Hello Bryan,
Thank you for posting here.
According to your description, I understand that 2 remote VPN clients
unable establish VPN connection at the first attempt. If I have
misunderstood the problem, please don't hesitate to let me know.
Based on my research, I suggest we try the following steps to see if we can
resolve this issue:
1. The issue seem the known issue about apply Windows server 2003 sp2 on
SBS. Do you install Windows server 2003 sp2 on SBS? If yes, please perform
the following steps:
1) Update the network adapter drivers
Contact the network adapter manufacturer or contact the original equipment
manager (OEM) for the computer to determine whether an updated network
adapter driver is available. You must have drivers that are compatible with
NDIS 5.2 or with a later version.
2) Modify the registry to disable Receive Side Scaling
a. Click Start, click Run, type regedit , and then click OK.
b. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
c. If the EnableRSS registry entry does not exist, create it. To do this,
follow these steps:
a) On the Edit menu, point to New, and then click DWORD Value.
b) In the New Value #1 box, type EnableRSS , and then press ENTER.
d. Right-click EnableRSS, and then click Modify.
e. In the Value data box, type 0 (zero), and then click OK.
f. Exit Registry Editor.
3) Disable offloading support
a. Click Start, click Run, type regedit , and then click OK.
b. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
c. In the details pane, right-click EnableTCPA, and then click Modify.
Note: If the EnableTCPA registry entry does not exist, create it. To do
this, follow these steps:
a) On the Edit menu, point to New, and then click DWORD Value.
b) In the New Value #1 box, type EnableTCPA , and then press ENTER.
d. In the Value data box, type 0 (zero), and then click OK.
e. Exit Registry Editor.
f. Restart the computer.
2. If the issue persists, I suggest we try the following steps to
reconfigure the VPN connection see if we can resolve this issue:
1) Disable RRAS
a. Schedule a network down time.
b. Please open Routing and Remote Access console on SBS thru run command
"rrasmgmt.msc"
c. Right click the SBSname (local), select Disable Routing and Remote
Access console
2) Run CEICW on SBS
You have to rerun the CEICW to make sure your SBS 2003 server have right
network configuration. Go through the follow KB and Rerun CEICW again
carefully.

3) Run Remote Access wizard
a. On the Small Business Server 2003-based server, click To Do List in the
left pane of the Server Management console.
b. Under Network Tasks, click Configure Remote Access.
c. Click Next, click Enable Remote Access, click to select the VPN Access
check box, and then click Next.
d. Type the fully qualified public domain name (your public DNS name) of
your server, click Next, and then click Finish.
e. When the wizard is completed, click Close.
4) Then you can access RWW to download Connection Manager or copy the file
from SBS server c:\ClientApps\Connection Manager\SBSPackage.exe. Please
save the sbspackage.exe file in VPN client computer. Then double-click
SBSPackage.exe to run it. After this file run the "connect to small
business server" will be created and you can use it to connect VPN to your
SBS server.
If we cannot resolve the issue after we perform the above steps, please
help me collect some information for further investigation:
1. Once the VPN connection is established, run command "ipconfig /all >
c:\ipconfig_sbs.txt" and "route print > c:\route_sbs.txt" on SBS, send the
files c:\ipconfig_sbs.txt and c:\route_sbs.txt to me at
v-terliu@xxxxxxxxxxxxx
2. Once the VPN connection is established, run command "ipconfig /all >
c:\ipconfig_client.txt" and "route print > c:\route_client.txt" on
problematic client, send the files c:\ipconfig_client.txt and
c:\route_client.txt to me at v-terliu@xxxxxxxxxxxxx
3. Do you install ISA server on SBS? What's the edition?
4. Does this issue happen on all VPN clients?
I hope these steps will give you some help.
Thanks and have a nice day!
Best regards,
