The computer associations are not created by the import computer information wizard in SCCM 2007 Service pack 2

If you are deploying operating system to unknown computer and you are facing a problem and getting some error----

1-No action found for boot device,

means your system is not getting PXE and you WDS service is not running on server, though you have configured all task sequence.
just restart WDS services and reconfigure your PXE,


2-The computer associations are not created by the import computer information wizard in SCCM 2007 Service pack 2

You click the following item in the Configuration Manager console:
Computer Management\Operating System Deployment\Computer Association

-->You run the Import Computer information Wizard to import new computer information.
In this scenario, the computer associations are not created when the new computer information is imported. Therefore, there is no new node in the computer association list.

that mean you server is not updated with
the kb989270 patch, so you must have to install hotfix for more information see http://support.microsoft.com/kb/980270 which should fix the problems with objects in the collections

History of Dennis M. Ritchie

Dennis M. Ritchie

born Sept. 9, 1941 in Bronxville, N.Y., and received Bachelor's and advanced degrees from Harvard University, where as an undergraduate. He concentrated in Physics and as a graduate student in Applied Mathematics. The subject of his 1968 doctoral thesis was subrecursive hierarchies of functions.

He joined Bell Labs in 1967, following his father, Alistair E. Ritchie, who had a long career there. His most visible public accomplishment was as co-author of The Design of Switching Circuits, with W. Keister and S. Washburn; it was an influential book on switching theory and logic design just before the transistor era

Early in the development of Unix, he added data types and new syntax to Thompson's B language, thus producing the new language C. C was the foundation for the portability of Unix, but it has become widely used in other contexts as well; much application and system development for computers of all sizes, from hand-held to supercomputer, uses it. There are unified U.S. and international standards for the language, and it is the basis for Stroustrup's work on its descendant C++.

Awards: ACM award for the outstanding paper of 1974 in systems and languages; IEEE Emmanuel Piore Award (1982), Bell Laboratories Fellow (1983); Association for Computing Machinery Turing Award (1983); ACM Software Systems Award (1983); C&C Foundation award of NEC (1989); IEEE Hamming Medal (1990). He was elected to the U. S. National Academy of Engineering in 1988. In April 1999 he received the U. S. National Medal of Technology. These were all awarded in conjunction with Ken Thompson.
