One possibility is power management may be enabled on the network adapters, and they are "going to sleep" and loosing the connection. To verify; <right click my computer> Properties | Hardware | Device manager | Network Adapters | <right click your adapter> Properties | Power Management | Make sure "allow the computer to turn off this device to save power" is not enabled

If not the above;
When disconnected can you ping the server that contains the shares to which you map the drives.
If so can you view the share with \\ServerName\ShareName

There is also an issue with drives automatically disconnecting, intentionally, but it is more common with windows 2000. You may want to have a look at the symptoms and solution:

well... you have to check for what time your server is running backups. working on a file that is opened you should know it's not allowed for moving or sometimes copying operations and will disconnect any network connections.

if not then this might be your problem http://support.microsoft.com/kb/297684/EN-US/ ...

give us a little more information. why do you have to reboot the xp machines? do you get any error message or prompt? Can they ping each other? do you have dhcp on your network?

thanks,

I manage a few installations with similar structures. First of all I let 2003 manage DHCP. I set the router with a static ip. I set that ip as reserved in 2003 for the default gateway. I set all clients to obtain ip automatically. Never had any problems.

hi, there

Please give us the following information. Before you reboot the machines can you do the following.

1. ping the server ? by UNC name also per IP address. can yor reconnect doing
\\x.x.x.x\this is the share ?
2. Ping the default gateway ?

It sounds more like a kerberos issue with time synchronization.

Check the clock on the server and see if the client machines are off any. If you set up a log in script that sets the clocks using

net time \\servername /set /y

Try that and see if it helps

im also noticing under the event logs on each client that connects to the domain that "netlogon event 5719" error messages are being displayed.  The times are sporadic and in no specific time period....I have added a time sync script to see if this helps any.

Rob WilliamsCommented:
"netlogon event 5719" can certainly be a time issue and also can be related to physical connection problems as well as DNS. Try running Windows NetDiag to check for any DNS/connection issues if synchronizing the time doesn't resolve. It is available from the Windows Resource Kit or:

If that doesn't work out try running netdiag. Small app, only takes a few minutes but will often locate any network or DNS issues. Let us know how you make out.
