Outlook 2007 losing connection to Exchange 2010 Server

I have an Exchange 2010 Server running on Server 2008 R2 with Exchange SP3 and rollup 1 installed.  Outlook users randomly loose connection to the Exchange server throughout the day even though all other network connectivity is fine.  This can happen to a user and the person next door has no problems at all.  It is happening to multiple users and there is no pattern as to when or whom it will affect.

Rollup 1 is very old, I would suggest an update.
Have you checked the network card drivers for the server are the latest?
Run BPA from within Exchange Management Console?

Although my instinct is that it is outside of Exchange. Do you get any errors on the server or the workstations at the time the error occurs?

Simon,

Thank you for the response.  I will check the NIC drivers to see if they are up-to-date.  Do you know where I can find the latest patches for Exchange 2010?

Microsoft Update will bring them down for you. Just run that and include any other updates it offers.

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

OK.  I've updated the NIC driver and Windows updates shows no updates needed for that server, including optional updates.  I'll have feedback by tomorrow if anything changes with the NIC driver.  BTW, the Best Practices Analyzer did mention that the network interface driver was "old".

BPA flags any drivers over two years old as "OLD". Doesn't always mean there is a more recent driver though.

To be clear - you ran MICROSOFT UPDATE, not WINDOWS Update? At the bottom of update screen it will say "get updates for Windows and other Microsoft products" (or something like that).

Thank you for the response.  I did as you mentioned above and there were some updates for Exchange including a Rollup 6 for SP3.  We'll see if these updates helped.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why
