Hope someone can help, running Windows2003 Server, routing between NIC1 and
NIC2 on the server, NIC2 is attached to a DSL and do not have any problems
getting to the internet on the server. The problem is the workstations will
be fine and can browse without any problems, then all of a sudden they cant.
I check to see if I can hit the remote gateway and can't , after about 10-15
mins it seems to start working again. I cannot seem to figure out what is
going on... does anyone have any suggestions?

Thanks
Gavin...
 
I suggest breaking the issue down into smaller pieces.

I'd also enable tracing for IPRouterManager, RTM , and Router.

Set the following to Enable tracing:

HKLM\Software\Microsoft\Tracing\

IPRouterManager
EnableFileTracing = REG_DWORD 0x01

Router
EnableFileTracing = REG_DWORD 0x01

RTM
EnableFileTracing = REG_DWORD 0x01

Determine where the issue lies.

When the problem occurs, can you ping the local default gateway ( Windows
2003 Server ) for the client?

You stated you can't ping the remote gateway. ( I'm assuming the gateway
provided by the ISP ), can you ping this gateway from the Windows 2003
Server with the directly attached DSL interface?

Its possible that your DSL line is flakey, in which case you need to talk
with your DSL provider.
