Dell dock/laptop issues

[shutupdonnie]

Laptop experiencing odd intermittent behavior w/docking station. Both laptop and dock are Dell. User was experiencing 5-15 minute wait after input of user credentials (users are on domain.) This is while laptop was docked. If user logged onto domain with laptop undocked, on wifi, normal login occurred. Laptop was re-imaged. User login performance is improved, but user now has to undock and redock to get some applications to work. Port replicator has also been replaced once. Port replicator pins and laptop pins appear undamaged. Any ideas?

If the dock is the type that has pins to physically connect to the laptop, I'd check to see if the connector on both the dock and the laptop are clean, not bent, making good contact, etc.

It sounds like you are zeroing-in on the dock being the problem. Do you happen to have another laptop that would mate with that dock?

I had a client with a WD15 Dell USB Type-C dock... never could get it working but we figured it may have been a bad dock as she got it on ebay.

It would mount, and unmount, and mount, and unmount incessantly... never giving Windows enough time to install... but would show up briefly in the Device Management

This is the PR03X dock. I've replaced at least one for this situation already. Laptop had the HDD replaced a few months ago. I don't recall the user having the issue before the HDD replacement. It could've been happening just not reported. I haven't checked event viewer/error codes so I need to do that.

This is the PR03X dock.

Getting one of those today. I have to admit I will rarely undock it though. I just wanted the extra ports.

I have an extended life battery so no need.

I would look into DNS issues.

My guess would be the laptop picks up a new IP when docked (as it switches from wifi to cabled). The domain controller isn't being updated to this DNS change which is causing authentication issues. The 5-15 minute wait is probably how long it's taking for DNS changes to be replicated over to the DC.

Or it's holding onto the wifi connection as well as the cabled connection? That could cause all sorts of issues. Try disconnecting wifi before docking.

will try the wifi disconnect ASAP
