Have 10-12 XP pro pcs on a lan with dhcp from a pix501. I have two machines that lose internet access, but the others dont. It appears to happen randomly, and then they just start working. When it happens they can still access shares on other pcs and server apps, just no internet access.Reboots dont fix,disabling the nic and renabling does not work as well. The other pc's do not have any problems. Have checked for spyware,virus, etc.. machines ( Dell 3000's) seem clean and do work well. Any ideas would be helpful. Thank you!
Do you only have a 10 user license on the PIX? If so, this would make sense. Do a "sh ver" and it will tell you. You will only be allowed 10 outbound connections. You can also test this by shutting down two other systems, and see if the others work.
