I have to connect database remotely. For that I have done all the settings using SQL server configuration manager. I have set port number as 1433 the default one. Also added this port number into windows firewall exception list and turned it on. Now in my connection string, value of the "server" parameter is only "IPAddress". But while loading crystal report into CrystalReportViewer control it ask me for the Password to enter. I have set all Connectioninfo to the CtrystalReport at runtime, but till it ask for password . How can I solve this problem? If I use "IPAddress,1433" as the value of server parameter, it works fine. But as per my knowledge, 1433 is default port and need not to be include in the connection string. please help if anybody knows the solution. Thanks.
