Error 51: intermittent problem mounting Samba share

[Askew Bernard]

Hi folks

I have a strange problem.
On some NT Workstations connecting at some times following error appears
(German OS).

----------------------------------------------------------------------
Systemfehler 51 aufgetreten.
Der Remote-Computer ist nicht verfügbar.
----------------------------------------------------------------------

which means that it cannot access to the share.

All the NT Workstations are configured identically (as where the problem
doesn't occur)

The mounting is done via following command:
net use k: \\pdmprd.rtc.ch\pdmsdate /USER:RTC_PROD\%username%

If you try it a second time, it works fine

Any idea? Network load? Setting?


Thks
