till friday 01/02/04. This morning when users are trying
to access it giveing the error Run Time Error '-2147467259
(80004005)':
Invalid connection String.

server. I changed the TCP/Ip ports on one of the server
in server network Utility to 1521 and changed it back to
1433 . nothing else. has changed as far as I can think
of.. please help THanks in advanceReply back with the connection string syntax.
