Limited or no Connectivity through LAN (Ethernet)
Posted on 2009-04-17
A clients computer is unable to access the internet at all. When I first went and saw them, I found that their modem had a dodgy power button and any slight movement would turn the modem off. 1 new modem later and the problem still remains.
After checking the usual - IE settings, LAN settings - I determined that it must be a faulty onboard NIC. 1 new NIC card later and the problem remains. I took the machine home.
I have a wireless Desktop with ICS set up through its nic to my 'test' PC and a wireless laptop successfully accessing the net with my Belkin Modem router. 1 Vista, the rest XP pro. So my Router is a happy camper.
I wired the clients PC directly to the router through ethernet (they have XP home) on both the new card and the onboard and get "Limited Or No Connectivity" bubble appear.
**WHAT I HAVE TRIED**
= Checked IE settings: Never dial up, obtain automatically, no proxy, no dialup accounts left behind
= Local Area Connection is set to obtain automatically. Tried to set a static IP with the same settings as my test pc (using that machines PSU as that is broken on clients machine too) with the same result.
= Tried firefox (clutching at straws, but you never know). Same deal.
= Found a remnant folder of CA eTrust security suite in the program folders. This had obviously not been uninstalled correctly\fully. *feigns shock* Found a previous post on here relating to this and removed all reg entries and folders. Nothing checked in startup menu. (This is my biggest suspicion of the culprit)
= Drivers are fine. (brand new PCI nic card remember?)
= I have reset the TCP\IP through cmd (netsh ip reset) and also gone into the local area connection and reinstalled through there.
= Ethernet cable works fine with other machines so it is not a faulty cable.
= Rebooted my router for good measure
They tell me it just "stopped working a couple of months ago." I have tried my laptop on their connection just to test it out and it works fine. If I had to guess I would say that the CA firewall remnant (it was in the startup list) laid dormant until SP3 came along and played its screwy game on it.
I am at a total loss and am tearing my hair out! Any help is greatly appreciated. I am really really trying to avoid a reinstall and just really really wanna go play with my new laptop I got today!
