Cannot login to a Vista PC's domain account remotely, but can login to PC local account.

Issue: Vista installed and joined to a Windows Small Business Server 2003 Domain. When remotely accessing the PC it will allow a complete connection only if using an account that is a local PC account.
  Domain accounts always say "The username or password is incorrect." This goes for any domain account that I've tried, Administrator, Users...
  We are heavy users of Remote Web Workplace and need to fix this issue, but I've been unable to do so for a week.

I just noticed this same problem with my Vista machine.  I have not yet found a solution, but the fact that it is happening to both of us, may mean it is not just our networks, and a Vista/SBS problem.

Let's eliminate the basics first.

OS Version
1.  Which version of Vista are you using?
      - Needs to be Businees, Enterprise, or Ultimate

DNS and Conectivity
2.  Can the Vista machines ping the SBS server by name?  By IP Address?
      - By name fails, by IP succeeds: Verify that the Vista machines are configured to only use the domain DNS servers (SBS server)
      - Both fail: Verify connectivity of Vista machines and SBS server?  Validate routes between the 2.

Firewalls
3.  Are software firewalls installed on Vista machines or SBS server
      - Disable any firewalls

4.  Is SBS server running ISA?
      - Add subnet of Vista machines to the LAN network in ISA

Answers to aces4all:

1) OS Version - Windows Vista Business
2) Can ping server - Server shares drive map to the desktop. DNS is working correctly can ping by name
3) Windows Firewall installed but disabled in Group Policy
4) SBS Server is not running ISA

How did you type the user name?

Commented:
Try specifying the domain name with the username either by logging in using UPN (ex: user@domain.com) or NT4-style login (ex: Domain\User).

I have already tried that. Domain\Username returns "The username or password is incorrect."
workstation\local-account will allow login.

I believe that it is a setting in group policy - somewhere - I've checked over the windows vista gp and it looks the same as my test network (where I can log into Vista machines - No Problem)

Just ading fuel to the fire. I have 1 Vista Business mahcine on our domain. Only running 1 windows SBS 2003 server. I have the exact same problem. I have not configured any group policy settings.

Here is a quick test that seems to be failing for me.
I am unable to ping the Vista machine from the SBS. I get name resolution but no response.

That sounds like a possible windows firewall issue to me. Try turning the Windows Firewall on the Vista machine off and see if you can ping the WS from the server.
