SQL/BDE Trusted SQL Connection

Hi All,

I have written a system in Delphi 5, the database backend being SQL Server
7.

I connect using the BDE ....... There are 40 user workstations that
successfullly connect to the server and the application runs with no
difficulty.

2 machines were redone, FORMAT & RE-INSTALL.  The operating System loaded is
Windows 2000, BDE is loaded but the application refuses to connect
generating an error:

LOGIN INCORRECT ....
LOGIN FAILED
Unable to establish a trusted sql server connection.  User "MYNAME"
incorrect.

I use the follwoing code to connect to the db:

   Database1.KeepConnection := False;
   Database1.Connected := False;
   Database1.params.clear;
   Database1.params.Add('USER NAME=');
    Database1.params.Add('PASSWORD=');
   Database1.params.Add('DATABASE NAME='+edtDatabaseName.Text);
   Database1.params.Add('SERVER NAME='+edtServerName.Text);
   Database1.params.Add('MAX QUERY TIMEOUT=-1');
   Database1.params.Add('HOST NAME=' + UpperCase(BDEInfo1.NetUser));
   Database1.params.Add('TIME OUT=-1');
   Database1.Connected := True;

Any ides ??
