The View Mail in Windows XP works well but in Windows 2000 we need permissions of local Administrator of the machine, The Event Viewer following this error: Is not the description of Id. of event (101) in the origin (CiscoUnity_AvCs). It is possible that the local equipment does not have the information of Registry or archives DLL of messages necessary to show messages from a remote equipment. The following information is even VMO Error: HRESULT 0x8000FFFF, E:\Views\CU220.127.116.11\un_Client\VMO\Ext\CmdExt.cpp, 1702. Can I help to find some solution so that it works with a user estandar without giving the permissions him of local Administrator of the machine.
