I have a windows 2000 AD server with about10 pcs on teh same subnet. While I have a VPN coming in via a netscreen to my AD domain. However I do notice that it takes up to 30-45 mins for a user to log in from the netscreen site. As against the relatively fast time on my end. The netscreens are coming in via ADSL and are relatively fast. they are also configured to use the DNS server of the windows 2000 domain. Any tek-tips?
