Server 2008 rejects connection that Server 2003 accepts

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?

Either sounds like an SMB v2.0 issue, which was introduced in 2008

or
Support for NTLM, which, as Microsoft likes to do, is disabled by default in 2008...

OK, self-solved.  The issue was to do with NAT port mapping. I had mapped port 3050 on IP address 1 through to the 2003 server, but forgotten to do the same on IP address 2 where the 2008 server lives.

Apologies for my stupidity!

Thanks to colst for the suggestions, which I implemented, and which made me think further about what could be the problem.
