Hi,

we use a sbs2011 with exchange 2010. Everything worked fine till some days ago. All users are not able to use the "automatic replies" (out of office assistent). It says that the server isn´t there. Outlook still works fine. So i tried to access the webaccess. From the server i can access owa with https://ip/owa , https://servername/owa and https://localhost/owa.
From Internet it works to with https://dyndns/owa.
But from every client in LAN (XP and Win7) i get the "The page could not be shown"-message in the browser.

Any ideas ?

Thanks in advance

There are two possible causes for this, first check out:

If that isn't the problem, then there is something wrong with your autodiscover service which is usually caused by incorrect DNS settings or an improperly named SSL cert.  However, I'm assuming that it's the .NET issue because you aren't experiencing the problem universally.

Do a nslookup on the clients to check if the "servername" or "domainname" gets resolved correctly. If not, you can add an A record in your DNS to fix it.

It can't be that, because it resolves from the server.  It very well could be erroneous DNS entries on the workstations.  They should ONLY have the SBS's IP as their DNS Server.  No other DNS Server IPs should be listed on them.

Also, on an SBS its best to not enter manual DNS entries if you can avoid it.  Better to run the "Fix My Network" wizard which will ensure that ALL settings are correct in ALL places.
