In my office , I use a Program that uses an "aplication server " ( a
service ) in the Server and for stations ( clients ) accessing the
server .
The Program is not installed ( in the conventional way ) . You just
install the "Service" , and copy from a CD the requiered files , in
local folders in the Server and Clients
The *.exe files , recognize the "Aplication Server " , installed in
the SERVER
To make it clearer



SERVER \\ BASE D:\MLMaster
Station A C:\ MLMaster
Station B C:\ MLMaster
Station C C:\ MLMaster
Station D C:\ MLMaster

There is no need to Map the drivers - I just have to set up a normal
home -small business network and run the program from Server or
Client , using the main Executable in each Server or Client , on the
folders above
The Upgrades , are done by the software company at night , upgrading
the files in the Server :

D:\MLMaster
A Copy , of the upgraded files is placed in a subfolder :

D:\MLMaster\ClientADV

The Client stations , at startup run a batch file ( at the startup
menu ) , with the following command line : ( copy from
D:\MLMaster\ClientADV )

%windir%\system32\xcopy.exe \\BASE\ClientADV\*.* c:\mlmaster /y

Stations A (Pentium IV 1GB RAM ) and B ( SEMPROM 2800 512 RAM ) have
no problem upgrading

Station C (SEMPROM 1500 256 RAM does not upgrade - Not using the
command line - I can copy and paste from D:\MLMaster\ClientADV

Station D (Pentium III 800 384 MB RAM ) Can´t upgrade using the
command line .
It freezes in the middle of the copy and CANNOT upgrade by using
copy and paste from D:\MLMaster\ClientADV
The only way to copy the files is by using a Pen drive.
( Or ziping the files and copy the zip.file )
The error I get when trying to copy with copy and paste , at
station D , is , that after 2 or 3 files , windows says , "the Network
path is no longer valid "

I´ve talked to the Support people , and as usual I heard the " you
should format " the problem stations.
I tried other ways , like mapping the drives ( changing the command
line to the mapped drive) , running Scandisk at SERVER ( Pentium DUAL
Core 2 GB RAM ) , and stations ) .
I tried also changing the Network adress a station D . The
comand line is OK in all stations
All stations and Server are running winXP PRO SP2 - I can copy
any file from any stations or server ( including problem stayion D )
with the exception of the files of Server at D:\MLMaster\ClientADV.
(So I figure the Network is OK )
No computer is firewalled, and the Network is a convenitional
192.168. etc.etc
The gateway to the Internet is a Linux system computer , with
the firewall.

I finally gave up and decided to give it a try ; instead of
formating station D , ( FAT 32 ) I erased all files at the root of the
drive using XTGold , and deltreed , Windows ,
Program files , Documents and settings , Recycle Bin etc , and all
folders native to the Windows install ( This way , I preserved my
files in the HD )
When install was completed , before anything could be sent to
the registry ,I tried copying files from (Server ) MLMaster\ClientADV
- Same error.
Can one of you help me on this issue ??
