This is one has been eluding me for a little while now.
OK, I have two domains, in two completely different networks in different parts of the country. At the moment, the domains are not associated in any way.
I have an ISA 2000 (running on Windows 2003 standard) box on each domain. I created a two-way VPN bridgehead between these two ISA boxes. Everything works great, except:
A Sprint T1 we have at one location is flaky and has been dropping off. If this happens while our VPN bridgehead is established, we have to restart RRAS on the OTHER (the server that ISN'T having the network problems) isa box. If we don't, the demand dial interface tries to connect, and we get back a the following error:
RemoteAccess EventID 20111 A Demand Dial connection to the remote interface cle_mia_1-12-04 on port VPN5-127 was successfully initiated but failed to complete successfully because of the following error: Access was denied because the username and/or password was invalid on the domain.
Like I said, this problem goes away once I restart RRAS on the other ISA box.
So, I'd really like to figure out why this is happening, and "fix" it so that if our network connectivity drops off, I don't have to manually fix anything to restore our VPN connection.
