Hi Rick,

Unless you're using i386 machines without a math coprocessor, you should
be OK for a few days without fail over ;)

HTH,

Tom,

I am contacting them on it shortly. I tried turning off caching
completely
and still had to restart the w3proxy service this morning. This glitch
is
driving me nuts! Especially since the other ISA servers I have running
have
not had a glitch...............nuts!

I guess I could change our DNS to make the virtual name point to the
server
having trouble and take RainWall out of the picture.....I'll have to
think
on that one.....That would leave me with no fail-over at
all.......hmmmmm...If they have never run into this I may be forced to
try
it.....

Thanks,

Rick

Hi Rick,

I will be interested to see if RainFinity has some ideas. I've been
using RainWall in a number of environments and haven't seen a similar
issue. I'd be interested in how you have it configured. The thing I
REALLY LIKE about RainWall is how easy it is to setup and understand,
compared to the MS NLB. I actually find it fun to work with :)

Thanks!
Tom

Tom,

We installed the newest version of RainWall and while troubleshooting a
glitch I mentioned it to them but I didn't address it directly but I
will
today. We are not publishing anything, ISA is used for outbound Internet
access only. I can't believe that after so many rebuilds and new
hardware we
still have this trouble but the second server has never had a problem...

Thank you,

Rick

Hi Rick,

Have you checked with RainFinity to see if they have something similar
documented? Also, are you publishing any DNS servers?

Thanks!

Tom,

Thanks for the help! We went the route of new hardware and a new build
and
still the same problem. I ran a check on your suggestion and received
Zero
during both times. 

I am at my last on this one, MS can't help since we run RainWall, they
say I
would have to remove it but then there would be no users hitting it to
load
up the server anyway.....and I can't point the IP to that server only
because if it fails I'll have too much downtime switching to the
other......This is really making ISA look bad even though server #2 has
been
running without a problem....all they see is a slow to no Internet
connection.

Any ideas would be greatly appreciated!!


Rick

Hi Rick,

You'll find it in the Firewall service objects, IIRC, in the Performance
console.

Tom,

Thanks for the quick response! I am not sure what you're referring to,
how
can I set up this baseline? I might just be misunderstanding the term.

Thanks again,

Rick

HI Rick,

Get a baseline on your "Non-connected UDP mappings" when things are
working. Then get a reading when things are not working. Let us know if
you notice any significant differences.

Thanks!

Hello all,

Help!!

I have one I have been fighting for over a month, we have ISA Enterprise
Edition SP1 installed in Integrated mode on Win2K SP3 in an NT domain.
We
have two servers using RainWall for load balancing and fail-over. We
have
about 1500 users hitting the two servers.

Problem: (we are only having problems with one server) ISA will be
delivering pages with no problem and for no reason the Internet access
from
this one server slows down till it no longer serves up any pages. I have
seen many times where begin it's downhill slide by IE saying that it was
"done" downloading a page and the page is blank. Hit refresh and the
page
comes up (this does not happen all the time though, it may just slow
with no
warning). The server is not locked, we do a "net stop w3proxy" or just
restart the services and it is fine till the next day it will do it
again.

We have checked the cache, actually I have replaced the drive with a
large
drive and made the cache huge and then incrementally reduced it down to
where we are not using caching at all and still have the same trouble.
Also
tried spreading it across multiple drives.

We have formatted the box and re-installed everything, using the ISA
configuration from the box that has no difficulty.

We have all the latest and greatest patches installed.

We have replaced the NIC cards, re-installed TCP/IP, still the same
problem.

And checked about every configuration I can think of and still the same
problem.


Any ideas? Someone about to hang me on a flagpole out front if they go
through this much more.....
Thank you,

Rick
