Can you make some sort of canonical test-rig from the command-line?
Even a perl script [any perl-mongers got an example?]

Access Denied can be a host of things, client or server side.
- user/account can only make one connection at a time
- corruption of account details (protocol negotiation fails?)
- client m/c is now on a different subnet (host not allowed)
- routing issue with lost return packets? [not this time]
- a change in the server config...
- ODBC version changed on server? might work VB/Access and not yours.
- Reverse DNS lookup failing on server? Or other brain-dead 'check'.

Maybe tcpdump on the link looking at a connection that works and the one
that doesn't might tell you some more.

All the best with it.
