SYMPTOMS

If applications that are running on Application Center 2000 servers use the DllGetClassObject function or Component Categories Manager, these applications may fail with one of the following errors:

0x80070005 Access is denied

-or-

Permission to use object denied

CAUSE

Application Center 2000 tightened the security settings for all its component class keys and associated CLSIDs under the HKEY_CLASSES_ROOT registry subtree. Only the following accounts are allowed access to the affected keys in the registry:

Administrators
System
ACA_XXXX

Processes that attempt to touch the affected keys without appropriate credentials will fail with error 0x80040005 (Access denied). This usually affects those processes that use Component Categories Manager or the DllGetClassObject function.

For example, the Component Categories Manager's ICatInformation interface fails in the EnumClassesOfCategories method when it is called from a process that is not running under an Administrator's credentials:

STDMETHODIMP CExample::Example(BSTR sID)
{
...
CComPtr<ICatInformation> pCatInfo;
hr = CLSIDFromString(sID,&clsid);
hr = CoCreateInstance(CLSID_StdComponentCategoriesMgr,NULL,CLSCTX_INPROC,IID_ICatInformation,(LPVOID *) &pCatInfo);
/* EnumClassesOfCategories would fail with error 80040005 on an Application Center 2000 cluster member */ 
hr = pCatInfo->EnumClassesOfCategories(cImplemented,rgcatifImpl,cRequired,rgcatidReq,ppenumCLSID);
...
}
