esebcli2 HrESEBackupPrepare

[btaber]

I am trying to complete a custom backup solution. I am using the esebcli2.dll interfaces for this. I am able to call MNUBackupRestoreGetNodes with no problem. When I try to prepare the backup using HrESEBackupPrepare, the command fails with "An attempt was made to reference a token that does not exist." I have found many posts regarding this, but no solutions. Does anyone have any ideas?

Here is some of the code:

HrESEBackupPrepare fnHrESEBackupPrepare = (HrESEBackupPrepare) GetProcAddress (hMod,"HrESEBackupPrepare"); 
ESEBackupFreeInstanceInfo fnESEBackupFreeInstanceInfo = (ESEBackupFreeInstanceInfo) GetProcAddress (hMod,"ESEBackupFreeInstanceInfo"); 


WCHAR *MyServer = L"MYSERVER";
WCHAR *MyStore = L"Microsoft Information Store";

unsigned long InstanceInfo = 0;
INSTANCE_BACKUP_INFO *aInstanceInfo;
HCCX Handle;

hr = (fnHrESEBackupPrepare) (
	    MyServer,
	    MyStore,
	    &InstanceInfo,
	    &aInstanceInfo,
	    &Handle);

if (hr != S_OK)
{
	printf("BackupPrepare Error: %-8lx", hr);
	FreeLibrary (hMod);
	return -1;
}
