I recently rebooted one of my exchange 2010 servers. I noticed a new user did not show up in the GAL. when I went to check it, I received an error stating the GAL could not be viewed and that the system attendant may not be started. When I checked the service it was not started but set to automatic. I thought it should always be running, especially when viewing the description of the service and considering it is set to automatic. This server generates the GAL. The system attendant on the other exchange server (in a DAG) is also not started.
My questions are:
Should I start it manually on both? Just the server that generates the address book? Will email be affected if it gets stuck starting?
Thanks for any help
