I am trying to monitor file activity from a WD 500GB harddrive that is connected to a router via CAT5/RJ45 cable. I believe my code is correct since I am able to monitor file activity on C:\ etc. but does not monitor my mapped network drive (Z:\) when I change/delete/create a file from any computer on the network.

I AM able to retrieve drive information using DriveInfo.

Any suggestions? Thanks

While I'm not an expert on this, I imagine this has to do with the way the file watcher works.

I suspect that a file watcher class talks with the operating system through some windows APIs that talk with the operating system disk I/O. When you save a file in windows, the file I/O notifies the "watchers". However, your networked file system is not controlled by (only accessible from) windows. So windows doesn't know about changes as they occur.
