Hello,
I have an odd situation where we are preparing 2 exchange 2013 servers to migrate 2010 servers to
so currently:
2x Exchange 2010 (with dag)
2x Exchange 2013 (with dag).
Now it's behaving extremely odd when it comes to ECP for the 2013 servers.
randomly it works and doesn't work.
i generally try it from localhost on both 2013 servers, and individual server ip's from lets say 4 or 5 places.
all same login, and admin user is inside mailbox db DAG cluster.
now the problem:
it randomly pops up auth.owa error 500
when i say random i truly mean random, sometimes everything 100% works, i am able to login 100% from all servers.
then i check back lets say 2 hours later.. some obtain auth.owa errors while others work.
What i tried:
- I rebuild OWA (first with reset, then with remove and re-add method) on both 2013 servers.
- removed killbit file from 2013's
- rebuild exchange 2013's (just exchange it self).
- checked heartbeat monitor boxes and removed the null values.
----------------------------------
It's safe to say i am kind of lost on what to try next.
i am also mistefied why it randomly works, i know it's internally loadbalanced, but shutting down 1 of the 2013 servers did not get rid of this strange behavior.
is it possible that the exchange 2010 servers play a part in this issue?
Any ideas, any help is very much welcome!.
Regards,
Marco
