finally i manuallly updated one domain controller, where is a new service called WDS which can help deploy Windows Vista in the company, i don't think we need Vista in not far future,but , the service was there included in sp2.

after the apply sp2 the remote install service got problem, it tells "file not found". is microsoft wiping RIS out of server? or it is a bug?

i downloaded the big image which is 1015MB in size in acordance to the WDS help files called WLHAIK(Windows Automated Installation Kit) from microsoft and imported the WIM image from the winpe.cab insite the DVD image. the RIS went back.

there is an security issue, the client computer can boot from network without any authentication from WDS server and see the local hard drive data.
