NVBU Server is unable to connect to clients / clients cannot be added in client mgmt (4046018)

Date: May 2011
Product & Version: NetVault 8.5.3
OS Version: Windows 2008
Module & Version: 32 Bit
Application version: 32 Bit

Symptoms: Client can not be added after a new switch was installed.

The problem here was that Network packets, with the same source and destination ports were dropped. The DHCP was not resolving correctly either.

The issue here was a misconfigured switch.


The command “no dos-control l4port" on the switch was used to turn off the DOS-Control and now the it is possible to add the NetVault clients.
