[THIN] Some users cannot connect to any apps

Here's a fun one.  We have a remote office with 40-45 users.  All but 3 of them can connect to one of our hosted applications.  The 3 are getting the "Cannot Connect to the Citrix Presentation Server".  We have had them (3 people) try to log on using another computer and they get the same error.  I have had working people try to log onto the 3 non-working computers and they do not get the error. 

Sounds to me like it is something to do with the 3 users.  I have verified their AD access and group membership (matches one of the working people) and I have deleted their roaming profile in order to create a new one. 

The error is indicative of their PC not being able to connect to the Citrix server.  We have successfully pinged every Citrix server from their PCs without any issues.  Again, I had other people log into Citrix on their computers and everything works fine.

Has anyone every seen anything like this before?  Online hasn't been helpful so far.

Very frustrated,
