Thinkpad wireless connection problems

My Sr. Pastor has a Thinkpad X41 tablet that has recently developed wireless connection issues when connecting to a WPA secured network. He has no problems connecting to open free networks such as our guest network and the networks at places such as Panera's etc. I have tried just about everything that I can think of trying and was wondering if anyone has experienced similar problems. We are primarily a Dell shop so most of my experience is with their laptops but the other Thinkpads we have are not having any problems. I have updated the driver, tried a rollback system restore to a time when he had no problems connecting, I even reinstalled the network drivers. The secured wireless network is identified and it says it is connected but it never does authenticate and issue an IP address.

Any ideas about what else to try to fix this problem?

Thanks!

Mailbox storage quota???

Just curious....would anyone want to share what size limits they place on their users' Exchange mailboxes? We have not had quotas before but are needing to implement them next week. We have a couple people with nearly 1.5 GB of stuff in their mailboxes. Just wondering?????

Cool Tool found

Don't know if any of you have found ManageEngine's ADManagerPlus but we recently discovered it and it looks like it is going to be a very useful tool for us. In a very easy to use GUI, you can view and edit your Active Directory and pull some very helpful reports such as Passwords soon to expire, inactive computers, recently modified computers, etc. You can even create and modify the users and their attributes within AD. There is a free version and a paid version but right now we are just playing around with the free version because, it's free, and it appears to have all the functionality we need at this time.

I would love to hear if anyone else has any knowledge or experience with this product whether good or bad.
