getting the erro while deploying OS using sccm . failed to send the DDR (0x80004005) Please let me know what the error about and its solution.

We need a lot more context than a simple generic error message to help. Things like what task is this occuring on, when do you see the message, how did you create the task sequence, how did you create the image being deployed, etc. ? Also, have you reviewed smsts.log on the target system: http://blogs.technet.com/b/inside_osd/archive/2007/12/13/troubleshooting-tips.aspx ?Jason | http://blog.configmgrftw.com | Twitter @JasonSandys
