I am testing a trial version of Kaspersky Business Space Security
on our organization's PCs. We have 2 servers and can support up
to 10 workstations for our trial copy. We are using Kaspersky
Administration Kit 6.0.1572 to administer the workstations and
servers. For our servers, we are using Kaspersky Anti-Virus 6.0.3.837
for Windows Servers. For our workstations, we are using Kaspersky
Anti-Virus 6.0.3.837 for Windows Workstations.

Kaspersky has been working well on the servers and the newer PCs
we have; however we are experiencing problems with older Compaq
desktops running Windows XP Professional. If Mail Anti-Virus,
Web Anti-Virus, or Anti-Spy are enabled on the older computers,
the computer loses the ability to browse the web and retrieve
e-mail after attempting a send/receive in Outlook 2002. Internet
Explorer is "waiting for a reply" on every web site we try to visit
and no messages are able to come through when clicking send/receive
in Outlook afterwards. For e-mail, we use POP/SMTP. All Windows Updates have
been installed. The same policy is used for the working computers
and the ones that are having trouble. If I disable Mail Anti-Virus,
Web Anti-Virus, and Anti-Spy, the problem goes away. If any one of
these are enabled, the problem is back.

Does anyone know what the problem could be? Why would the same
policy affect different computers differently? We don't want to
have to disable Mail Anti-Virus, Web Anti-Virus, and Anti-Spy on
the older computers in order to use Kaspersky because we'd like
to use those components.

Any ideas would be appreciated.

Thanks,
Paul

Welcome

Install Firefox and check if it can access any website. Please inform the result.

And try separately:

1) Close all applications. Go to "Start - Run":

regsvr32 -u "C:\Program Files\Kaspersky Lab\Kaspersky Anti-Virus 6.0 for Windows Workstations\scrchpg.dll"

Open IE and test.

2) Go to Start - Control Panel - Network Connections - Right click your connection - Properties, disable "Kaspersky Anti-Virus NDIS Filter".

Reboot, check if it works.

Hi Mpsilva,

Thank you for your reply.



I followed these steps for testing Firefox:

1) Installed firefox as administrator
2) Logged in as domain user
3) opened firefox, browsed web successfully
4) checked e-mail, nothing to send/receive
5) browsed web successfully
6) checked e-mail, 1 outbound message (it appears there is only a problem when there is an e-mail to send/receive)
7) e-mail does not send
8) opened firefox, cannot browse web (waiting for reply)

Unfortunately, installing firefox did not do the trick.



I was unable to browse the web still from the previous firefox test, so I unregistered scrchpg.dll per your advice.
I tested firefox again, but couldn't browse the web.



I was optimistic that disabling the NDIS filter would correct the problem, but it unfortunately did not.
Should I re-enable the NDIS filter and re-register scrchpg.dll ?

Any other ideas?

Thanks,
Paul

We had an application on the non-working computers called Pearl Echo 6.0 Workstation (English) 6.06.0007.
Kaspersky technical support advised me to uninstall it. I uninstalled it and lost network connectivity.
I uninstalled Kaspersky AV but still had no network connectivity. I contacted Pearl Software and they
sent me an uninstallation tool. I ran the tool and my network connection was restored.
I reinstalled Kaspersky AV and so far so good. Kaspersky technical support was very helpful
in figuring out this problem.

Thanks for your help!
