File not found error uploading multiple files to SharePoint

A colleague of mine recently had an odd issue when trying to uploading files to a SharePoint site. Here’s what happened…

When he tried to upload multiple document to a MOSS 2007 document library from a Vista desktop that has IE8, things worked fine if he was using documents that are in his user profile. But when he selected documents that were not in his user profile (Ex: folder on c: drive or USB drive), he got a file not found message when trying to upload.  If he upload a single file from the same location, or if he dragged and dropped via the explorer view he have no issue.

I hadn’t seen that particular issue before, but I have seen weird behavior with Vista about accessing certain files when UAC is enabled. Basically, Vista wants to raise the UAC dialog box to allow you to access files off of root drive directories, including USB drives. But, I thought I remembered that Vista sometimes cannot or does not display the UAC from Internet Explorer. So IE just fails if it needs to access these files.

I recommended that he disable UAC on his Vista machine as an easy way to test. Good news: it worked. The moral of the story: if Internet Explorer is behaving oddly when needing to access certain files on a Vista machine, try disabling UAC.

Microsoft’s Tim Sneath has a how-to on disabling Vista UAC.

Bluetooth not working after Vista resume from sleep

I’ve had a problem with my Bluetooth on my Vista x64 laptop ever since I got it. Everything would work fine when the laptop first booted. However, when I suspended the laptop and subsequently resumed, non of my Bluetooth devices could connect to it. I was stumped. I tried updating my Bluetooth drivers, Windows patches and service packs. I’ve had the problem since RTM, with service pack 1 (SP1) applied, and the problem is still there with service pack 2 (SP2) applied.

I’ve seen a lot of people having similar issues. Unfortunately, all I can contribute is a workaround. That said, the workaround has worked well enough for me, but only because I do not typically need by Bluetooth devices all of the time. You’ll see when I mean soon.

The workaround is simple: after I resume the laptop from a suspended state, I disable and re-enable the Microsoft Bluetooth Enumerator driver in the Vista Device Manager. The process takes about 1-2 minutes, so it would be quite a nucense to have to do it every time I resumed my laptop.

Here are detailed instructions on how to disable and re-enable the Microsoft Bluetooth Enumerator driver:

1. Click on the Vista Start button
2. Right click Computer
3. Select Manage
4. Select Continue on the User Access Control (UAC) dialog box
5. Select the Device Manager node from the tree view on the left
6. Expand the Bluetooth Radios node from the devices tree node on the right
7. Right click Microsoft Bluetooth Enumerator
8. Select Disable
9. Select Yes on the confirmation dialog box
10. Wait for the device to be disabled
11. Right click Microsoft Bluetooth Enumerator
12. Select Enable

You should now be able to connect your Bluetooth devices to you Vista computer.

You can see this is quite an annoying process, but it has worked fairly consistently for me. I have Vista x64 Business Edition running on an HP Compaq 8710w Mobile Workstation with a Broadcom Bluetooth driver.
