Win 2000 NAT doesnt respond

[MegaCale]

Hi.

We have recently moved to a new ISP and as such needed to change a few settings on our NAT server. It has been working for nigh on 3 years non stop now, but as of the change, my NAT stops responding after about 3 hours use by my clients.

More Info.

We have 50 clients on the intranet with static assigned IP addresses in the 192.168.x.x range.

New Cisco 1700 router installed with new ISP. I SUSPECT that they have NAT installed on the router aswell. ( Will this affect my problem ? )

what exactly in your setup? and once your problem occurs how far does a tracert get you?

thanks

Hmm, no error logs get generated by Win 2000, but ill see what ping and tracert can do for me. Thanks for the suggestion thus far.

sorry i ment to say what exactly is your setup, i just wanted to create a mental map of your situation and then from a tracert we could determine where the problem may be

You won't always get an error in a log. Please check the internet connection status tray icon. Does it report errors in received and/or sent? If it does, you may have a buggy modem driver or even worse, a bad modem!
