Client cannot connect to MCRM server

I have a single user that is unable to connect to MCRM 4.0 web server. He is external accessing the external portal.

Ive done some initial troubleshooting and I'm completely stumped:

I verfied all his CRM settings, and everything is correct.
I can access the site internally, and other users can access the external site.
He can ping and tracert to the server, and he can also access other external network services(web mail, vpn, etc)
I've verified all his browser security settings and it mirrors other clients that are able to connect.
I've shut down windows firewall and any other form of security that could be blocking access.

The only difference between him and other users is the fact that he is on Windows 7. This leads me to think that it could be some kind of windows 7 issue...

Does anyone know of some other troubleshoot steps or a fix for this particular problem?

Does he get an error? What are the details of error? How far does he get? Has he tried using a non-Win7 PC? He is in AD correct? Did his AD account name change for some reason? for example, is his name 'Anthony Smith' and Asmith was his AD , but for reason it was changed to Tsmith for 'Tony Smith.' If this happens, it will cause problems.

I have used CRM successfully with Windows 7. There should be no issues with Win 7.

As iamozymandias asked, it would help if you get post a screenshot of the error.

Did you try turning off the firewall on the Windows 7 PC?

No, none of the comments solved the issue. I dont mind rewarding points if an answer works.


Here are more specifics to clarify, keep in mind I paid microsoft support about $780.00 to get this fixed:

The issue was in the orginal installation of the MCRM server, the consults who installed the server-side failed to follow the best practices implentation guide regarding FQDN and instead used a work around that was valid for Windows XP. However Windows 7 security features changes the way applications interact with the domain, causing ALL Windows 7 clients to fail when attempting to connect, which was isolated to a faulty install of MCRM server. This probelm occured regardless of rollup version or client-specific builds.

The solution was resolved by re-doing the server configuration, since our domain uses .corp for internal and .com for external, the hostname was changed from name.<doman>.com/corp to DNcorpmcrm.<domain>.com

example abc.domain.corp was changed to abccorpmcrm.domain.com

Response 1 failed to answer by suggesting the firewall. My initial post mentioned the firewall was checked. I also mentioned he is able to connect to all the network services, which would rule out any potential AD authtentication or resolution issue.

Response 2 didnt respond to the question, simply made a comment that was...rather not helpfull.
