Random Stops

[Branin Lippincott]

I have a very strange problem. We used to run the eval version of ISA
Server and everything was fine. We recently installed Windows 2000 Service
Pack 2 and the real version of ISA Server and ran into problems (detailed
below). We then formatted the server and started from scratch. The only
things on the Windows 2000 Server are ISA Server, Service Pack 2, the
Critical Fixes from WindowsUpdate (as well as most of the rest of the
WindowsUpdate downloads such as IE 5.5, DirectX 8.0, etc...) and DNS Server.

We are publishing an internal web site (http and https), as well as VPN and
an internal mail server. Everything works great for a while. I can reach
our internal web server from outside the company (both http and https); I
can send email to and from the company, I can access the web from inside the
company, I can access our DNS server from outside the company, etc...

Then the problem happens. Roughly a day after I install ISA Server, we lose
all incoming activity. I can still access the web from outside the company,
but noone outside the company can access our web sites, send email to us, or
get our DNS information. There are no error messages in the event logs, nor
in the ISA logs. If I then setup a packet filter to open all ports,
everything starts working again. If I then remove the packet filter that is
opening all the ports, everything continues to work, for about a day. Then
the problem happens again.

Is anybody else having this problem? Does anybody else know what could be
happening?

Hi,

We had huge problems with stopping of services before.

I dont know if this will apply on your senario, but at least it did for us.

We had problem with SMTP, DNS and services like that stopped, no reason, no
event log nothing, and we found out that it was because we published the
same service twice.

For sample, One internal computer, 2 external addresses on the ISA server,
publishing DNS on the both external adresses. But both of the request was
aiming for the same internal server.

That caused the DNS service to stop, and with it, SMTP went down.

When we re-configured the ISA to point to to diffrent servers internally,
the problem went away.

I dont say that this is the same as you have, but the regularity that it
stops is the same, sometimes it run for one or two days, sometimes it
stopped after a couple of hours.

Regards
Fredrik

Thanks Fredrik, but I've checked our system and this isn't the problem. Any
other advice?

Having the same problems... same setup
and other problems such as running a bandwith rule that uses user accounts,
then the firewall service runs for max of 1 hr before restarting..
Think i need to setup a scheudle to restart the server every 12 hr to keep
it working... not my idea of 99.999%....
cheers

Got similar problems - every once and while i have to disable/enable one of
the NIC's.

Everything works for a while and then...:(

I am having a similar problem. My ISA Server is a stand alone server in a
WinNT domain. The only strange message I get in the Event Log is that the
server has waited 960 seconds/minutes and can not reach the domain
controller. I don't know if this is linked to the server stopping inbound
connections, but a reboot of the server seems to get us reestablished. I'd
be very interested in finding out what the problem is.

Thanks,

Greg

Now that's strange. After my ISA Server got destroyed God knows why ("not a
valid win32 application"), i installed Winroute Pro. It has the same
problem. Every once i a while it just stops everything and needs rebooting
the whole system!!
I am beggining to think that all this is an Win2K SP2 result and NOT the
firewalls! I will uninstall SP2 to see what's going to happen.
