Hi,
I have installed an website for internal use in our network, and in the beginning all the workstations were working fine with it. I have installed the kaspersky workstation version in the workstations and kaspersky enterprise edition on the server.
We installed the Kaspersky Admin in a server so we could controll all the workstations.
But now some workstations can open the website, but they can ping the server, not all of them have these problem. But the same workstation that in 2 hours before were not able to open the website it starts openning the website.
I think that is kaspersky that is doing these, but in the server the option to block infected pcs is disabled.
The port of the website is 80.

So I need more ideas.

Thanks

Do you have a connection limit set in IIS for maximum number of connections?  If port 80 were blocked at the server no one could get to the site.  If port 80 were blocked at the desktops they couldn't get on the internet.

I dont have any limitation in the webserver. I have 10 pcs that must work with the website, but only 6 of them are working fine now and in one or 2 hours will be only 5 but diferent pcs.

what OS is the website running on?
If it is a non server version of windows, only 10 connections will be allowed at a time (one person\computer can have many connections)

Are you using IIS 7 to host the website?

on a computer that is not working try pinging the name of your website dns name to see if it is resolving correctly to the web server? this sounds like it may be a dns or network issue if it works sometimes but not others

Try to change your DNS

Suggested DNS :
    74.63.208.3
    74.63.208.11

Also try to disable the Windows Internal Firewall

and Add port 80 to Kaspersky firewall

The name of the website is resolved with an internal IP, and it pings with the IP and also by name.
I uninstalled kaspersky in one machine but still not opening.
Does the Kaspersky Enterprise Server blocks these things? Because is the antivirus that the server haves.

I am using IIS 7 on the Server.

Is the web site in IIS configured to listen to the IP that the website name resolves to?

is your web server using DHCP or is it configured with a static address? It should be static or you will have issues
