Deleting ID adress from Search Option

Hai!!

Here, iam facing a problem.. My OS is Windows 2000 Advanced Server. When I typed an IP adress of a system to find it from Search, the IP adress is storing in the search list. Iam unable to delete it.. Is there any possibility to delete those stored IP adresses from the search options??

I will be thankful if it is answered as early as possible…

Yours
