Mac OSX Lion - Accessing Shares on Windows 2003 Server

Hi all,

I'm not a Mac expert at all, but manage a Windows 2003 SBS environment and have been asked to get someone's Mac OSX Lion connected from their home via VPN so they can access a shared folder.

I was able to successfully configure the VPN connection and am able to ping the Windows server by IP address, so I know I'm getting a good PPTP connection.

I'm not sure where to go from here, though. When I go to Go/Connect to server and put in the server's IP address or name, it immediately comes back with an error saying that the server couldn't be contacted and to contact your system administrator.

What am I missing?

Thanks,

Tom

the dns settings on the pptp connection must be looking at a internal dns server.

Thanks for the response, valmatic...if I understand correctly, I believe it is.

When the VPN connection is established it gets an IP address using the server's DHCP, which issues the IP address and the DNS server IP address. So right now when I go to the DNS tab of the Mac's VPN settings, ti shows the IP address of the Windows server and it's grayed out.

Also, shouldn't I be able to to connect using the server's internal IP address even if DNS wasn't set up properly?

Thanks,

Tom

Have you looked into a possible firewall issue yet?

Hmmm...no, I haven't. Good idea.

I'm not totally sure what to look for, though, since this all works fine for Windows computers. No problems with accessing shared folders with a VPN connection at all!

Is there a Mac-specific feature I need to enable on the server?

so the windows computers are using pptp as well?

have you tried smb://serverip from the mac?

something else to look at i found.
In a nutshell, the cause of the problem is the default security policy on Windows 2003 Server being set to always encrypt network connections under all circumstances. Whilst this is fine for most clients (especially Windows clients, understandably), the version of SMB that Panther uses doesn’t support encrypted connections. Apparently this support exists in Samba 3, but not on the version OS X uses. The solution is to change the security policy to use encryption when it’s available and not otherwise. Here’s how.

From Administrative Tools, open Domain Controller Security Settings.
Go to Local Policies then Security Options.

Scroll down to find the entry Microsoft network server: Digitally sign communications (always). Set this to Disabled.

The only thing left to do is to reload the security policy, as changes don’t otherwise take effect for some time. Open up a command window and type:

gpupdate

oh i found this from my old server 2003 files. We have a few macs and we used to connect them to 03 server but with 08 server there is not much i have had to do.

This microsoft guide is pretty detailed. SBSMacDoc.doc

Good stuff! Thanks for the in-depth responses. I haven't been able to get in touch with this person yet, but I've already disabled the SMB digitally signed communications and am waiting to test with the user.

Hopefully it'll all work -- I'll be back soon!
