How do I remove "InternalNLBBypassUrl : https://anydomain/EWS/Exchange.asmx" in exchange 2010

Get-WebServicesVirtualDirectory | Set-WebServicesVirtualDirectory -InternalNLBBypassUrl $null

You should not modify this value

I was wondering why the contractor removed this value last week when he worked on it. Endital1097 - why shouldn't the value be modified? The emc is now giving me the below - any suggests?

WARNING: IIS://server.domain/W3SVC/1/ROOT/EWS wasn't found. Please make sure you've typed it correctly.

unless you have an NLB InternalNLBBypassUrl is not used. you asked how to remove it and I told you how.


This being said it is by default the FQDN of the CAS server and this is exactly how it should be.

Your EMC error looks like the whole ews virtual directory was deleted

run Get-WebServicesVirtualDirectory what is the reply ?

Your right - I just wanted to know why endital post that comment. I get the below reply

Name                                    Server                                  InternalUrl
----                                    ------                                  -----------
EWS (Default Web Site)                  EXCH-HUB-01                         https://email.corp.domain.org/ews/e...

When I run you command I get the below reply:

Yes, someone deleted the EWS directory and it won't let me recreate it . . . Any ideas

ok open IIS default web site and check do you have an ews virtual directory there ?

please share a screen shot

There are some EWS calls that cannot fall back to another CAS and these must be proxied to the CAS or the request fails. These requests use the InternalNlbBypassUrl

If a CAS server is behind an NLB this value should not be changed, and just as a best practice should not be changed at any time

Ok . . . Here is the screenshot your requested. ews-image.doc

please try to post the pics as JPG next time, it takes much less time to dowload :)

it looks like the ews is showing but something is still wrong

pleaase run

Get-WebServicesVirtualDirectory | remove-WebServicesVirtualDirectory

New-WebServicesVirtualDirectory -WebSiteName "Default Web Site" -internalURL "https://email.corp.domain.org/ews/Exchange.asmx"
what are the results

Here are the results - the EWS directory is still showing.

The Web site 'EWS (Default Web Site)' on server 'EXCH-HUB-01.corp.domin.org' doesn't exist. Web site names are case sensitive. Parameter name: WebSiteName + CategoryInfo: InvalidArgument: (EXCH-HUB-01\EWS:ADObjectId) [New-WebServicesVirtualDirectory], ArgumentException + FullyQualifiedErrorId :7707297B,Microsoft.Exchange.Management.SystemConfigurationTasks.NewWebServicesVirtualDirectory

this result is when you did what ? the first or the second command ?


run the below again please


Get-WebServicesVirtualDirectory | remove-WebServicesVirtualDirectory

if
Get-WebServicesVirtualDirectory | remove-WebServicesVirtualDirectory

ran without issues please run after

Get-WebServicesVirtualDirectory

are you still getting

"WARNING: IIS://server.domain/W3SVC/1/ROOT/EWS wasn't found. Please make sure you've typed it correctly.

if not kindly run

New-WebServicesVirtualDirectory -internalURL "https://email.corp.domain.org/ews/Exchange.asmx"

Sorry - Here you go.

the second command is


New-WebServicesVirtualDirectory -WebSiteName "Default Web Site" -internalURL "https://email.corp.domain.org/ews/Exchange.asmx"


there is no EWS before default web site name

Your right . . . that would make it fail - not to mention I didn't remove the brackets either (lol) . . . I just made me so oatmeal.

Already on it for you . . . Here is what I've done - no errors except for the "can't resolve" (what is your thought on this)
Also, since we have NLB configured in the environment - do I need to remove the InternalNLBBypassUrl?

all is well,

for the cannot resolve part is simply because the url you put in the external URL is not resolvable by your server, you can ignore it.


And no do not touch the InternalNLBBypassUrl

You are fully working again

Ok . . . I just tested access to EWS - I thought I was suppose to get an XML  file popup ??

run iisreset and try again

Running iisreset /noforce . . . Also, since we have to CAS/HUB servers - should the other one have the  same setup in IIS in regards to vitural directory?

I dont understand you have 2 cas servers?

Yes, I have two servers with the Hub Transport, Client Access roles installed. I've ran iisreset and here are the results (different error message) . When I look at the other server it's not showing the EWS folder either . . . I was out on vacation and came back to a mess. Exchange is new to the environment and me.

Please run new-webservicesvirtualdirectory on the other server as well,

Please try rebooting your cas

Rebboted boot cas/hub server . . . was able to create the virtual directory without fail - see screenshot   Still getting the  

Ok . . . I worked it out.
The problem  MSExchangeServicesAppPool not started in IIS
THANK YOU! Akhater for your help . . . this guy was up late last night working with me and up early in the morning pressing through with me. I really can't say enough - the points are all your - I wish I could give you more. Although new to Exchange, this experience has made me a much better Exchange admin.

Also, thanks endital1097 for your input.

I am really glad you sorted it out and thanks a lot for the point
