Link problem using a string to class map

Hello,
using the interface given below, i'm getting 2 link errors indicating unresolved external symbols.
I'm using C++ in VS2003. What is the problem with the missing externals?

Slice definition:
module WGICE
{
class PersistentUserAccount
{
string name;
string password;
string email;
};
};


Slice Freeze command:
slice2freeze -I$(ICE_HOME)\slice --dict StringPersistentUserAccountMap,string,WGICE::PersistentUserAccount PersistentUserAccountMap PersistentUserAccount.ice


Linking libraries:
iced.lib iceutild.lib freezed.lib libdb42d.lib


Error message:
PersistentUserAccountMap.obj : error LNK2019: Nicht aufgelöstes externes Symbol

Thanks for any help!
