New Exchange 2010 server lag issue
Posted on 2015-01-09
I have Exchange 2010, running on Windows 2008 domain controller. I added a new windows 2008 server to my network to replace the domain controller. I installed Exchange 2010 on the new server (with the old server still on the network). Everything replicated, I moved mailboxes, and all seemed good. I temporarily powered down the old server to make sure that everything was installed and configured correctly on the new server. **I have not done dc promo yet on old nor have I uninstalled Exchange - this is going to happen when schedule permits)** In the meantime, new server is running smooth EXCEPT - when users are in Outlook, they click on new email or reply to an email and outlook sits and "thinks" for 30-60 seconds. Its very annoying to users and with good reason. I believe that Exchange is looking for the first database (they are both still listed in my Exchange management console since I have not uninstalled the old one yet) and basically waiting for a timeout or something before going to the current database.
How can I quickly resolve this lag until I actually uninstall exchange from the old server? I was trying to find information on maybe making the new database primary or changing the timeout or something but am not having any luck.
Thanks for any suggestions.
