PreCompile header in Vistual studio 2005 problem

I have 2 projects. Both have the setting for Create/Use Precompiled Header set to "Use Precompiled Header (/Yu)"

I deleted a file in both projects. One com开发者_开发问答piles successfully but the other generates an error

Error   2   fatal error C1083: Cannot open precompiled header file: 'file.pch': No such file or directory

Have you tried "Rebuild"? An ordinary Build sometimes gets messed up. Also, is it really file.pch?
