Applies to Kaspersky Anti-Virus 6.0 R2 for Windows Workstations v. 6.0.4.x

Description

“The specified network name is no longer available” error occurs on a computer running Kaspersky Anti-Virus for Windows Workstations version 6.0.4.x when locally accessing a shared folder by the DNS name (\\host_name\folder_name).


At the same time the folder can be accessed when addressed over the network or locally by IP address (\\host_IP_address\folder_name), by localhost (\\localhost\folder) or by the 127.0.0.1 IP address (\\127.0.0.1\folder).

Reason

This may be caused by a particular Anti-Hacker rule Windows "Server Message Block" Activity. When enabled, this rule blocks TCP connections on local port 445.

Solution

  1. Open Kaspersky Anti-Virus and click the Settings button;

  2. Select Anti-Hacker in the left panel and click Settings in the Firewall section;

  3. Go to the Rules for packet filtering tab;

  4. Disable the Windows "Server Message Block" Activity (TCP) rule by unchecking its box in the Action column;



  5. Click OK > Apply.
