Thanks for looking at my issue.
1st a quick layout of my office's.
I have a main office that houses our data center. DC's, excahnge, everything is there. We have many remote sites that are connected via a 92k FR DSL circuit. At each remote sites I have a cisco 1721 router connected to a managed netgear FSM726NA. I also have 1 Lenovo M52 PC at most of the remote sites. Several other type of PC's and laptops their as well. The IBM M52 are the main PC at the locations that multable people use. Those people all are differant types of user that have differant types of scripts and GPO's tied to them.
So the issue I'm having is this. The IBM pc is unable to find the domain controler when it boots up. Now I went through a ton of troubleshooting using netdiag and all that stuff and found everything to be clean. Just on an off chance I found that the netgear has spanning tree protocal enabled ( as most switches do by default). the clincher is that when the PC boots up the embedded NIC, an intel pro/1000 pm, reconizes that spanning tree is out on the network logs an event log. A clean one. Then the next event ID is one where the PC can't find a DC. So I disabled STP, rebooted and everything worked perfectly. After talking with some people who are more network wise then I am. They stated that STP was/is used to prevent looping broadcast between devices and if its turned off an mass packet strom could bring the network to its knees. So obviously this is something I want to keep enabled. I checked the NIC and the driver is up to date. All OS patches are up to date. I'm confused on where to go from here.
I called intel to see if this is an issue and they stated that this is an OEM NIC so I needed to call Lenovo... so no help there. I called Lenovo and they wanted to charge me 75$$ to look into the issue. Anyways, I'm stuck on where to go from here... experts please help!!!
Here is the event ID's from the event viewer.
