RE: Demand Dial Problems

I think you might be right on the License issue. I'm close to my max. and I
didn't know that the dod takes a CAL.

This morning the server that hasn't been connecting (Cleveland Branch
Office) connected and the server that has been connecting (Indy Branch
Office) will not connect.

So, I'm in the process of purchasing more licenses. When I get them
installed, I will update this post.

Thanks

Hi Warwick,

Thank you for posting in SBS newsgroup.

From the description, I understand the issue to be: you have created site
to site VPN from 2 branch offices to SBS, however 1 branch office can not
connect to SBS and got some error message. If I have misunderstood your
concerns, please do not hesitate to let me know.

Based on my knowledge, the issue could be caused by the following
possibilities:

1. The connection number reaches the limitation configured in RRAS.
2. License issue.

The default maximum connection number is 5 on RRAS. You may try to increase
the number to see if the problem can be resolved. Open Routing and Remote
Access console, navigate to ports snap-in. Right-click it and choose
'Properties'. Double-click WAN Miniport (PPTP). Change the maximum port
number to 10. Click 'OK' to close the dialog boxes. After doing this, open
services.msc and then restart the RRAS related services. Can you then make
more VPN connections?

For the SBS server, each authorized connection may take one CAL. Could you
please let me know how many CAL you have installed on the server? Do you
use dedicated user accounts for the DoD connections? Please open Server
Management console, navigate to licensing snap-in. Check the installed
license number and maximum usage number in the right panel. Also, you may
open event viewer and check to see if there is any licensing warning or
errors.

If the problem still occurs, would you please help me collect the following
information?

1. Can you ping destination VPN Server or gateway when the issue occurs on
problematic branch?
2. The 20111 error is usually due to firewall/NAT devices not passing the
L2TP packages. Do you have NAT server or devices on problematic branch?
3. Have you done any changes on problematic branch? Are there any
difference between normal branch and problematic branch?
4. Are there any hardware devices before SBS and branch office network?
5. Please follow the steps below to enable PPP logging and post the log
files for analysis:

1) On the SBS server, click Start, point to Administrative Tools and click
Routing and Remote Access.
2) Right-click your server, click Properties.
3) On the Logging tab, select Log all events and Log additional Routing and
Remote Access information (used for debugging). Click OK.
4) Right-click your server, point to All Tasks and click Stop.
5) Open Windows Explorer, move the files in the C:\WINDOWS\tracing folder.
6) In Routing and Remote Access right-click your server, point to All Tasks
and click Start.
7) Reproduce the issue.
8) Zip the files in the C:\WINDOWS\tracing folder and post it to newsgroup.
