i came following. allows characters such _, ., , - in names, might want adjust depending on server/share names like. requires server , share name, , makes directory within share optional.

^\\\\[\w\-.]+\\[\w\-.]+\\[\w\-.\\]*$  ^\\\\        --> double-backslash @ beginning [\w\-.]+\\   --> server name (at least 1 character) followed backslash [\w\-.]+\\   --> share name (at least 1 character) followed backslash [\w\-.\\]*$  --> directories (0 or more characters including backslashes)
