These error messages are no originating from the firebird server. They are
coming from the application. There appears no ability for the application to
stop what it is trying to do and wait, instead it keeps firing up.
10054 errors are sometimes associated with faulty NICs but sometimes also
with network disruption as you suggest. The pictures you sent suggest there
is more than one application/service running, and SMS service, a backup
service of some kind AND the application - I can't tell which is causing
these popups. The tital says 'background SMS' - what's that?
We can normally help an application developer sort out these sorts of issues
but with no real info on the applicatoin archtitecture, it's pretty hard to
guess.

When a TCP connection is broken between application and FB server, there is
no recovery normally, it's broken for good til you reconnect from another
process. It's possible for the server to not notice that the network is down
for a split second but in my experience a lost connection is fatal
immediately.

I have replace the on-board NIC with one in a PCI slot. Still the same issue.



There are two programs running.. background process and SMS for vetlink (the main app). They have to run at the console level (administrator). Also there is a DOS based backup program that has to be run (manually) at that level also. When you say it has to reconnect from another process, what do you exactly mean?
