Dialogic DMG VoIP Gateway Drops Lync Calls Placed on Hold

We are implementing a pilot of Microsoft Lync 2010 and we've been running in to a few little quirks.

We are using a Dialogic DMG VoIP gateway to interface with our legacy telephony equipment to receive calls from the PSTN.

Here is the current quirk that was encountered: any call that originated from the PSTN to a Lync user that was placed on hold would disconnect after exactly 90 seconds. The following information was observed in a Lync trace of the call:

Getting prompted for credentials when trying to add a reference to a WCF web service in Visual Studio

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.

- Is the service account setup to run the application pool that is running the web service trusted for delegation?

Outlook 2010 olmapi32 App Crash - Check out Safe Senders List GPO

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.

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.

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

Deploying a Window Server 2008 R2 VMware Template and Joining It To A Domain

Have you been pulling your hair out trying to get a Windows Server 2008 R2 virtual machine deployed from a vCenter template to join a Windows Active Directory domain? Fear not, the solution is at hand and is realtively simple.

After reading the following thread on the VMware Communities site:

I found out that one needs to use the FQDN of the AD domain and NOT the NetBIOS name of the domain, and also the user principal name for a user with proper permissions to join computers to the domain.

Samba 3.4 on CentOS 5 - RPMs available - Resolve winbind issues with Windows Server 2008 R2

A friend of mine uses Samba and winbind on his CentOS Linux boxes for user and group information and Kerberos for authentication. He upgraded his domain controllers recently to Windows Server 2008 R2 and suddenly his winbind authentication broke.
