootcause is the patch added to solve TFTP fail issue;
is there anyone can explain this to me, it will be appricated!
