Hi

 

If it helps any I have found that if I stop only the firewall service on
the ISA starting the VPN connection then all works fine.

 

If anyone can explain or shed light on this....please do so.

 

Thanks in advance 

 

William

Hi 

 

Same problem on this side but my clients are Win2K servers with ISA. The
problem disappears if I stop all ISA services except ISA control. On
clients where they user Win2K Pro I got my ISP to change DSL modem and
problem disappeared.

 

Installed SUS lately, Feature Pack 1 and some Microsoft patches.

 

Any other suggestions welcome.

Similar symptoms here, similar history.  We changed T1 providers and
I've been blaming them!

 

Hadn't thought of blaming Bill.  Anybody with a clue?

Having a new problem with our VPN connections. 

Setup: ISA Server on a Win2K Server (SP3) Box.  Fairly standard VPN
configuration PPTP and L2TP (though we don't use L2TP yet).  Always on
DSL connection.

        Clients are WinXP and Win2K Pro, generally, connecting over
RoadRunner cable modems using PPTP. 

Connection goes fine but for some reason anywhere from 4-35 minutes into
the session the connection is simply dropped.  No error, no warning.
Nothing useful in the event logs on client or server - just that the
connection was dropped.  Can reconnect fine, but again 4-35 minutes
later it disconnects again.

Up until a couple of weeks ago it worked fine (for over a year).  Any
immediate suggestions? 

The only think that comes to mind here is that we have recently done
some of the "Windows Update" service packs/hotfixes on the server.  Any
of those known to affect VPN like this?
