Remote Web Workplace "Connect to a Computer" button is not working

I am trying to setup Remote Desktop using RWW.  I can get to RWW from external network.  I get the button for "Connect to a Computer" and when I click on it I get a list of the internal client/server systems. I select a system and get the messages asking to share printers and clipboard I click Connect and a username and password window comes up.  I put the username and password in and a few seconds later I get the username and password screen again.

I've logged into the security server on EBS and turned on logging in Forefront while trying to connect.  Here is the error I get:

how are you entering the credentials? it should be domain\username

Have you installed the certificate onto the client machine that you are making the connection from?
You can see by the error message that the access is blocked becuase it is being seen as an anonymous access attempt.

Thanks for the response.  I do enter username as domain\username and I have loaded the certificate on the client machine....BUT....I'm not sure if the same certificate was loaded on the server.  I took over the IT responsibilities about two months ago and have had all kinds of strange problems.  I actually had to call Microsoft for the first time in over 20 years of working IT.

OK....I just checked the certificates that they bought from and found a number of dublicate certificates with different thumbprints.  I've checked the servers and found a mess of certificates.  So I've got new questions now:

What should be my next move, maybe get rid of the certificates on the message server and install one from digicert?

Is the message server in EBS the only server that needs public certificates?

Thanks for your comments Keith.  Any other help will be appreciated.
Keith AlabasterEnterprise ArchitectCommented:
no - as I recall there is a folder on the EBS box (at least there is on an SBS 2008/2008 R2 box) that contains the certificate that RWW is using. Copy this off to a memory stick or get it emailed to an outside machine and get the cert installed.
10 Tips to Protect Your Business from Ransomware

OK....I'll try that tonight or more likely tomorrow.  I've been up for a few days now working on this and other problems.

I went to TS Gateway properties and it didn't have any allowed computers selected or a SSL certificate.
I created both but I'm not sure which certificate to use because when I use the certificate then remote web workplace and owa does not work.  We don't have a certificate from our provider that shows certificates.  It only have,,, and xxxUCCertificate certificates.  When I tried to make a self signed certificate and exported it to the client then I could get the Forefront TMG login but can get the RWW or OWA page.  Any suggestions?
NSI-GregAuthor Commented:
last comment should say I can not get the RWW or OWA page.

seems to be a problem with the ISA server. have you ever checked MSKB 947124?

Error message when a user visits Web site that is published by using Microsoft ISA Server together with client certificate authentication:
Error Code: 403 Forbidden.
The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202)

bbao thanks for the comment.  I followed the instructions but I'm still having the same problem.  Thanks for the try though.
NSI-GregAuthor Commented:
Opened a case with Microsoft yesterday to resolve this problem.  Turned out that the RWW publishing rule had two public names listed.  Once we deleted the public name not needed it corrected the problem.

could you please explain a bit more about the PUBLIC NAMES? what's that?

BTW, i have no problem regarding the close request, though i would recommend you PAQ this question by accepting your own comment (explanation) as the answer. this would benefit other members who might have the similar problem.

bboao:  The Forefront TMG server publishing rule for Remote Web Workplace has a tab called "Public Names" under properties.  That is where we found the two names: and

I have no idea how got there but we removed it and RWW started working.
bbaoIT ConsultantCommented:
it seemed to be a DNS issue because the deleted item was not a valid domain name that could be resolved by remote computers.
NSI-GregAuthor Commented:
I requested the resolution notes from the Microsoft tech and this is what he said:

Resolution - We verified RWW working fine internally External users were getting continues login prompt after selecting the computer from RWW list We disabled a costumed RWW publishing rule We found that on the RWW default publishing rule we have two public name. the certificate is issued to Hence removed the entries for even though we connect using tsgateway to Still we getting prompted for authentication We found in the Outlook Anywhere & Terminal server publishing rule The name misspelled We changed that RWW working fine now We monitored the case for a day"

So looks more like a typo in the Outlook Anywhere & Terminal server publishing rule.  That makes more sense
