VPN Connection Problems with SBS 2003 and SP1/ISA 2004

Sitting here at SMB Nation and listening to Wayne Small from Australia talk about Mobility and SBS.

One great point to remember that I think is probably overlooked by default. (I know I do.)

If you are having connection problems with your VPN Clients and it seems that you have more than 5 users at one time and ISA 2004 installed from the SP1 for SBS 2003, you may be right! By default ISA 2004 installed only allows 5 users on the VPN at any one time.

Here's what to do:

Go to ISA 2004 Management.
Click on your SBS Server Name.
Click on Virtual Private Networks.
Go to #3 on the VPN Clients tab and click on the VPN Properties link.
Go to the General tab.
You'll see 5 for the number of VPN clients.
Bump that up and you'll see your 6th VPN client connect!
