485 back ground check 問題

I filed I-485 on 12/15/04, CSC , ED based
FP 3/16/05

Still waitting, inquiry CSC, they sent me a ltr on 8/3/05

"The processing of your case has been delayed. We are currently awaitting the results of required security checks on this case. These background checks are required of all who apply for the immigration benefit you are seeking...."

I read privious email. Back group check is not name check. Any one can advice How I can check my "back ground check" status?
name check 和 back ground check 是不同的嗎？ 應該去哪查呢？

Thanks a lot.
