assemblies not updating

I mated two assemblies that were made of many smallerassemblies. Everything went together nicely. However, when I go toopen the larger assembly, SW has trouble finding some of the partsthat were part of the smaller assembly that I brought in. I amaccessing this off of a server and the program is looking for theparts in the hard drive of the computer where they were originallydrawn and assembled. I can go in and manually find the first part,and then SW finds all remaining. I have saved, reopened, andeverything else I can think of. HELP!!SolidworksAssemblies
