Slow VPN between Win Xp Pro <--> Win 2000 Server SP4
I have a Windwos 2000 server (SP4) connected via broadband to the Internet. For 2 years I have had users with Win 2000 clients connecting using VPN connection across broadband & dial-up. At the front end of the Win 2000 server I have an Asante Friendlynet FR3000 firewall/router handling the VPN connection. Everything works fine/has worked fine with users accessing the mail server and data server.
I have now connected a Windows XP Pro SP2 user to the VPN and I am having problems - whether I connect via dial up or broadband. The parameters are right because I can make a connection. However, the connection doesn’t always go through. Sometimes it connects immediately, other times it just sits with the ‘Connecting to xxx.xxx.xxx.xxx’ message and then times out with an error message: 'Error 800. Unable to establish VPN connection'.
If I click redial it will either connect immediately or it will take several attempts to connect.
Once connected I can access the server to downlaod emails or directly to folders to download/upload files. But the transfer process is very slow. On a Win 2000 client connected to the VPN a file that takes 7 seconds to copy takes anywhere from 25-105 seconds from the Win XP Pro client. Email collection is equally as bad.
So my guess is that there is some security setting or port access setting that I haven’t found yet on XP Pro.
I am not a trained Windows Server or Windows client techie.. just an experienced user using savvie to set things up... obviously run out of savvie :)
