Ok so all your workstations are part of an Active directory Domain.
If you use a Windows XP host, and connect using a V1 profile version, then the application works fine.
But if you use a Windows Vista or above version, using a V2 profile version, then the application doesn't work anymore.
Could it be possible to post a gpresult /z from a Vista or above version?
Maybe you have settings defined by policy to restrict NTLM and/or Kerberos
Are your computers time-synced with your domain controllers?
Any event in the log?
How works the application, where is it stored, OS version?
More details you provide, more we could have ideas.

I think you cannot, but take a closer look here: http://blogs.msdn.com/b/openspecification/archive/2010/04/20/ntlm-keys-and-sundry-stuff.aspx and on the links in the article.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

We find out that the problem that some users are having to access a specific application could be with profiles because all the users reporting problems had their profile deleted. I asked the Admin to copy a profile from a machine that had the application working in a machine that wasn’t working, for
the same user. It worked! The theory is that NTLM doesn’t have enough keys to give to users, since XP used a roaming profile, which means the profile were stored in a server and now with a migration we did to Windows 7 the profile are stored in each machine. That’s why if I
for example, that can access application in my machine try to access the application in another machine it will not work.

One possible solution is to increase the number of keys provided by NTLM. I don’t know if and how it would be possible.

Please find attached gpresult and kindly let me know if you need additional information. I don't know if I am using V2 or V1 profile version. The application is stored in Linux, don't know the version.
