The I.T. Nerve Center

Ever had a server that seems to run out of space only to find the the System Volume Information folder is using a TON of space?

Volume Shadow Copies were the problem in our case. Here is a link to explain exactly what Volume Shadow Copies are:

WCF Web Services, IIS, Kerberos, and Delegation problems are maddening!

Sometimes you implement something exactly as you have in the past, but due to some unforeseen circumstance it doesn't work as you expect. We've seen issues like this when implementing WCF web services on IIS 6.

Some things you can check are:

- Have you setup the proper service principal names for the service account running the application pool?
- Is the service account setup to run the application pool that is running the web service trusted for delegation?

Well we had an interesting problem this week. For some reason all of a sudden, users with Outlook 2010 started to have the application crash when they tried to open the application. Outlook would open fine in safe mode and if the user re-created their mail profile everything would work fine - until they rebooted.

After a reboot Outlook would again crash with an APPCRASH error with the culprit being olmapi32.dll.

It seems that radio buttons on forms displayed/rendered with SharePoint 2007 Infopath Forms Services are not working properly.

We have some internal custom forms on our SharePoint 2007 farm that are provided via InfoPath Forms Services. After I upgraded to the recently release Internet Explorer 9 Beta I could no longer select a radio button displayed on an InfoPath Form Services form.

Guess we'll need to file a bug on this one.

We use Citrix Netscalers for web application security and acceleration. In order to test some things before a deployment of some new Netscalers we wanted to test then using Citrix's Netscaler VPX virtual appliance (http://www.citrix.com/netscalerVPX).

It seems as if Google is dropping the ball with regard to true enterprise-level features in their Android operating system.

The Bottom Line: make sure your Exchange security solution/anti-virus is operating properly. Details below.

Here's an oddball issue we had this morning.
