I have a connection string in a Visual Studio 2008 apps querying a Firebird SQL database.
It works perfectly when the target IP address is a Server 2003 machine. The exact same connection string fails to connect when the target server is a Server 2008 machine.
The string is: <add name="connectme" connectionString="Server=nn.nn.nnn.nnn;database=d:\\support\\checkintest\\diary.gdb;userid=sysdba;password=masterkey" providerName="FirebirdSql.Data.FirebirdClient"/>
I have tried disabling windows firewall
I have tried disabling Symantec endpoint protection firewall
I have added firewall rules to allow the source IP to be permitted to access the target server
I have added firewall rules to ensure that port 3050 for firebird is open on the public WAN
What could be the issue?
