So i realized that some people have had similar experiences with accessing TINs on the network. (Created on local hard drive then moved to network and not being able to open the TIN) My issue seemed identical; i see the data, it even has the correct icon in arcCatalog but i can't view the TIN or open it unless i move the data to the desktop (or other location on C)
I realized that for the last 2 years i have been using Symbolic Linking. All my data is stored on dedicated data drive but a symbolic link is used to make all projects appear as if they were residing on the C drive. This is because i added the dedicated data drive after i have been storing all of my projects on the C drive and it would have otherwise taken me long time to re-link each document....
Long story short; if i add the data from the physical location not via the Symbolic Link, the TIN loads fine.
