hi everybody and thnx for any help!
shortcut:
i can´t copy from Client1 data from SRV1 if someone else works on SRV1 too!!!!!
my boss told me to install a firewall in our network and i´m not really familiar with firewalling right now, but i already found that ASL-Firewall is really easy to use and the right one.
first the networkstructure:
Clients: Windows 2000
Server: Windows 2000 Server
ASL-Firewall: ASL 2.022
eth0: secLan
eth1: insecLan
eth2: DMZ
Masquerading:
secLan -> DMZ
Rules:
Any - Any - Any - Allow

Problem:
When i copy data from SRV1 via windows explorer to Client1 and another Client tries to copy from the same source Client1 alerts an ERROR and the copy-job is aborted. The other Client can copy till another Client is working on the same source again. this is no alert of the "file is in use" or such thing. the error comes until anyone tries to do something on the same source as another Client.
Error-Message:
datei kann nicht kopiert werden: Der angegebene Netzwerkname ist nicht mehr verfügbar!
file can´t be copied: networkname not available!
datei kann nicht kopiert werden: die Netzwerkresource oder das Gerät sind nicht verfügbar
file can´t be copied: networksource or device not available!
i´ve tried around some D/S-NAT settings, changed between Masquerading and D/S-NAT, but i still get this Error!
what am i doing wrong?
did i miss something?
is this possible? if not, why???
i´ve already read through 3/4 of the bulitin-boad but i can´t figure it out what´s going wrong....
please help?!?!?!
thnx anyway,
