Network Problem
LockedHi,
All of the sudden our internet connection is acting weird, it tends to phase in and out. For a couple of minutes certain sites we cannot get to (microsoft, hotmail, symantec, etc…) and other sites works fine. And then everything starts working again, we can access all websites but this doesn’t last very long. It takes about 30 sec to a minute then it starts to not work again. And in about 3-5 it comes back. This happens to all stations and server within our network.
We have a T-1 line that connected to a cisco 1700 router. We also have a sonicwall pro 300 for our firewall. I’ve checked everything and all seem to be normal. This seems like a dns issue but I tried using both internal and external dns and still getting the same problem. I’m kinda new to this so can someone point me in the right direction and tell me what check for so I can resolve this very weird issue. Thanks in advance.
