I bought a PIX 515E on 8-2-06. The device has been performing fine, I am also running DHCP off this device.
Yesterday I had 2 PCs not able to access network or internet. It was discovered that they had a new subnet mask of 199.x.x.x vice 255.255.255.0. I did a release and renew and they started working again.
This morning, I have had 6 more PCs do the same thing with the same subnet mask of 199.x.x.x UNTIL a few minutes ago.
I just got a PC with a subnet mask of 120.120.120.120.
In each case, a release and renew solved the problem.
I only have one device handling my DHCP. Each time there was an issue the IPCONFIG /ALL showed that the DHCP server was the PIX 515E - which that is correct.
I am running Norton Antivirus Corporate Ed 10.0.1.1000 which handles spyware, etc.
Does anyone have a clue as to what is going on? Is my PIX 515E going bad, dropping packets, etc.?
Please help.
I'm very perplexed.
