Notebook with high CPU usage when connected to domain network

I have a client with notebook with Windows 7 installed. This notebook is part of a Server 2012 domain. He is primarily in a sataliite office that's connected to domain over VPN. His notebook was working fine. Until a couple day ago when he was at the main office and attempted to log into his user account while on the local network. He was presented with the login prompt, but then it just showed the spinning graphic and never completed login. Back at this sataliite office it now was doing the same thing.

I picked up his notebook. Brought it back to our office, on different network of course. I was able to log right into notebook with both his domain account and the local administrator account. I've reviewed the event log files and the only error was related to Component Services permissions. I ran both chkdsk and sfc on drive. No errors.

I returned the notebook to clients office. It started to do the same thing again. I was able to get it to login under local administrator account and run ProcMon. I filtered down to just the process (svchost) that was using all the CPU resources. In procMon I could see that it was accessing writing & closing the edb.log file continusly.

I've now have the notebook back my office and it's working fine on my network. Any thoughts?

Thanks, Lee

It sounds like you have a VPN issue. If it works in your office but not the other take another known good PC there and try to log into the network. See if you can ping your domain controller. Look at any firewall issues that might be blocking ports needed by domain controller.

Look for any rogue WiFi devices that might be conflicting with your network hardware.

I think the local profile has gone corrupt....Rename the account and in the registry.

Reboot and then inform the user to login...wait for 10 minutes.

Can you login as another user? That will test a profile issue.

Rsayer: There are other computers on this VPN/Domain that are not having any issues.

Deb9 & Rsayer: Even when I login with the notebooks local administrator account I have the same proble. So I don't think it's the domain users profile.

Could it be the computers domain profile that's corrupted?

Thanks, Lee

On that same notebook can you log in as the domain administrator? What if you unjoin from the domain then rejoin?

If you are not able to login as admin then it looks like a dns issue.

Login from another network. Make changes in dns and then check.

Can try this hotfix

Just wanted to post an update. Nothing we've tried have corrected the issue we're having on this notebook. Right we're waiting for the client to decide if they're willing to spend the money to restore with factory restore disk. Or just purchase a new notebook since it 3-4 years old.

Have to do clean install to find out whether its a hardware or user profile related.

After doing a clean install give the notebook to another user or you can login with your credentials. You need to monitor this system for 2 days with your id and do not allow anyone else to login.

If this works then the problem is with the server user profile  and not the system.

In the end we discovered the issue was with a corrupt ATT Connection Manager installation. Once it was uninstalled the notebook was able to connect to the domain. The Connection Manager was used for the Broadband USB Stick. I wasn't looking at it as the cause of the problem because it had been installed on the notebook since the beginning. Why it would connect to my network and not the clients own network is a mystery for another day.

Thanks for your assistance.

Althought the solutions provided by the members were good ideas. They were not the solution. But I also hadn't provide a key piece of information (ATT Card) to them to properly solve the problem either.
