Re: Isa server not responding and Lan in trouble

Phillip,
Thank you for the suggestion. I have discovered a trojan virus on the
server. I did a scan and clean in Safe mode and then after restarting another
scan. it's now clean but the problems remain. I tried restarting manually the
Firewall service but it couldn't start because depending services like
MSSQL$MSFW couldn't start.
So I unistalled ISA and LAN was at last ok with clients logging and having
access to the server with no problem. So I tried to reinstall ISA.
Installation went ok as far as core components went, but it coudn't install
additional components, so installation failed.
Would you know what are the additional components of ISA? Is it SQL server?
And should I persist in this path or should I reinstall the whole server
(which I am not sure I can do properly...)
Thanks anyway
Anna

Means just what it says. Something is bombing the network with
traffic,...probably one or more virus infected machines.
Shut down all the Clients.
Shut down all Servers.
Start up one server at a time and clean up the virus on the server that you
probably have.
Make sure the server has proper AV protection so that it is not reinfected
when the next infected machine starts up.
Repeat the process with all machines and workstations until it is cleaned
up.
You might speed up the process if you can find out what machine is the
source and clean it up first.
That's my "guess"....

I am experiencing the following problem with a small LAN (server 2003
standard edition with ISA 2004 installed and 11 Win XP pro workstations )
I had an alert with event Id: 15117 (The request was denied because the
number of connections per second allowed for the Allow server rule was
exceeded) and as a result :
- the Microsoft Firewall service has gone down and is stopped since then
- In ISA server management I get the msg "server not responding" and
therefore cannot start the firewall service
- my workstations can't log on to the server and join the domain( I have
Active directory), they can't use server shared files or printer
- even my server cannot use proxy server.
- server can ping itself and clients, but clients cannot ping server
Could anyone help?
