We have about a dozen computers at an office on Verizon DSL. They are behind a Sonic Wall TZ170 router, and a Dell switch (I think). All of the computers except for 2 can route fine. These 2 computers can only route to GMail and Google. They can do searches in Google, but can only click on the cached pages. They time out when trying to access e-mail from Outlook.
First computer is a Dell Optiplex (forgot model). It was working fine a week ago. No patches or changes have been made on this computer, or the network. It runs XP Pro.
Second computer is my laptop, running XP Pro and Ubuntu 64 -- it works absolutely fine at home.
Here's my notes:
- No proxy being used
- Cleared ARP
- Rebooted router, modem
- Hooked straight up to modem -- the Dell and the laptop work fine then.
- Assigned IP addresses (no change)
- ICMP passes through fine
- Checked Sonic Wall -- no changes have been made, rules look fine. Opened it up to all traffic, still can't route right on those 2 computers.
- Ran a sniffer, saw nothing unusual.
- Ran anti-virus scans and anti-spyware using CA eTrust, Pest Patrol, and Zone Alarm anti-virus. Also used Panda and the free scan from Trend. Nothing found.
- Same DNS as other computers.
Any suggestions? I don't understand what in the Sonic Wall is stopping these 2 computers. We have no filters setup or special rules for any of the workstations on the network. I looked at every single option on the Sonic Wall, and verified it against what I had in my notes (we record our settings on paper) and they are absolutely fine. I'm literally out of ideas, short of replacing the darn thing.
