"Please wait for the user profile service" on Exchange 2010 server

My server justed burped on me. i have 2 exchange 2010 servers in DAG setup running on w2k8 enterprise.

Since last night the my back up exhange server went crazy on me. the server databases on that box moved from healthy to failed. When i restarted the server to see if the database would go back to healthy state. the server gets stuck on "Please wait for the user profile service" when i log in using the domain administrator account. when i log into the server using local admin account the computer comes up to a blue screen and stays on there for 2-3 hrs and then finally logs on.

once logged on the Information store service will not start. it errors out with error code 2415. when i look at application logs it has event id 5000.

i  have tried articles that talk about reversing the order for the NIC cards, tried changing dependency services for MsexchangeIS but no luck.

any help will be appreciated!

Have you unbound IPv6? It will cause slow boot up and other issues with Exchange.
Just to clarify you need IPv6 to be bound or you'll have problems.
First change the binding order back to what it was.

Check the time on that server. Go into the cmd prompt and do "net time /set /y" and see if the server can time synch.

Then try a netdiag on it.

got it fixed guys!
I just rebooted the server once more logged in as domain admin. waited for like 30 minutes fo the message to go away.
Changed the dependency services for information store services.
Flushed DNS
added exchange server group to default domain controllers group policy

then it finally worked..
IT was the weirdest thing. One server was affected but the other wasn't.

Anyways its working now thanks for all your input.
