could not resolve the Central Authetication Server

[Joanna Villarroel]

Hi

A friend of my sends me a Word file (infor.doc) time ago.
When I'm trying to open this file I get the following
message:

InterDrive Client could not resolve the hostname 'endor'
that you specified as Central Authentication Server. this
server is unavailable or does not exist.

You will not able to connect NFS drives or printers until
you specify a valid authentication server.

Please, does somebody now how to change this Authetication
Server parameter so I can open the file?

My friend is not longer available so I can't ask him
another file without this authentication settings.

Please I'll apreciate any help here!!
