Wrong OutlookAnywhere settings - 6.Jan.2011 7:49:02 AM

Hey all

I wanted to enable NTLM authentication on OutlookAnywhere, and after doing the command Set-OutlookAnywhere -IISAuthenticationMethods Basic,NTLM, my settings got changed. This is a dump before I run the command:

[PS] C:\Windows\system32>Get-OutlookAnywhere
ServerName : EXCAS01
SSLOffloading : False
ExternalHostname : exchange.asp.ssc.no
ClientAuthenticationMethod : Basic
IISAuthenticationMethods : {Basic}
MetabasePath : IIS://excas01.asp.ssc.no/W3SVC/1/ROOT/Rpc
Path : C:\Windows\System32\RpcProxy
Server : EXCAS01
AdminDisplayName :
ExchangeVersion : 0.1 (8.0.535.0)
Name : Rpc (Default Web Site)
DistinguishedName : CN=Rpc (Default Web Site),CN=HTTP,CN=Protocols,CN=
EXCAS01,CN=Servers,CN=Exchange Administrative Grou
p (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=Fi
rst Organization,CN=Microsoft Exchange,CN=Services
,CN=Configuration,DC=asp,DC=ssc,DC=no
Identity : EXCAS01\Rpc (Default Web Site)
Guid : 289b4865-caf1-4412-95ee-6fb0dff55e8b
ObjectCategory : asp.ssc.no/Configuration/Schema/ms-Exch-Rpc-Http-V
irtual-Directory
ObjectClass : {top, msExchVirtualDirectory, msExchRpcHttpVirtual
Directory}
WhenChanged : 05.01.2011 16:59:55
WhenCreated : 27.11.2009 11:20:12
OriginatingServer : asp-dc-1.asp.ssc.no
IsValid : True

Noticde the settings for "Name", "DistinguishedName", and "Identity". After I run the command, I ended up with this:

[PS] C:\Windows\system32>Get-OutlookAnywhere
ServerName : EXCAS01
SSLOffloading : False
ExternalHostname : exchange.asp.ssc.no
ClientAuthenticationMethod : Basic
IISAuthenticationMethods : {Basic, Ntlm}
MetabasePath : IIS://excas01.asp.ssc.no/W3SVC/1/ROOT/Rpc
Path : C:\Windows\System32\RpcProxy
Server : EXCAS01
AdminDisplayName :
ExchangeVersion : 0.1 (8.0.535.0)

Guid : 289b4865-caf1-4412-95ee-6fb0dff55e8b
ObjectCategory : asp.ssc.no/Configuration/Schema/ms-Exch-Rpc-Http-V
irtual-Directory

Directory}

WhenCreated : 27.11.2009 11:20:12
OriginatingServer : ASP-DC-2.asp.ssc.no
IsValid : True

Now, the "Name", "DistinguishedName" and "Identity" has changed, and when I try to change it back by running "Set-OutlookAnywhere -Identity "EXCAS01\Rpc (Default Web Site)", I get the following error:

[PS] C:\Windows\system32>Set-OutlookAnywhere -Identity "EXCAS01\Rpc (Default Web
 Site)"
Set-OutlookAnywhere : The operation could not be performed because object 'EXCA
S01\Rpc (Default Web Site)' could not be found on domain controller 'ASP-DC-2.a
sp.ssc.no'.

Remember, the RPC over HTTP works fine with Basic authentication (even with the wrong settings), but NTLM still doesnt work. How do I change back the settings?

Bit awkward to sa, but it looks like your website may have changed to EXCAS01\EXCAS01 rather than EXCAS01\rpc (default web site).
Have a look at your IIS config and see what it says.

I think you need to get back to your original settings before tinkering with getting your OA auth configured.

IIS looks good, nothing wrong there. And as I said in the previous post, Basic authentication works. Im thinking about disabling OutlookAnywhere, and enabling it again, but wondering if this may break my OutlookAnywhere Basic authentication. Does disabling and enabling it, revert the settings back to default?

Thanks for your answer Adrian

Best regards, Kent

I was posting about the last bit you wrote:

To suggest that you have renamed the sub site in IIS. On the basis this is not the case we can look at your Exchange config.
The config on IIS looks fine from an authentication perspective.
ClientAuthenticationMethod:Basic
IISAuthenticationMethods:{Basic,Ntlm}
This then suggest the issue lies in Outlook as we had to modify it to work in the way you are suggesting.
You need to check your Outlook accounts connection settings. Look for "Proxy Authentication settings" and make sure it is NTLM Authentication. We have it set via GPO so its is greyed out.

Disabled Outlook Anywhere from EMC, and then enabled it again after 15minuttes and a reboot, and now it works fine.
