Page cannot be displayed

Hi Justin,

The website is accessed by the IP Address. When both nics are enabled
http://localhost isn't even available but the second you disable the second
nic it is?

I know it doesn't make sense but that is what happens.

are you able to ping both nics ok from another machine?
did you make any changes to IIS? perhaps once you enable the second NIC
restart IIS?

that is just really odd because technincally when you use localhost it
resolves to 127.0.0.1 which is a special loopback address and should have
nothing to do with either nic.

it could possibly be an issue with the NICs conflicting in some way because
thats just not normal at all.

I guess what i would do is enable both NICS, reboot the box, and run a
netstat -a at the command prompt. you should see, for a local address,
server:http in there, some times with dual nics if its open on one ip and
not the other it will show the ip instead of the server name. that might
give us some indication as to whats going on here..

Hi Justin,

Well this is odd. Last night the website just wouldn't work at all even
though all of the services were started. It didn't matter if one or two of
the nics were enabled it just wouldn't work.

I rebooted the server overnight and now the website is working with both
nics enabled?

I'm guessing this must be some kind of memory leakage and that the enabling
and disabling of the second nic was just a red herring?

I'm not familiar with memory leakage issues so I'm not sure where to begin
in tracking that down.

I am thinking its probably the AV software as the version was updated
recently but I can see nothing on Trend's site to indicate this.

well if you bring up task manager and you can watch IIS grow and grow and
never release any memory, then, it could possibly be a leak... but i doubt
this would be the results of that. I think i would clean up your
connectivity issues before you try to figure out the IIS part. I would try
some of the things i had suggested below to get this working.

Also, if you have dual nic's make sure only one of them has a gateway. if
both have gateways set you run in to a problem.

try the tests below and let me know the outcome.

from your workstation
ping both interfaces via ip
ping via name

from the server
do a netstat -a and look for the http listening port

from your workstation
try to open the website root via both IP's and also by name
use telnet to connect to the webserver (telnet server 80)

Hi Justin,

Well this problem seems to have been resolved by installing a patch for
Officescan 8, even though the site never gave any indication that this was a
known fault.

IIS has been working fine with both nics enabled since last night's reboot
whereas before it never labut I'll certainly update you if the problem
reoccurs.

I always doubted that something was wrong with the networking setup as it
had been working fine for around 2 years before upgrading the AV software,
the other suspect was SP2.

This was a strange one though.

Hi Justin,

As suspected the problem has re-occurred.

Netstat -a shows:
TCP xxxx-xx-xx:http xxxx-xx-xx.xxxxx.nhs.uk:0 LISTENING
TCP xxxx-xx-xx:epmap xxxx-xx-xx.xxxxx.nhs.uk:0 LISTENING
TCP xxxx-xx-xx:https xxxx-xx-xx.xxxxx.nhs.uk:0 LISTENING
TCP xxxx-xx-xx:microsoft-ds xxxx-xx-xx.xxxxx.nhs.uk:0 LISTENING

Only one nic has a gateway and is accessible from my desktop

I can ping one nic from my desktop.

The second nic is used for backup and can be pinged from the backup server.

The website is set to use only one ip, not all unassigned.

When I try telnetting to the ip used for the site it kicks me out as soon as
I try to type anything.

Pinging via name is successful.

Disabling the second nic has enabled the website again! The day before
yesterday it wouldn't work without a reboot!

I hope you can suggest something as this is extremely frustrating and I
can't keep rebooting the server or disabling the nic as it's used for backup.

so the interesting part here is that a telnet connected and kicked you
out... you'll want to look at the IIS logs now to see why it kicked you out.

the logs are located at C:\WINDOWS\system32\LogFiles\W3SVC1
try the telnet again and then look at the logs. it should give some info as
to why you are being rejected.
