Ok so I'm a little ticked with something, but I don't know what yet.

I have an application that I've written that uses FB and IBO and it
has worked very well for the longest time. Yesterday it has stopped
working with the following error message:

ISC ERROR CODE: 335544721

ISC ERROR MESSAGE:
Unable to complete netowrk request to host "192.168.1.2".
Failed to establish a connection.
unknown Win32 error 10060

and the part that really ticks me off? I can connect to the same
database using marathon (1.6) which also uses IBO, IIRC. So I'm
pretty sure it's not an IBO problem. Anybody have any theories as to
what the problem is?

I'm trying to connect over a VPN connection, but like I stated I have
other connections working properly. And I can already confirm that
the failing application works properly on other remote databases.

ANY help would be appreciated.

Ryan.
