I've read your link to kb and i don't think that's my problem, because my DC is Windows 2000 Server, and before the migration from the old Windows 2000 Server to the present one i've even reduced the shares (old users...)

For the problem in the Windows 2000 Pro machines i've arranjed a solution... put all use's in lowercase, this is:

USE O: "\\SERVER-LIS-014\ESEGUR-LIS-DGTV"

to

USE O: "\\server-lis-014\esegur-lis-dgtv"

and so on...

i've seen this script somewhere in the forum:
>>>>>>>>>>>>>
$count = 0

;Map X Drive
Do
$mapped = "0"
$count = $count + 1
If $count = "10"
$Window = MessageBox("X Drive Server not available or drive is already mapped.", "ERROR.", 0)
$count = 0
$mapped = "1"
Else
Use X: \\snaplab\xdrive
If @error = 0
$mapped = "1"
EndIf
EndIf
Until $mapped = "1"
>>>>>>>>>>>>>>>>>>>

It creates a loop until it finds the drive

I'll try and post the result
