Friday Tip #3 – DNS/Spamcheck

  This is the third Friday tip and maybe the best of them all J To have a complete check on the customers external DNS when doing a mail project is maybe the best thing to do. Very often I see that “everything” looks OK but when checking for PTR records they doesn’t exists.

Databases doesn’t show up

  This error came up to me after installing an Exchange 2010 CAS/HUB server and a Mailbox server. The server doesn’t show any databases; by default the server itself creates an “example” database like Mailbox Database 4385492. But it didn’t show up! After running ExBPA I found out that the ‘homeMDB’ value for System Attendant service was missing. This caused the error. By following this article on technet the error went away: http://technet.microsoft.com/en-us/library/dd535374(EXCHG.80).aspx In addition to what I wrote earlier in the post, I’ll update it here with a picture…

Recover failed Exchange 2007/2010 server installation

A time ago I had a little problem with an Exchange 2007 (SP1) installation. The server I was using was prepared with Windows 2008 R2 Standard and I was told that this should be supported if Exchange 2007 is using SP2. Well, with that said I could install Exchange 2007 including SP1 if I used Compatibility mode. But when I should update it to SP2 it wouldn’t run the installation even if I used the Compatibility mode. The only option that was available for me was to uninstall Exchange 2007,…

Creating a D.A.G (Database Availability Group)

  A little introduction The HA functions in Exchange have been changed a little bit; LCR, CCR, SCC and SCR are now away and replaced by D.A.G. I think it’s a very cool and great feature with Exchange 2010, maybe the best J it makes it able to create a copy of the database to a different server(s). You are able to have more than one copy of it, so your server1 holds an active copy of DB1, server2 and server3 can hold this database as passive if server1 is…

Restore single user mailbox content using Exchange 2010 and DPM 2010 Beta

  Prerequisites An RDB must be created. The database and log files containing the recovered data must be restored or copied into the RDB folder structure that was created when the RDB was created. The database must be in a clean shutdown state. Because an RDB is an alternate restore location for all databases, all restored databases will be in a dirty shutdown state. You can use Eseutil /R to put the database in a clean shutdown state. (Text copied from technet) Step 1 Start up DPM 2010 and go…
