Try Start->Run->CMD /C NET USE * /DEL
and clear all your mappings and re-run it...

Hi,

i found this (possibly matching) answer by crawling through the net:

========================================
This error can occur if the drive letter you are mapping with a net use command is already mapped in the user's properties.

NOTE: Open a CMD prompt and type net helpmsg 85.

Home drive mapping is processed before the logon script runs. If the home drive maps the drive letter successfully, the logon script fails because the The local device name is already in use.

To fix the problem, change the drive letter mapping in the logon script or in the home drive
========================================

So the problem seems to be, that your home drive is mapped to the letter where you want to map something in your logon.bat
Solution: change the homedrive-mapping or the letter in the logonscript - whatever fits best for you

regards
Holger

Note:
As you told, that you have normally no problems with the logon.bat, that issue could be a userspecific (as homedrives are mapped userspecific)

Can you ping the host you're trying to map to?

By the hostname you're mapping with?

From the command line (start/run 'cmd'), try a 'net view \\hostname'... do you get an error there, and if so, what is it?

Also make sure your domains/workgroups match, and that your IP domain name is the same.

If the PCs are not in a Domain-context, they needn't have to be in the same workgroup! This is often said but never true... workgroups only group PCs visibly in the explorer but there's no security in any manner!

As the logon script starts, there must be an IP-connection - no need to ping the host

The problem is not the connection, but the "net use ... " command issued to a drive-letter that is in use
