For years we had an SBS 2003 server. We have technicians out in the field that often connect into their computers remotely via Remote Web Workplace from various workstations out in the field. This has been working fine all this time.
Recently we upgraded our server to SBS 2008 and insured we have everything setup properly for RWW (i.e. certificate, firewall ports, group membership, etc.) and it is working fine from most of the machines out in the field except for ones that are Windows 2000 or Windows 2003.
When we try to connect from a Windows 2000 or 2003 computer we get the following error:
The wizard cannot configure Remote Desktop Connection settings. Make sure that the client version of Remote Desktop Protocol (RDP) 6.0 or later is installed on this computer.
When I researched this message the most common solution seems to be resetting IE settings then running "Regsvr32 Mstscax.dll" and adding the site URL to the Trusted Sites list. But that solution does not resolve our problem.
In other articles I read that you must have RDP v6.1 in order to work properly with SBS 2008 RWW but these computers have RDP 6.0 which is the same version specified in the error message. Is RDP v6.1 truely necessary and if so how do you install it on that operating system? The documentation I found on RDP v6.1 says it supports only Windows XP, Vista and Windows 2008. I tried installing it anyway on the 2003 server but I got an error stating that it was an unsupported operating system.
So if everything I found is true then my conclusion is that in order to use the SBS 2008 version of Remote Web Workplace I need to have RDP v6.1 but that version is not available for Windows 2000 or 2003 therefore it's incompatible and there's nothing I can do.
Are my conclusions correct or am I missing something or does someone have a work-around?
Any suggestions would be appreciated.
P.S. I should mention that we have this same problem on all Windows 2000 and 2003 machines regardless if they have IE 6, 7 or 8.
