Hi,
One of our sites in Europe has just moved location and lost their leased line and are now working over a SDSL 20MB line using a Checkpoint VPN device.
Their domain is a child domain (AD 2000 mixed mode) and we are experiencing all kinds of latency problems now.
The ping response between their DC and the parent DC in london averages out at 30ms, infact all ping responses are good.
There are a few issues ive found already:
1) When i try and manage the child domain from ADUC on my machine in London it takes forever to connect to the domain and usually fails and tells me that the RPC timed out, so i have to VNC/RDP onto the domain controller in the VPN site inorder to admin the users there.
2) We have a ISA proxy server in London which all sites connect through to gain access to the Internet and whenever users in this VPN site try and connect now it takes quite a long time (few mins) and will then eventually popup with an authentication box (as though win authentication is screwed) and if they put their credentials in it seems to work. Ping response from the users machine to the proxy is 30ms.
3) Outlook on their machines is very slow (connects to an exchange server in london), to try and alleviate this i am now running cached mode & downloading headers only, which seems to have helped a bit, but can sometimes hang.
Im pretty sure this is all down to the fact they are now running over the public internet and obviously there are some dropped packets here and there.
I have done a dcdiag anf netdiag on the DC in the VPN site which is below:
