        Also, if you remove the "WHERE LogonType = 2 OR LogonType = 10" from the outer query, you can see all logon sessions, not just the interactive ones. :) Mark

              Also in this code though I have kept 'logontype' as 2 and 10 to get only active user names, but it;s returning me all users those are Disc earlier...

                    Hi Mark, I just realized that 2nd query which forms like "Associators of {Win32_LogonSession.LogonId=1121214} Where AssocClass=Win32_LoggedOnUser Role=Dependent" works for local machine but when I try to execute it on remote machine after above query executes, at next line it fails... Query execution passes but enumeration fails.. at below line, HRESULT hr1 = pEnumerator1->Next(WBEM_INFINITE, 1, &pclsObj1, &uReturn1); I have been trying different things to check out but no luck, any idea why it cud be happening or is there any change in query while running on remote machine ? Regards, Supriya Tonape

                      Hi All, For some reason, when I add the following lines, to get the StartTime property value, the get function fails. Any ideas?

                      VARIANT vtProp2;
                      HRESULT hr2 = pclsObj1->Get(L"StartTime", 0, &vtProp2, 0, 0);
                      if(hr1 == S_OK)
                      {
                      SYSTEMTIME t;
                      int res = VariantTimeToSystemTime(vtProp2.dblVal, &t);
                      }
