client unable restablish connection to server2003

[sirpelidor]

Greeting, this is the first 2003 I've ever played with, so please be patience with this newbie

problem:

local client machines (winxp pro) and server (2003 sbs) on the same network, all client machines have mapped a drive (lets call S: drive) to one of the 2003 folder so staffs can share files among computers. client machines lose connection to server after certain amount of idle time (length of time is inconsistence, some can go on days, some overnight) when lost connection, client machine needs to reboot in order to get connection back.

addtional information:

-no red line/red cross at S drive icon

-when click on S drive, it ask me to login, but yet it doesn't recongize administrator account and password

-click window explorer unable to establish connection back to the server

-reset server timeout to never, problem still there

-changed net server config to -1 on client machines, problem still there

-edit lmhost.sam at client machine, problem still there

-not all machine lose connection at the same time.

-(most important piece of info) my machine is the -only- machine that can talk to sever2003 when every machines lost connection because of idling. and my machine's (the only machine) domain is connect to NT4, and I just mapped a drive to 2003 folder while everyone else is on the 2003 domain.

I've search all over google, and I think I did all i could, I don't know where else to go from here

thank you

these client machine lose all lan functionality? can they access internet? are you using dhcp/dns servers?

Hi coconut, thanks for the reply.

No client machine still have access to the internet, just lose access to the 2003 server.

my network setup is (internet) - (firewall/router) -(internal network, xp client and server sbs)

meaning even if the server is down, all my machine still have access to the internet

thank you
