Network is completely useless

[Mike Chartre]

I have a dell precision m6300 notebook (Vista). It has been used on my
companys network with no big problems for six months. After a droped vpn
connection this weekend, the network is inaccessable through either nic or
wireless. VPN stills works (VPN passthrough to workstation). Internet still
works fine (wired or wireless). I can ping all network computers and vise
versa (router also). The laptop is visble by other computers on the
network, but not accessable. On the laptop, the network and sharing center
indicates all is well, but only shows the laptop and the router on the
network. File sharing and network discovery are on. I can even start
remote desktop sessions on the network. I cannot access any shares on any
computer. This also makes the syc center useless because the offline files
are stuck offline. I have reinstalled net adapter software to no avail. I
have tried a bunch of system restore points, but they never work. Tried
router firmware resets. All other network computers are working fine. Dell
tech support not able to help. I am out of ideas.

Any help would be greatly appreciated.

Thanks,
