Name as blank to join .mdw using WorkGroup Administrator

[vtreddy]

Hi All:

I've installed Access 2000 on my windows 2000 server, logged on to the
machine as administrator,I would like to join new security group .mdw file
using Workgroup Administrator,when I run Workgroup Administrator the Name
and Company fields are showing blank,when I click join , it is showing a
message box that you have successfully joined the workgroup defined by the
work group information file,

How can I get the real values,like:Administrator,company names instead of
blanks in Name Filed and company , Can any one help on this

Thanks in advance,
VT
