Here's a strange problem:
Synopsis: Two sites, each with a ZyXEL ZyWall 10 - which does ipsec routing. Behind site B ZyWall is a Windows 2003 Server with a shared folder on fake IP. PC's on site A want to connect to windows share on site B. Works in Win98 - doesn't work in Windows XP.
Details: On Windows 98 everything functions correctly. The share contains some
19gb of data, but it all still works fine through the VPN. The ZyWall suggests the connection is established and fine too - and since it works on Win98 one would not suspect the VPN itself.On Windows XP, you can connect to the server. You can login, and then see a list of shares. Some of these shares you can enter - [netlogon] for example, or any others which have little or no content. But you click on [share] - it takes too long and eventually times out (error says permission problem - but I suspect it's not and the message is wrong).
Interestingly, I tried sharing a folder WITHIN share - that worked, until you tried to enter another subdirectory with a lot of files in. Is this an issue of quantity of files? But it works in Win98! And we're not even talking about that many files before it ceases to work.
Windows XP firewall is off.
I have no idea what the problem is. I tried installing an FTP server on the the 2003 server - works in Win98 and not XP. Same with using IIS to serve the files on HTTP. There is *something* that Windows is doing with its networking that makes everything not work over VPN.
But surely VPN is transparently done by the ZyWall's though?
Anyone care to enlighten me? I would much appreciate it!
Thanks,
Terence
