Laptop won't allow domain login while on network

Here is the scenario.
1. We plug laptop into the docking station and it will not come up on the network.   Cannot login to domain.  Note  it is not the docking station  network is active.
2. Then we disconnect the cable, login locally to the laptop and plug the network cable back in.  Laptop comes back up on the network.
3. Can do same as #2 but using wireless.  Meaning login locally to the laptop, connect through wireless and then we are on the network.

How are you entering your username and password when trying to logon to the domain ?
it should be domainname\username and then your password
Also, are you on a static ip address or dynamic ?

We did resolve this but it's been so long I don't remember the details.  I'd like to just close this out as I don't feel the information will be useful to anyone

the problem most likely is that your computer was no longer active in AD.  you would have had to remove the computer from the domain, change the SID, and then rejoin so AD sees it as a new computer.  the reason why you can log on locally is because it doesnt talk to a DC to authenticate.  the reaosn you can log on when the cable is unplugged is because your logon in cached in windows and its using the cached info to authenticate.
im posting this for others hoping the info helps them.
