I was recently attempting to upgrading my Symantec antivirus clients and received an error. According to the Symantec Knowledge Base (see link below), the problem is often rooted in DNS. I beleive this to be the case since I can no longer ping any client computers within my network either by HostName or IP address. Everything on my network seems to be working fine which has got be perplexed.
When I Ping HostName, I get the following...
Pinging HostName.DomainName.Com [192.168.1.12]...Request time out.
When I Ping 192.168.1.12, I get Request time out.
According to my domain controller, DNS, the HostName and address are correct in the forward and reverse lookp zones. The client computer is ON, firewall diabled, and it is indeed 192.168.1.12. Clients are XP Pro, Servers are SB2003. Symantec is 10.2.
I am not an expert with DNS so any help is appreciated.
Here is the Syamntec page I mentioned.
