HI NG

We have been trying to set to Servers up to NLB, and we have tried
both unicast and multicast.
The NLB setup works fine, if we ping the Cluster adress we can
disconnect one of the servers without loosing connection. But if we
try to acces the cluster adress from a browser, we get "Internet
Explorer cannot display the webpage".

We have no internal firewall who can cause the problem, and we are
connecting from our local network so external firewalls who can cause
this.

Anybody here who knows what could be causing this

Regards JWI
 
Re: IIS under NLB

Hello,

Do you have a corresponding DNS entry ?

what about http://X.X.X.X/ with the cluster ip ?

any host header in the IIS web site ?

Yes we have a dns entry, for det cluster IP adress, and no as for now
we dont use Host headeron this IIs.
The only site in this IIS is a default.htm stating the server name.

I have just uninstalled IIS on both servers and taken them out of NLB.
Then i installed IIS again and testet it succesfully,
I then setup a multicast NLB with only one server in it, and testet
the IIS connection to the cluter adress unsuccesfully

I simply dont understand this

Re: IIS under NLB

ping clusterip
telnet clusterip 80 (do you get a black screen) ?

when we ping the cluster port everything is working, i can even
disconnect hosts without ping stops.
So the NLB is working... Sort of....
When you telnet cluster ip +port 80, it responds but throws you out
again before you can enter a command.
I have tried "get" and sometimes the command is executed, but it is
still saying, cant display webpage.

our affinity is set to single, and our port rule allows all ports to
connect to the cluster ip
