Hello Guys Sorry, but i dont know where to post this problem. Since i was refering to the MSFN Unattended XP guide, i thought of posting the issue here. I was sucessful in integrating the hotfix, service pack, also tried to integrate two application using RunOnceEx.cmd. The issue i am facing now is when i make a Boot CD using the method suggested in the guide (CDImage Gui or Elder Geek Method) i am facing a strange issue. The settings are done as per the guide. Issue 1 When i use Cdimagegui to make a boot cd, the file name say for example RunOnceEx.cmd is turned to RunOnc~1.cmd like the long files names are turned in to ~1.extension as a result i am not able to install application using RunOnceEx. Issue 2 When i follow this method i am not able to boot and i get a error saying Code 5 and the OS Dont boot. Please help me out as where i have gone wrong. Thanks In Advance Happy Easter Regards Dragon
