Windows Server

Keith Trahan · Guest

I am in the process of switching my PPTP VPN server for incoming remote
access, from Windows 2000, to Windows 2003. I have everything setup , and I
can log in and see about 50% of the resources on the LAN. My results are
very sporatic, I can ping many machines, and many others I cannot. The LAN
is a flat subnet, and the only router, besides RRAS, is only used for
internet access.

My setup is a Windows 2003 Standard Server with 2 NIC's. I have it setup to
receive traffic on one card, and talk to the internal LAN on the other.

Here are some examples of what I'm getting:

AS you can see, I can ping 192.168.10.10, but cannot ping 192.168.10.14, but
sometimes onthe machines I cannot ping, I get one response and the rest time
out. I'm not sure at this point how to trouble shoot this, because it is so
intermittent.

Thanks for your help.
