What to do when the Transaction Log LUN is full?

Hi everyone, I think most of us have or will run into this problem some day or another 🙂 With that said, I hope this post will help others that will hit into the same issue. A time ago I was heading into this issue when doing a large migration. We were using a 2 node DAG with normal logging enabled. Anyway, after some hours the LUN was so full that the databases were dismounted. I didn’t monitor the disks but I noticed that something was wrong with the system…

What about Legacy / Coexistence for OWA?

  Hi After reading and answering in MS forum I can tell you all that this is a very common question that need to be clarified. Before Exchange 2010 was released there was a built-in function that handled the co-existence for OWA. A little background check, Exchange 2003 and 2007 could co-existence by pointing to the Exchange 2007 CAS server(s) and use /exchange. In Exchange 2010 this function is removed and replaced by “Legacy”. What to think about when you are planning for a co-existence? You need to add the…

OWA/ActiveSync with Exchange 2007 coexist with Exchange 2003

  In this scenario when have a single Exchange 2003 standard server installed and installed a new server with Exchange 2007 standard with CAS/HUB/MBX role (multi-role server). Our problem was that we had too many users that used OWA and ActiveSync so we couldn’t be without this function. I this case we had 3 different solutions to choose between. 1. Use two different IP addresses; one for the Exchange 2003 OWA/AS and one for the Exchange 2007 OWA/AS 2. Use a front-end firewall like ISA server or something else to…

For a couple of months ago i had a really hard problem while demoting an old Exchange 2003 after a transition to Exchange 2007.

But found a solution well hidden on a forum and I want to share it with you J it’s kind of copy and paste on this. Open adsiedit.msc Select…
