Question : cannot execute the NWAdmn32.EXE ?

I try to install Netware5.1 and i am new on Netware, after install it , i would like to create user in Netware, but when i go to console => my network => tree,   it prompt Tree , context, user name , password, i try so many times to enter, but  still cannot enter the tree
For example
the tree is called      " Novell "
O( Organisation) is called  " 123 "


then how can i enter the tree?
i try all are  not work                 Tree        Novell           or 123_Novell     or  Novell
                                     Context        123             or 123.Novell      or O=123
                                      User Name    456             or 456.123        or CN=456
                                      password      456



After reinstall it, i can enter NDS tree to create object in Netware 5. However, i want to enter Netware Service in Microsoft Windows and i can install the Netware Service for Microsoft Client. But I cannot execute the NWAdmn32.EXE which file is in NW:\sys\public\Win32 directory.
IT said i miss the .dll file and prompt me to reinstall it, but i dont know where can i find this program because i cannot find in the Netware CD.
Anyone know how can i do and solve this problem?
thx everyone to reply in advance

You cannot run the later versions of Netware requestor in the OS/2 Win compatibilty 'box'. There is a special native OS/2 Netware requestor that can be found on the Novell site -- I believe it's not supported anymore but I used it against a Novell 5 network sucessfully at my last job. I think the Novell OS/2 Client has a very low version number 2. something -- but it's the last(?) one they made. The client contains special dll's that will let you access the Novell network from OS/2's Dos/Win 'boxes' too.
Hope this helps....
