Q: Take 20 minutes to be able to browse

We deployed VPN site to Site between Site A and Site B. On Site A are all Microsoft resources (DNS, Wins, PDC) We use Win NT4 architecture. On site B : only network components (firewall - witch is DHCP server, switch) Some workstations on site B can not connect to application (http applications, or Exchange 5.5 with Outlook client). From these workstation, we are able to ping with success IP addresses, but we can not ping with success UNC.
At the same moment, for other workstations on site B, applications are running. 20' minutes later everything work !!!

We use Win2K Pro and WinXP. For Win2K we go into the TCP/IP properties of the LAN apapter(s), Advanced settings, DNS tab and uncheck the "Register this connection's address in DNS" box, and Reboot. It seems to be fine now. For WinXP we continue to have these problems. Do you have ideas ?

A: The 20 minutes delay sounds reasonable. It was probably the browser service taking a while to stabilize. Are all the clients (including the XP ones) in both sites set up as WINS clients?
