MS 4.0 Losing Connection?

We upgraded from CRM 3.0 to 4.0. If I start MS Outlook 2007, it connects to
the CRM server just fine. In the task bar there is a MS CRM icon. After a
couple minutes, I get an error message popup from the MS CRM icon that says:

"Unable to Connect. Lost Connection to Microsoft Dynamics CRM. Microsoft
Dynamics CRM will restore the connection when possible. To stop retrying,
right-click and select Sign Out"

However, in my Outlook client, I can access the CRM info with no problem.
The "Unable to Connect" message keeps popping up until I right click on the
icon and click "Exit".

1. Any idea what the icon service is doing?
2. Any idea what I can look at to see why it is "disconnecting"?

Try running the diagnostic tool to see if there are any problems.

I ran the diagnostics and received the following error:

tests that require connectivity will not be run. Verify the specified Web
service address and check for connectivity. If necessary, rerun the CRM
Configuration Wizard. ---> System.Net.WebException: The remote server
returned an error: (401) Unauthorized.

If I manually go to this address, it opens just fine. Also, it connects
fine in Outlook and never loses connectivity. However, the "service" running
in the task bar keeps popping up with the error that it has "lost
connection". I tried changing the server name to the actual IP address, but
receive the same error in diagnostics. Any ideas?

By chance did you figure this out? I'm having the exact same problem.

Did you ever resolve this issue? We've just started seeing this problem
with our Outlook connection also...

We are also seeing the same problem, on both upgraded and clean new
installs of the CRM 4.0 client. Everything works, but there's an
annoying popup.

I think it might have something to do with the "friendly name"
resolution. Looking at the registry, I can see that some of the urls
reported by autodiscovery are in the form:


That address does not work in a browser, but


works fine.

I manually changed the registry values to be:


and diagnostics still says that address is not responding, even though
the client is working fine, and you can use the browser interface at
that address as well.

I have the same problem as well. What is worse is when it happens on my
laptop (offline outlook) it CRASHES my outlook. I too have tried to edit the
ServerURL registry setting with no luck. There must be a bug somewhere.

Seth -

I was having a similar problem. Turns out I had made a password change that
had not propagated across the network. I had to push it out onto each
machine and that fixed it for me.

Control Panel -->User Accounts (highlight desired user
acct.)-->Advanced(tab)-->Manage Passwords(button)...opens 'Stored User Names
and Passwords' dialog.

Select each one, click the Properties button, and enter the proper password.
Repeat for each entry.

This solved it for me, but there is always a chance that it won't do it for
you. Good Luck!

Was able to solve the issue. Go to IIS > Microsoft Dynamics CRM > _imgs.
Right-click the _imgs folder and click Properties > Directory Security.
Under Authenticate and access control click Edit and ensure Enable anonymous
access is checked. Previously with 3.0 this was not checked, but it needs to
be checked for 4.0.

Thanks for the help.

This has help me solve the major issue of 'Lost Connection' which in turn
allowed my laptop client to function without continuous crashes.

Since the change I now have a new issue with my terminal server outlook
client always prompting me to start in SAFE MODE. I tried to fix/repair which
did not help. I also tried to create a new profile, but all with no

also, I had to DISABLE synronizing outlook contacts as suggested by MS as
per a documented bug to prevent my laptop crashes when syncronizing.

"...launch Outlook with CRM toolbar enabled. Go to CRM tab then OPTIONS then
go under SYNCHRONIZATIONS and uncheck CONTACT then close the Outlook and
launch again"

Great work and special kudos @VGroupby1. I am always curious how you guys
find these things out. Gotta have something to do with VS and undo disks +
mega free time. l:)
