I have an SBS2000 installation at home on which I have just run the Remote
Access wizard. It happily lets me login via a workstation at work. But
about a day after setup we are finding here at home that workstations
intermittently cannot surf the web. The ISA client refuses to refresh at
this time (either the server is down or it is not an ISA server is the
message, although it immediately refreshes if I put in the IP no of the
server... but still no browsing.) The problem seems to go away after a few
minutes. Also we are finding that some people are having trouble logging on
here.... again an intermittent problem.

We have a fixed IP with a 56k modem here at home.

All the packet filters are enabled. I have found one warning in the
application log that isa server was dropping packets, but it does not
correspond to the times of difficulty.

Is there a common problem here that anyone is aware of? I'd be glad to hear
from you

Does your server have SP4 installed? If so that is good. Even SP3 is
ok for this article. Go to support.microsoft.com and find article
292822. The article mentions getting a patch from Microsoft. That
patch is included in SP3 and SP4. Do the edits as they are requred if
you dial into your server remotely via vpn or RAS. Your network card
(cards) should have their dns set to the ip of of your main nic. On a
standard SBS install the default server ip is 192.168.16.2. Read the
article carefully because it explains some WINS issues. Also note that
at your server you need to go into the DHCP manager and set option 46
to 0x8. If you see an article that says 0x1 is the proper setting then
the article is wrong.

Make sure that the workstations do not have any entries in their host
files that can cause you problems. Do a search for hosts and read the
files. The hosts file does not have an extension. Also make sure that
the workstations do not have manual entries for dns or wins that
poiint to any ips except the ip of your server's main nic.

Man, talk about trace along the dotted lines...! No ideas what some of that
stuff was doing! But it worked a treat. My thanks Jim, you saved me a heap
of headache.
