Terminal Server User can not see any of the words on the buttons when logging into PFIT via TS.
This looks different than just the fonts not being installed.
This problem has come from the fact that the Omnis folder, for the TS user is not read write.
To fix you may need to delete the Omnis fonts for the user who installed Omnis first. Then make sure all omnis folders on the TS are Read/Write.
Next, install the Omnis fonts. This may need to be by logging in as each user and installing the fonts separately.
From my experience fixing this problem is not an exact science. It make take some trial and error. The root of the problems seems to be read/write access to omnis.
