Re: VPN connection drops every 3 minutes

Is this the only forum you have tried for a solution?

I have looked everywhere I can think of to try to find the answer - but so
far without success.

Do you have colleagues who also use the same VPN to the same exchange server
who are able to connect and stay connected - or is it only you who has the
problem?

In my case there are at least five other staff using the same system who do
not have the same problem as me.

There must be a way of refining the problem down in some way so that the
solution comes down to a specific setting or piece of software.

Thanks - John
