If the identifiers are for the same type of resource, then obviously
there's a problem. If they're for different things (such as a menu
item and a string) there shouldn't be a problem.

In addition to what Mr. Lowndes said:
Controls in different dialogs can have the same identifier value.
For instance, say I have two dialogs:
#define IDD_MOVIE 101
#define IDD_ICECREAM 102
Each dialog has a control that show a picture:
#define IDC_MOVIE_PICTURE 1001 // used in the movie dialog
#define IDC_ICECREAM_PICTURE 1001 // used in the ice cream dialog
This should work ok.
You could even just have one #define that is used in both dialogs:
#define IDC_PICTURE 1001
but this might not be a good practice from a software engineering
perspective.
