outlook clients asking for credentials after server disconnection

hello,

i made a mistake somewhere on the IIs settings for my exchange settings and now everytime that the domain client losses connection to the exchange server, either be that the exchange server restarted, lost internet, client went to standby or whatever other reason that would cause a disconnection between either client or server, the client will ask credentials to the user when it tries to auto-reconnect to the exchange server, ad no matter what you put in on the credential window, it will not connect. the only way i can fix this is close the outlook and re-open it again and it connects fine without asking any credentials.

 it never did this before, it always auto-reconnected like nothing ever happend. how can i fix this? i know its a setting on the IIS because thats where i did the change and cant figure out what was it.

thanks for the help

If your unsure what settings been made you can always reset the vdirs on the cas server to out of the box.

rad, i would do that but then i would have to reset up all for the autodiscovery again. which is what i was trying to setup and i think caused the issue.  but the auto discover is working ok

xoom, rpc over http is setup. all clients, laptop/desktops get the settings from the server.  i noticed that they all have that enabled, regardless if they are internal or external.

did you try to remove it rpd over http and see if this is the problem ?

All you need to setup is the external URL and enable outlook anywhere, resetting the vdirs would end up being quicker.

xoom, i remove the entry from the clients, it gets added back automatically by the server.

rad, you mean setup the external url to fix the issue?

I would first check that all clients have the latest SP installed for them

2003 SP3

2007 SP2
http://www.microsoft.com/download/en/details.aspx?id=5

2010 SP1
http://support.microsoft.com/kb/2460049

If they are, it would be my guess that the issue isnt really isolated to Outlook.
But to other network connections or shared netwrok drives as well.

When you think about it, it kinda makes sense.

If a PC looses conenctivity to a newtork
and this PC has a shortcut on the desktop to a document on a netwrok share
when the connectivity returns, its not alway guranteed tht this shortcut is going to work.

If its a shortcut on a mapped network drive
One would be able to view their mapped network drives and see they are disconnected
The connection will not be refreshed until you manually click on them agian

Same with the shortcut on your desktop.

If yo uhave domain clients regurally looksing connections to the network or exchange server

I would make sure they are all on Cached Exchange mode untill netwrok issues are resolved.

Then i would get stuck into figuring out how to fix/repair the connection issue.

then you dont have to worry about closing outlook and re-opening

Are you sure you did not modify the Vdirs authentication methods ?
Like setting basic only, no authenticated, on some vdirs (autodiscover, webservices, oad... ?)

You know had you taken my advice and restored the virtual directories, this issue would probably be gone now.
