There is no way since a "real" path to a UNC may not exist.

Tend to object, jhance :o)

'NetShareGetInfo()' will provide the local name of a share - I wrote that one a while ago:

(EE's choking on that, so I'll have to split the post)

Yes, you are right.  I misunderstood the question.

I thought he was asking for the LOCAL PATH on the workstation where the app was running.  That would not necessarily be there if the remote path was not mapped to a local drive letter.  But after reading the question I see that your interpretation is probably the intent of the question.
