I haven't used TAS, but if it's a NFS client, then it shouldn't present
anything out of the ordinary. We use Hummingbird's Maestro at work and
I use WinNT and ClearCase with great success.
I'll presume you've setup an NIS/YP server somewhere and that you have a
YP account and have set your local NFS access to use that account.
Something else is weither your unix server is using an ACL for accessing
the vob storage and weither your machine is in the list.

Sounds more like an NFS access problem than anything else.
Try opening a DOS Prompt and using the native 'copy' command to copy a
small file, then try copying a different small file to that same file
as the first copy. If it doesn't work, or doesn't cause the files contents
to change, then it's likely an NFS access problem. If it does work, try
copying a zero length file twice.

Touch should work. ClearCase emulates a unix like filesystem using the
backing-store of the local view for non-clearcase files. As such, you
can create a normal file and perform all the time stamp operations on it
