Excel files in use by 'another user' (user on Excel 2010)

I had a scenario where I had a remote user on a Wind 7 Pro SP 1 64 bit machine connecting to my SBS 2011 box and getting an error about Excel files being in use by 'another user.'  I turned off the auto-preview in Windows Explorer to no avail.  I looked through this page also to no avail:

The eventual solution was the registry entry change from the client machine described here:

SBS 2011 Backup Failure - A Volume Shadow Copy Service operation failed. Unknown error (0x800423f0)

I was configuring SBS backup on an SBS 2011 machine to a 2 TB external hard drive. But I got this error on the first backup:

SBS 2011 Backup Failures - A Volume Shadow Copy Service operation failed. Unknown error (0x800423f0)

After some quick research, I found that in some of the updates installed, there was a Sharepoint update that had downloaded, but needed to be manually installed. That's pretty lame, but whatever.

The method of updating Sharepoint properly is discussed here:

In essence, it's just go to an administrative command prompt. Go to this folder:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN

and run this command:

PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures

creating a CSR for a UCC SSL certificate on Exchange 2010 or SBS 2011

I installed an SBS 2011 box this weekend and I wanted to install a UCC SSL certificate on it. I get my certificates from godaddy, and this was the method I used in the Exchange Management Console to create the CSR that godaddy needed.

Here is the text in case that link ever gets moved or taken down:

Open the EMC

Select "Server Configuration" in the menu on the left, and then "New Exchange Certificate" from the actions menu on the right.

When prompted for a friendly name, enter a name by which you will remember this certificate in the future.

This name is not an integral part of your certificate request.

Under Domain Scope, you can check the box if you will be generating the CSR for a wildcard. Otherwise, just go to the next screen.

If you do select that box for a wildcard, skip to step 7.

In the Exchange Configuration menu, select the services which you plan on running securely, and enter the names through which you connect to those services, as prompted.

At the next screen, you will be able to review a list of the names which Exchange 2010 suggests you include in your certificate request. Review those names (using our SAN Name Help tool if necessary, and add any extra names at this point.

Your Organization should be the full legal name of your company.

Your Organization unit is your department within the organization.

If you do not have a state/province, enter the city information again.

Click "Browse" to save the CSR to your computer as a .req file, then Save, then Next, then New, and then Finish.

You should now be able to open the CSR as a notepad or wordpad file, and you will want to copy the entire body of that file into the online order process.
