I have install the SQL Server Enterprise Manager on a Windows 2003 server with ISA 2004 and I try to connect two different SQL server 2000
One I can reach the other one I receive the message "Timeout expired"
With the same user from my PC running Windows XP I connect in the two SQL server
From ISA server I can ping the two SQL server and from the two SQL server I can ping the ISA server
With ODBC I can connect if I choose Name pipes its work fine, when I try with TCP/IP it doesn't work
I verify using server network utility but TCP/IP on the server are enable.
The strange is that one time I can reach the server but five minute later I have the error on the SQL Server Enterprise Manager that you find on the attached file
I try with SQL Query Analyzer to connect with a user that belong to the group domain admins and I receive this error:
Unable to connect to Server "ServerName":
Server: Msg 17, Level 16, State 1
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]SQL Server does not exist or access denied
this error I have from my ISA2004 server
from my PC running windows XP I don't have this problem and I use the same user
