The System Configuration framework is a C api, so it's a little bit messy, but this should work ok without leaking:

#import <SystemConfiguration/SCNetworkConfiguration.h>

SCDynamicStoreRef storeRef = SCDynamicStoreCreate(NULL, (CFStringRef)@"GetWorkgroup", NULL, NULL);
CFPropertyListRef global = SCDynamicStoreCopyValue (storeRef,CFSTR("State:/Network/Global/SMB"));
id workgroup = [(__bridge NSDictionary *)global valueForKey:@"Workgroup"];
NSLog(@"Workgroup: %@", workgroup);
CFRelease(global);
CFRelease(storeRef);
