Well, it is on the first call.
But not on the first try, ie x://ls, x:/ls, x://ls.com, x:/ls.com where
first tried without hang. But then comes x://ls.exe which triggs the hang.

truename X:\ls reports X:\LS

truename X:\\ls reports folowing error message (in french) after, say,
30 secondes: Not possible to find specified computer name in network path

truename X:\\ls.exe hangs (after waiting 3 minutes, I stated that it has
hang)

stat 0 X:/ls works and reports:
	DOS 7.10 (MS-DOS)
	X:/ls: lossage: No such file or directory (ENOENT)
	Everything checks out OK

stat 0 X://ls reports same thing but takes a bit more time to answer.

stat 0 X://lx.exe reports: DOS 7.10 (MSDOS) and then seems to hang...

Something like Microsoft Systems Management Server, NetWare.
