Had a similar issue and here is what I did that fixed the problem:

OK, you PDC is a win2k3 server, it needs to be the primary DNS server for itself and all workstations/member servers on the network (AD integrated).

If your XP doesn’t get the IP address from the DHCP, you need to set the primary DNS to your Win2K server as well, you can set other external DNS as your secondary or tertiary if your Win2K3 server doesn’t give you lookups for outside your network. This is to ensure that all workstations know where to find the AD server to get authenticated.

After that is done just to ensure no client issues I went to each client and did the following:

Control Panel
Admin Tools
Local Security Policy
Local Policies
Security Options

look down the list for “Microsoft Network server: amount of idle time required before suspending session – default = 15 minutes”.

Right click and Properties.

Set this to an obscenely large number of minutes.
99,999

next…
on the same list… find:
“Microsoft Network Server: Disconnect clients when logo hours expire”. Right click and Properties.

Set at “disabled”

Hopefully this helps you too,

Regarding the win2k and 10 connections. If u r running Win2k server as stated then that is not the problem. Only pro has a max 10 connections limit.

Regarding Cisco VPN clients. We two had a same problem but our clients were connecting internationally and disconnecting after a time out. Disabling the time out feature on the VPN server resolved the issue. But I gather that this is a LAN set up and not a case of VPN-ing in.

Hope this clears up some,
good luck

Do these machines have the Cisco VPN client installed? We had some machines that had this problem and they all had the Cisco VPN client installed. Removing and re-installing the client fixed our issues.

Thanks,

have you checked the event log(s) of the machine(s) in question and the server when this happens?

If so what does it say?

Cheers

Hi,
I would suggest you check offline folders setup in policy, happens to me that misconfigured policy can behave weird, when u confirm that licensing is ok. Another option is to check Kerberos and security logs – just hint.
