We've had an ongoing ordeal with a laptop for going on three months now and have tried just about everything to resolve it. We have had this problem with two seperate Dell laptops--one a Latitude X300 and another a Latitude D620. We haven't had this problem with any desktop machines or laptops that aren't part of a domain. The problem in a nutshell is this. When the laptop is part of the domain it will hang during logoff for about 10 minutes before finally successfully logging off.
At first glance you may think "easy, it's a GPO logoff script problem which times out after 10 minutes". The problem is we don't HAVE any logoff scripts (or shutdown scripts for that matter). And just to make sure it isn't a GPO causing the problem we put the machine in an OU with no GPO's and set the OU to block all inheritance of GPO's above it. We've confirmed that there are no GPO's being appiled by running "gpresult" from the command line. We've also tried only applying a GPO that applies the policy to set a maximum time for Group Policy scripts to 30 seconds. None of this has worked.
Here are a list of 19 other things we've tried without success.
1—Installing and Uninstalling both versions of Office (2003 and 2007)
2—Uninstalling Symantec Anti-Virus Corporate Edition 10
3—Uninstalling Blackberry Desktop
4—Disabled Smart Card
5—Disabled Wireless Card
6—Reinstalling video drivers
7—Blocking all group policies
8—Unplugging laptop from network before logging off
9—Running Dell hardware scan
10—Wiped computer and completely reinstalled operating system
11—BIOS is the latest
12—Turned off NIC PXE boot
13—Disabled internal modem
14—Virus Scan w/latest defs
15—Anti-spyware scan w/Defender
16—Uninstalled Windows Defender
17—Wrote time out script for logoff scripts through GPO which times out at 30 seconds
18—Tried User Profile Hive Cleanup Service
19—Tried logging on with domain user with and without admin access
Numbers 2, 7, 8 were the result of searches on Experts Exchange for people with a similiar hanging logoff problem. They obviously didn't work in our case. So what is the similarity between these laptops and the rest of the machines we've worked with? Simply that they both have wireless cards (as well as internal network cards). However you would think that if this were the case DISABLING the wireless card would fix the problem, but it doesn't. You might also be tempted to advise us to call up Dell support. However I KNOW when we tell Dell that this has happened with two seperate laptops which are also different models they are going to tell us it's a software problem (and consequently not help us at all).
As as absolute LAST RESORT we will simply have to give our boss (yes it's our BOSSES laptop! ) a laptop that isn't part of the domain. However we would rather not have to resort to this, since we then won't be able to apply GPO's for security, she'll have to login to her Outlook manually (when you're in the domain it gets the credentials automatically from your domain login), and she'll have to launch a VPN connection to get to our server. I simply can't believe that no one else in the world is having this problem, or that Windows just naturally has problems with this. Any help is MUCH appreciated. Thanks!
