Can you elaborate on this? I have not found the Retro Client does 
this, but I'm on a LAN so the connection presumably exists and the 
client is happy. But if the Mac is set to 'Connect via' PPP will it 
then dial up? That might be unusual though to have the Client running 
when on a PPP dialup connection. Where's the backup server going to 

I have to say that IMO ANY software that causes these sort of 
uncontrollable dialups is seriously flawed, badly written, arrogantly 
conceived, call it what you like. If you pay for calls, as we do here 
in the UK, this software costs you money every time it feels like it. 
Since the minimum call time is likely to be several minutes this is 
not trivial and irrespective of the cost it is just not acceptable 
for a programmer to make decisions like when he will spend your 
money. I am VERY against this sort of arrogance (so typical of 
Microsoft in fact) and I'm surprised at Dantz.

Internet Explorer tries a reverse lookup on the address when you 
attempt to load a page which cause a dialup to find the DNS (assuming 
that the TCP config specified a remote DNS), yet if the target is on 
the local LAN the dialup is wasted. Worse than that, the Mac 
effectively hangs while it waits for the answer as this process hogs 
the entire CPU. When it cannot get an answer IE just carries on, so 
having the name rather than numeric address is obviously not 
important so why waste my time and money.

Stefan's problem with File Sharing is I believe the same problem - 
there's a lookup going on and if there isn't a DNS entry you're stuck 
for about 45 seconds waiting for the lookup to fail. I'm not sure why 
it occurs on the 6500 and not the G4 with the same OS though. Are 
they both pointing at the same DNS?

I have found that once I set up a local DNS (MacDNS) these long waits 
disappeared as the lookups were quickly completed and everything is 

This hogging the CPU for lookups is a MacOS thing though, not an 
application problem and BTW WiNT doesn't do it. It seems to be able 
to figure there's no response to the DNS query and get on with things 
much more rapidly and even while it is waiting you can still do other 

My major complaint is that many programs seem to be written in a way 
that assumes a permanent or free Internet connection and while that 
may be true for a lot of the US, it certainly isn't the case here in 
the UK and this arrogance makes me very angry indeed. NO application 
should EVER cause a dialup that the user has not requested or 
specifically allowed.
