Error in ODBC Connetion

I had in a customer a ODBC connection to the database sql
in which I modified the client configurations the
connection I took off the option to determine door
dynamicly and placed the 1433 but it gave error and after
this exactly placing again to determine door dynamicly it
gives always error and it does not function i remember
that before this it was to function perfectly. The error
is:
Error in Connection:
SQLState: ' 01000 '
Error in the SQL Server: 10061 [ Microsoft][ODBC SQL
Server Driver][TCP/IP Sockets ] ConnectionOpen(Connect()).
Error in Connection:
SQLState: ' 08001 ' Error in the SQL Sever: 17 [
Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]O SQL
Server does not exist or the access was refused the
computer in cause is with all the right definitions of
net, has access to the server... Please help Me! .J=E1 tentaste fazer um ODBCping? J=E1 verificas-te as permiss=F5es?
