Hi, I have an MFC application that displays the network adapter details.(For Ex: IP Address, DHCP Server, Lease Obtained, Lease Expires etc.) I have used WMI to get the network adapter details in my application. Following is the code snippet: IEnumWbemClassObject *l_pWmiEnumerator = NULL; IWbemClassObject *l_pClsObj = NULL; ... Execute the following query "SELECT * from Win32_NetworkAdapterConfiguration where index=7" ... //Get the value of DHCP Lease Obtained CString l_csDHCPLeaseObtained=_T(""); l_hr=l_pClsObj->Get(_T("DHCPLeaseObtained"),0,&l_vtProp,0,0); if(VT_NULL!=l_vtProp.vt) { //Sets the DHCP Lease Obtained value } //Get the value of DHCP Lease expires CString l_csDHCPLeaseExpires=_T(""); l_hr=l_pClsObj->Get(_T("DHCPLeaseExpires"),0,&l_vtProp,0,0); if(VT_NULL!=l_vtProp.vt) { //Sets the DHCP Lease Expires value } Now, when I restart the machine and execute the above code, following values are seen as output in my application on both Windows 7 and Windows XP OS. Also, it matches with the result shown when "ipconfig /all" command is executed on cmd.exe. Output in my MFC Application: Lease Obtained: 7/8/2011 3:55:07 PM Lease Expires: 7/15/2011 3:55:07 PM Output in cmd.exe: Lease Obtained: Friday, July 08, 2011 3:55:07 PM Lease Expires: Friday, July 15, 2011 3:55:07 PM However, if now I execute the command "ipconfig \renew" from cmd.exe on Windows 7 OS, following output is shown in my application: Output in my MFC Application: Lease Obtained: 7/8/2011 4:00:35 PM Lease Expires: 7/15/2011 4:00:35 PM Output in cmd.exe: Lease Obtained: Friday, July 08, 2011 3:55:07 PM Lease Expires: Friday, July 15, 2011 4:00:35 PM Can anybody please let me know why the "Lease Obtained" time obtained in my application does not match with that on Windows 7 OS? Also, this problem occurs only in Windows 7 OS and it works fine in Windows XP OS. Thanks & Regards, Ruhee Jaiswal
