slow local move of exchange mailbox on esx
This week I ran into an annoying issue during a migration from exchange 2003 to 2010. The local move of mailboxes was taking too long. It took about 20 minutes to move an almost empty mailbox.
I decided to test how fast a file transfer went from the old exchange server to the new one. Even whilst browsing the folders on the old server I noticed that it took too long for the folder content to be shown.
The new server was running as a guest on an ESXi server. VMXnet3 was used as a network adapter for this server. I decided to disable all offloading in the driver configuration. Next to disabling it in the driver settings I turned off autotuning and RSS.
netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled
After these changes the server was rebooted. Once the reboot was completed speeds were back to normal and I could continue moving mailboxes from the old to the new server.
Connecting Storage Server Essentials to a domain
When you try to connect an Essentials Storage Server to a domain you might run into the following issue:
As you can see the ‘Change’ button is disabled. This behaviour is normal. To connect the server to a domain you need to use the dashboard application.
When you click on ‘Server Settings’ a new window will pop up.
On the domain tab you can fill in the domain name. Once you clicked the ‘join domain’ button you will need to supply the credentials of the domain administrator.
After connection you can select the security group that will be displayed in the users tab of the dashboard.
When the process is completed the server will need a reboot. After the reboot you can see the users from the group in the dashboard. If desired you can change this group under the ‘domain’ tab of the ‘server settings’.
